The academic professoriate is a determinant of successful higher education systems. Yet, recently, worsening conditions of employment, deteriorating salaries, and threats to job security have made the academic profession less attractive, especially to young scholars, in several countries. This paper investigates the salaries as well as the recruitment and retention procedures in public higher education institutions from a cross country perspective. The UK, Germany, France, and Italy are adopted as case studies to determine the attractiveness of European higher education systems. The evolution over the last decade creates an extremely variegated picture.

This report summarises the outcomes of the first (micro) phase of the thematic country reviews (TCRs) on upskilling pathways in France, which reflect the points of view of both the beneficiaries of the outreach and guidance schemes and services under investigation, and the professionals involved in their implementation. The TCR on upskilling pathways for France highlights outreach and guidance for low-skilled adults, and the crosscutting dimensions of governance and financial and non-financial support in relation to the two areas of focus. Cedefop's work on the thematic country reviews on upskilling pathways aims at supporting Member States in the development of systematic, coordinated and coherent approaches to upskilling pathways for low-skilled adults. The aim is to undertake in-depth reviews of countries' national approaches to the implementation of the upskilling pathways Recommendation, with the support of key national stakeholders. France and Italy were the first two countries that undertook this TCR exercise in 2021; implementation is expected to last until the end of 2023.

This report describes how entrepreneurship competence is embedded in vocational education and training (VET) in France. It complements existing knowledge with examples of methods, tools and approaches that can help policy makers, VET providers and other stakeholders build better entrepreneurial learning ecosystems. The report is based on the research of Cedefop's study "Entrepreneurship competence in VET." It is part of a series of eight national case studies (Spain, France, Croatia, Italy, Latvia, Austria, Finland and Sweden) and a final report.

Intersectionality highlights that different aspects of individuals' identities are not independent of each other. Instead, they interact to create unique identities and experiences, which cannot be understood by analysing each identity dimension separately or in isolation from their social and historical contexts. Intersectional approaches in this way question the common classification of individuals into groups (male vs. female, immigrant vs. native etc.), which raises important implications for the policy-making process. In education, analyses with an intersectional lens have the potential to lead to better tailored and more effective policies and interventions related to participation, learning outcomes, students' attitudes towards the future, identification of needs, and socio-emotional well-being. Consequently, as elaborated in this paper, some countries have adjusted their policies in the areas of governance, resourcing, developing capacity, promoting school-level interventions and monitoring, to account for intersectionality. Gaps and challenges related to intersectional approaches are also highlighted.

Calls for increased monitoring and evaluation of education policies and practices have not, so far, included widespread and consistent assessments of the inclusiveness of education settings. Measuring inclusion in education has proven to be a challenging exercise, due not only to the complexity and different uses of the concept, but also to its holistic nature. Indeed, measuring inclusion implies analysing a variety of policy areas within education systems, while also considering the different roles of the system, the school and the classroom. This paper discusses the application of the input-process-outcome model to the measurement of inclusion in education, and key indicators that can be adopted by education systems and schools to this end. It makes considerations relevant to policy makers when designing indicators to measure inclusion, such as the extent of their application, the constraints related to data disaggregation and the relevance of intersectional approaches to inclusion.

With the rise of polarization and extremism, the question of how best to transmit civic virtues across generations is more acute than ever. In this paper, we test the hypothesis that schools can be the place for this transmission by empowering students and gathering them around concrete and democratically chosen objectives. We draw on an RCT implemented in a large sample of middle schools in three European countries. The evaluated program leads students to carry out collective citizenship projects in their immediate communities under the supervision of teachers trained in student-centered teaching methods. The program significantly increases student altruism, their political self-efficacy as well as the quality of their relationship with their classmates and their respect for the rules of school life (less sanctions and absenteeism). In all three countries, the benefits are greater for students with the highest level of altruism and interest in politics at baseline. Investments made at an early age appear to be complement to those made during adolescence for the production of civic virtues.

Climate change and natural disasters, the COVID-19 pandemic, and geopolitical shocks have increasingly disrupted school education around the world in recent years. Whether leading to school closures, school destructions or repeated interruptions in students' learning experiences, these external shocks have translated into lost learning opportunities for students. In this context, education systems face heightened pressure to become ever more resilient, enhance the efficiency of public spending and address emerging learning gaps. This working paper highlights key education strategies for helping students catch up on lost learning opportunities and bridge learning gaps, based on a review of research and policy evidence from OECD and non-OECD countries. It examines a range of academic strategies to address learning gaps, including: (1) adapting instructional strategies and pedagogies to individual needs; (2) extending and adapting the time of instruction; and (3) providing curricular flexibility and enabling fluid learning pathways within the school system. It provides research evidence on the effectiveness of such strategies, together with examples of their large-scale implementation and cost-effectiveness considerations. While this paper presents programmes of general interest for all countries, a separate policy brief targets learning recovery strategies for students in Ukraine.

Several concurrent trends are increasing the likelihood that short courses, microcredentials, and flexible learning pathways will become a regular and even dominant feature of education and training globally. This policy paper reflects on these trends with special reference to the post-secondary education sector, and explores ways to organize short courses and micro-credentials as effective tools for offering up-to-date, quality learning to much larger segments of the population, creating flexible learning pathways, fostering learner autonomy, and formally acknowledging competencies. The paper discusses existing definitions and proposes a universal working definition for micro-credentials developed by UNESCO. It also describes 10 challenges that potentially threaten the successful roll-out of microcredentials. Challenges range from concerns -- some justified, others less so -- about the quality of pedagogy to doubts about level, credit points, progression, coherence, assessment, certification, and labour market value. The paper assesses each challenge and identifies actions that could contribute to the successful roll-out of short courses and micro-credentials. These include a functioning national qualifications framework, transparent recognition procedures, internal and external quality assurance, reliable assessment, facilities for digital storage, funding for learners and providers, and stakeholder engagement. Lastly, success also requires the development of easily accessible digital registers of learners' achievements, micro-credential qualifications, short courses, providers, assessors, awarders, quality assurance agencies, credential evaluators, employers, and job and promotion opportunities. The paper draws on country experiences, studies, and projects from all world regions, and highlights good practices. It concludes with seven recommendations targeted at public policy-makers to foster coordinated action, including further research to better understand short-course provision at country level and obstacles to the development of micro-credentials, as well as their added value for individual learners, the economy, and society at large.

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the first to assess consistency of results by agency. We find results vary by agent, but consistent with Flynn effects, gains are larger in math than reading, except for the most recent period. Non-whites progress at a faster pace. Socio-economically disadvantaged white, black, and Hispanic students make greater progress when tested in elementary school, but that advantage attenuates and reverses itself as students age. We discuss potential moderators.

The feedback between vocational education and training (VET) and the labour market can provide important input for the review and renewal of qualifications. A feedback loop that is based on learning outcomes helps provide deeper insights into what is required on the labour market, what is offered in training provisions and assessed at the end of a learning programme. The aim of this study is to contribute to strengthening the quality and relevance of qualifications and completing the feedback loop between education and the labour market. It examines methods of collecting data on the match/mismatch between qualifications and labour market requirements, including analysis of how achieved learning outcomes are applied and perceived in the labour market (for example methods of collecting the experience of employers with holders of these qualifications). This report addresses the following two questions: (1) which data already exist in the countries, providing insight into the relevance of qualifications to employees, employers and other labour market stakeholders?; and (2) how can survey methodology be designed to systematically capture the experiences and appreciations of employers as regards the content and profile of qualifications? To what extent, based on limited testing, can scalability of the methodology be achieved?

With a view to identifying inclusive policies and good practices to respond to the many challenges that refugee students face to access higher education in their host country, this Policy Paper has conducted a review of available statistical data and literature. In addition, six selected countries with considerable refugee populations have been analysed more in-depth. They are: France, Ethiopia, Egypt, Germany, Norway, and Turkey. From this analysis, the paper presents inclusive policies and good practices from these countries and their higher education institutions by type of obstacle to accessing higher education. It concludes by presenting 15 recommendations on how host countries can support the access of refugees to their national systems, arguing strongly for an 'equality opportunity approach' in terms of national policies, and caring measures, at the level of higher education institutions.

Validation and guidance help individuals, organisations and Member States adapt to career challenges and create successful lifelong learning systems. However, little is known about how they are linked in practice and how this connection can be made more efficient. Building on Cedefop's expertise in the two areas, this study -- based on analysis of 13 practices from 12 countries -- explores how coordination between career guidance and validation of non-formal and informal learning can be improved. Results point to three factors: (a) comprehensiveness: provision of adequate information and guidance before a decision to undergo validation is taken, throughout the entire validation process, as well as after it; (b) coherence: use of common qualifications or competence standards, occupational standards or other reference frameworks in all the stages of the practice to identify, document and assess skills; and (c) quality of staff, resources, competences, and tools used. The study concludes with policy recommendations on how to improve the link between guidance and validation.

This research paper is the fifth in a series produced as part of the Cedefop project The changing nature and role of VET (2016-18). Based on comparative analysis of labour force survey data from 2014, the report analyses the vocational effect on labour market and education outcomes, asking whether any advantages conferred by vocational qualifications in early career would be offset by disadvantages later in life. The report explores the functioning of the safety net and the diversion effects across countries, demonstrating how these vary considerably with the specific institutional structure of schooling and work-based training. The results indicate that VET graduates are potentially sacrificing the longer-term gains associated with further education in favour of short-term benefits.

In a highly competitive global landscape, occupations are transformed, new jobs are created and the skills needed for the labour market are constantly changing. European countries are looking at redefining VET [vocational education and training] to respond promptly to such challenges and take advantage of the opportunities ahead. They are reforming to modernise their VET systems and strengthen the relevance of their national qualifications in an international context. This publication explores national responses to globalisation in 15 countries and five economic sectors. It aims to understand how European and international initiatives help VET renewal across Europe. It shows how countries' reactions are embedded in their national traditions but also depend on their interactions with European, sectoral and multinational players that provide training and award qualifications.

Countries consider curriculum reform as an important and necessary measure to make schools enter the 21st century and respond to a fast-changing world. In recent years, many OECD countries have engaged in curriculum reform as a way to equip children with the knowledge, skills and competences needed for tomorrow. However, how to initiate such change in the most suitable and effective way remains somewhat challenging. In other words, there is a missing step between the intention, and the realisation of this curriculum renewal, crystallising what has been coined in the literature "the implementation gap". This paper analyses the curriculum reform literature through the lens of the OECD proposed implementation framework that promotes, among others, inclusive stakeholder engagement. Curriculum reform has indeed long been considered from a "top-down" perspective, but has progressively shifted towards a more "bottom-up" approach, emphasising the central role of teachers in the process. The analysis is enriched with successful practices and examples from different countries, and concludes with a specific resource for countries to make the lessons learned actionable through the planning of a coherent curriculum implementation strategy.

This paper aims to survey the current landscape of education policy evaluation across OECD countries and economies by examining recent trends and contextual factors that can promote more robust education policy evaluation, as well as identifying key challenges. It takes a view of policy evaluation as an activity that takes place throughout the entire policy cycle, before, during, and after a reform is implemented. It proposes a supporting framework for education policy evaluation that integrates institutional factors which can help to build robust underpinnings for policy evaluation. It also presents some specific considerations to take into account for individual policy evaluation processes. Analysis of more than 80 evaluations across OECD education systems provides an indication of the diversity of approaches taken in the policy evaluation process. Key findings refer to the "who", "when", "what", "how", "for what" and "what next" of policy evaluation processes through a comparative lens.

Governments recognise that careers guidance, underpinned by accurate labour market information, can help learners make post-secondary education choices that match their interests, aptitudes and abilities, and lead to rewarding employment. For this reason, they have invested in building linked education/employment information systems and other information resources which are displayed on websites targeted to learners and their families. However, researchers and governments agree that these efforts are often ineffective in informing learners' decisions -- access to information is not sufficient to provide effective support to student choice. Drawing upon the insights of behavioural economics, this paper examines how learners access and use information, and what this implies for the design of public study and career choice websites that aim to effectively support student choice. The report also takes stock of the career guidance websites in use in the majority of OECD countries, and sets out to provide actionable advice for policy makers to guide the design of effective information policy levers that support student choice.

The paper investigates two -- often disconnected -- policy questions: how can we scale the use of evidence in teaching practice, and how can we generate and scale innovation? Both questions necessitate understanding how teachers and schools connect with each other, and with other organisations and professionals. The paper thus explores the role of networks in scaling evidence and innovation through a review of literature and a number of short case descriptions. Through the lens of networks, the analysis shows how the mobilisation, construction and diffusion of knowledge are of central importance in both policy issues. It suggests that scaling evidence and innovation should be treated as one ecosystem, in which mechanisms that allow effectively blending research and practical knowledge are key. Further, the paper proposes a framework for studying knowledge dynamics in networks to better understand how their context, characteristics and devices can contribute to facilitate these dynamics.

The worldwide school closures in early 2020 led to losses in learning that will not easily be made up for even if schools quickly return to their prior performance levels. These losses will have lasting economic impacts both on the affected students and on each nation unless they are effectively remediated. While the precise learning losses are not yet known, existing research suggests that the students in grades 1-12 affected by the closures might expect some 3 percent lower income over their entire lifetimes. For nations, the lower long-term growth related to such losses might yield an average of 1.5 percent lower annual GDP for the remainder of the century. These economic losses would grow if schools are unable to re-start quickly. The economic losses will be more deeply felt by disadvantaged students. All indications are that students whose families are less able to support out-of-school learning will face larger learning losses than their more advantaged peers, which in turn will translate into deeper losses of lifetime earnings. The present value of the economic losses to nations reach huge proportions. Just returning schools to where they were in 2019 will not avoid such losses. Only making them better can. While a variety of approaches might be attempted, existing research indicates that close attention to the modified re-opening of schools offers strategies that could ameliorate the losses. Specifically, with the expected increase in video-based instruction, matching the skills of the teaching force to the new range of tasks and activities could quickly move schools to heightened performance. Additionally, because the prior disruptions are likely to increase the variations in learning levels within individual classrooms, pivoting to more individualised instruction could leave all students better off as schools resume. As schools move to re-establish their programmes even as the pandemic continues, it is natural to focus considerable attention on the mechanics and logistics of safe re-opening. But the long-term economic impacts also require serious attention, because the losses already suffered demand more than the best of currently considered re-opening approaches.

This paper tests if gender-discrimination in grading affects pupils' achievements and course choices. I use a unique dataset containing grades given by teachers, scores obtained anonymously by pupils at different ages, and their course choice during high school. Based on double-differences, the identification of the gender bias in grades suggests that girls benefit from a substantive positive discrimination in math but not in French. This bias is not explained by girls' better behavior and only marginally by their lower initial achievement. I then use the heterogeneity in teachers' discriminatory behavior to show that classes in which teachers present a high degree of discrimination in favor of girls are also classes in which girls tend to progress significantly more than boys, during the school year but also during the next four years. Teachers' biases also increase the relative probability that girls attend a general high school and chose science courses. The following are appended: (1) Do teachers' characteristics affect the gender bias?; (2) Estimation of the gender bias if the blind and non-blind scores do not measure the same abilities; and (3) Measure of the omitted variable bias affecting ? and a[subscript 2].

Are teachers and principals aligned in their perceptions of the core components of the theory of Leadership for Learning across countries, or are there subgroups of schools in which there is misalignment? The purpose of this study is to examine the extent to which a congruency-typology model of leadership for learning is distributed across countries/economies using the TALIS 2018 dataset through examining the interaction of significantly different subgroups of teacher and principal responders through using multilevel latent class analysis (LCA) with a cross-level interaction. I analyse data from lower secondary schools of n=152 635 teachers in 9 079 schools and their principals across 47 countries/economies. Currently in the research literature on school leadership, leadership for learning has emerged as a framework to bring together managerial, transformational, distributed, and instructional leadership. Yet little is known about leadership for learning across national contexts. This study 1) maps the TALIS 2018 survey items to the current literature and surveys for leadership for learning, 2) then details the methods and analysis framework to examine if there are multiple significantly different types of teachers, principals, and schools from a leadership for learning theory framework. The final model 3) identifies a three-group teacher typology and a three-group principal typology, linking these types to school context, covariates, as well as teacher and principal training and experience. Results relate directly to the intersection of research, policy, and practice for training and capacity of school leaders across 47 countries/economies globally.

This systematic review investigates the relevance of general pedagogical knowledge for successful teaching. It synthesises the empirical evidence of 10 769 teaching professionals and 853 452 students from primary to tertiary education in 21 countries. The meta-analysis of 20 quantitative studies revealed significant effects for teaching quality and student outcomes (Cohen's d = 0.64 and 0.26), indicating that more knowledgeable teachers achieve a three-month additional progress for students. The three themes emerging from 31 qualitative studies underline that general pedagogical knowledge is a crucial resource for teaching. Results also show that teaching requires knowledge about a range of topics, specific skills and other competences to transform knowledge into practice. Teachers need training and practical experience to acquire knowledge, which they apply according to the pedagogical situation at hand. The results allow for important conclusions for policy, practice and research.

The recent refugee crisis has put many Organisation for Economic Cooperation and Development (OECD) countries under considerable pressure to accommodate and integrate large numbers of refugees. Refugee students are a particularly vulnerable group due to their forced displacement, but their needs are not always met by education systems, which can hinder the integration potential of these students. This poses considerable challenges as the integration of refugee students in education systems is important for their academic outcomes as well as their social and emotional well-being. The success (or lack of) integration in schools can also affect the future labour market and social integration potential of these children and youth. While there is a growing body of research on the integration of immigrants, policy-relevant research on refugee children and youth from an educational perspective is rather limited, fragmented and case specific. Detailed surveys and research projects focusing on the current wave of refugees that allow for cross-country comparisons are not yet available. Drawing on research from previous refugee waves, the paper examines key needs of refugee students and factors that promote their integration. It proposes a holistic model of integration in education that responds to the learning, social and emotional needs of refugee students. Furthermore, the paper examines what type of policies and practices are in place in OECD countries that support the integration of refugee students. Nonetheless, evaluations of practices and policies are often missing, which makes it difficult to assess whether they are successful. The paper finishes with some policy pointers on how to promote the integration of refugee students.

This paper explores the impact of test-taking conditions on the quality of the Programme for the International Assessment of Adult Competencies (PIAAC) assessment. Interviewers record information about the room of assessment and interruptions that occurred during each interview. These observations, along with information on interviewer assignment size and a careful look at interviewer effects, provide insights into the quality of the assessment. This working paper first describes the variations in test-taking conditions among participating countries. Second, it examines interviewer assignment sizes and the frequency of interruptions, finding that both vary markedly among countries (contrary to the room of assessment). The paper then looks at the relationship between these variations and response rates and engagement measures. While neither the room of assessment nor the recorded interruptions impact quality differences among countries, interviewer assignment size and interviewer effects may have a mild impact on results.

This paper looks at the importance of mechanisms that give formal recognition to vocational skills acquired through work-based learning and how such mechanisms might be developed. It describes how skill recognition can benefit individuals, employers and society as a whole, and identifies in which contexts skill recognition has the highest potential to bring benefits. The focus is on three tools that are commonly used to shorten the path to a formal qualification: admission into a programme, reduced programme duration and qualification without a mandatory programme. For each of these tools, this paper sets out country approaches, discusses common challenges that arise in their implementation and advances policy messages to support policy design and implementation.

The opportunity to study abroad is broadly hailed as a route for young people to develop a wide range of knowledge and skills, including intercultural understanding, interpersonal skills, and language learning, among many others. Universities around the world are investing significant resources in developing a variety of study abroad programmes, ranging from short or long term in duration, and from guided to independent study. These may have a number of aims, including to promote individual student learning and development and to enhance student mobility and employability, particularly in the context of a rapid and changeable global employment market. The terms 'global citizen', 'global graduate', 'global skills' and 'global mindset' have all taken on increased significance within this context. Limited research has been conducted, however, to explore students' own perspectives of these terms. This small scale study therefore set out to explore the perspectives of students on UCL's BASc programme and especially to better understand where and how the learning they gained during study abroad resonates with UCL's global citizenship and student mobility strategies.

Numeracy and literacy skills have become increasingly important in modern labour markets. The large gender differences that several studies have identified have therefore sparked considerable attention among researchers and policy makers. Little is known about the moment in which such gaps emerge, how they evolve and if their evolution differs across countries. We use data from large-scale international assessments to follow representative samples of birth-cohorts over time, and analyse how gender gaps in numeracy and literacy evolve from age 10 to age 27. Our results suggest that, across the countries examined, males' advantage in numeracy is smallest at age 10 and largest at age 27. The growth in magnitude of the gender gap is particularly pronounced between the age of 15 and 27. Such evolution stands in sharp contrast with the evolution of the gender gap in literacy, which is small at age 10, large and in favour of females at age 15, and negligible by age 27.

This study uses the PIAAC data to examine the relationships between education system characteristics (e.g. early tracking and vocational education orientation) and distributions of adult numeracy skills. It also investigates the effects of postponing the tracking age and easing university access for students on a vocational track on the average skills and different percentiles of the skills distribution. Correlational analysis suggests that education systems with more students enrolled in vocational tracks have on average higher levels of numeracy skills and more compressed skills distributions between the 50th and 90th percentiles. Further analysis suggests that postponing the tracking age among 14 European countries does not have a significant effect on the average skills of the population. However, it increases skills for individuals at the 10th, 20th, and 30th percentiles of the skill distribution. Expanding university access is associated with an increase in numeracy skills, particularly for individuals at the bottom three deciles of the distribution.

Resilience refers to the capacity of individuals to prosper despite encountering adverse circumstances. This paper defines academic resilience as the ability of 15-year-old students from disadvantaged backgrounds to perform at a certain level in the Programme for International Student Assessment (PISA) in reading, mathematics and science that enables them to play an active role in their communities and prepares them to make the most of lifelong-learning opportunities. Using data from the most recent PISA cycles, this paper explores changes in the share of resilient students over time (2006-2015); highlights the importance of school environments and resources in mitigating the risk of low achievement for disadvantaged students; and identifies school-level factors that are associated with the likelihood of academic resilience among socio-economically disadvantaged students. Analyses reveal that several countries were able to increase the share of resilient students over time, reflecting improvements in the average performance of students, or a weaker relationship between socio-economic status and performance. In the vast majority of education systems examined, the likelihood of academic resilience among disadvantaged students is lower in schools where students report a negative classroom climate. The paper concludes by exploring school policies and practices that are associated with a positive classroom climate.

The paper examines between-country differences in the mechanisms through which education could promote generalised trust using data from 29 countries participating in the OECD's Survey of Adult Skills (PIAAC). Results indicate that education is strongly associated with generalised trust and that a large part of this association is mediated by individuals' literacy skills, income and occupational prestige. However, education gradients in levels of generalised trust and in the extent to which they are due to social stratification mechanisms or cognitive skills mechanisms vary across countries. Differences across countries in birthplace diversity and income inequality are correlated with how strongly education is associated with trust in different countries, as well as in the relative magnitude of direct and indirect associations. In particular, the relationship between literacy skills and generalised trust is stronger in the presence of greater birthplace diversity but is weaker in the presence of greater income inequality.

We assess the relationship between general literacy skills and health status by analysing data from the Programme for the International Assessment of Adult Competencies (PIAAC), an international survey of about 250,000 adults aged 16-65 years conducted by the Organisation for Economic Co-operation and Development (OECD) from 2011-15 in 33 countries/national sub-regions. Across countries, there seems to be a strong and consistent association between general literacy proficiency and self-rated poor health, independent of prior socio-economic status and income. General literacy proficiency also appears to be a mediator of the association between self-education and self-rated poor health. While the literacy-health association is robust over time, it varies in magnitude across countries. It is strongest for those with a tertiary or higher degree and does not appear to exist among young adults (ages 25 to 34 years). Future studies are required to understand the contextual factors that modify the general literacy proficiency-health association.

This paper presents a comprehensive analysis of the link between age and proficiency in information-processing skills, based on information drawn from the Survey of Adult Skills (PIAAC). The data reveal significant age-related differences in proficiencies, strongly suggesting that proficiency tends to "naturally" decline with age. Age differences in proficiency are, at first sight, substantial. On average across the OECD countries participating in PIAAC, adults aged 55 to 65 score some 30 points less than adults aged 25 to 34 on the PIAAC literacy scale, which is only slightly smaller than the score point difference between tertiary educated and less-than-upper-secondary educated individuals. However, despite their lower levels of proficiency, older individuals do not seem to suffer in terms of labour market outcomes. In particular, they generally earn higher wages, and much of the available empirical evidence suggests that they are not less productive than younger workers. Older and more experienced individuals seem therefore able to compensate the decline in information processing skills with the development of other skills, generally much more difficult to measure. On the other hand, proficiency in information-processing skills remain a strong determinant of important outcomes at all ages: this makes it important to better understand which factors are the most effective in preventing such age-related decline in proficiency, which does not occur to the same extent in all countries and for all individuals. Two broad interventions seem to be particularly promising in this respect. First, it is important to ensure that there is adequate and effective investment in skills development early in the life-cycle: as skills beget skills, starting off with a higher stock of human capital seems also to ensure smaller rates of proficiency decline. Second, it is equally important that policies are in place that provide incentives to individuals (and firms) to invest in skills across the entire working life. In this respect, changes in retirement policies can not only have the short-term effect of providing some reliefs to public finance, but have the potential to radically reshape incentives to stay active, to practice their skills and to invest more in training, thus helping to maintain high levels of proficiency. One table, Age Differences and Age Effects, is appended.

Using the 2012 PIAAC data, our analysis confirms that there are significantly higher earnings and employment returns to "both" increasing levels of formally recognised education, and to increasing levels of numeracy, literacy and information and communication technologies (ICT) skills proficiencies controlling for the level of education. Unsurprisingly, the labour market returns to changes in formally recognised levels of education in general exceed the labour market returns associated with increasing levels of skills proficiency. In the case of literacy and numeracy proficiencies, improved literacy and numeracy skills narrow the labour market outcomes gap between individuals with different levels of formally recognised education, but do not close it completely. The analysis demonstrates more substantial returns to ICT skills. Furthermore, possession of higher levels of ICT skills and lower levels of formally recognised qualification are often associated with higher returns compared to individuals with higher levels of formally recognised education but lower ICT proficiency levels. In other words, ICT skills proficiencies often entirely compensate for lower formally recognised qualifications in the labour market.
