Professionalism is an important issue for FE policymakers in post-16 education because of its established links to competence, morale and staff continuity. This study examined concepts of professionalism in the English further education sector, how it is strengthened or weakened, and the implications this has for workforce planning and management. The study adopted a Bourdieusian framework which explains social phenomena such as professionalism in terms of three capitals (social, economic, cultural). These capitals operate dynamically in a social structure (field) and generate potentialities for social thought and action (habitus). The study utilised a survey comprising quantitative and qualitative forms of enquiry to investigate both structural and attitudinal aspects of professionalism. The survey contained six sections: demographics, employment, subject knowledge, work relationships, motivation and professionalism. Perceptions of professionalism were measured using a revised 15-item version of the Hall professionalism scale (1968) based on adaptations by Wimmer (2007) and Scailes (2003). Measures of cultural, social and economic capital were also constructed. An online survey was sent out to teachers, managers and curriculum support staff working across the sector with 461 useable responses collected. The achieved sample reflected the sector profile in terms of gender, ethnicity and background, though the average age was slightly higher in the achieved sample. The quantitative data was analysed using descriptive and inferential methods including exploratory factor analysis, regression, ANOVA and correspondence analysis. Professionalism was affected by key respondent demographics and occupational position. Professionalism was also found to be statistically significantly related to the distribution of capital (cultural, social and economic). A typology highlighted the way in which the three capitals were distributed in the sample. The data yielded three overarching themes for FE professionalism: expertise, service and organisational compliance. Respondents’ location in the FE hierarchy determined which of these themes were perceived as dominant. Of the three themes, expertise was the most important variable differentiating scores on professionalism and work status, but to function as capital it must be recognised by others. This study has demonstrated that professionalism is a more nuanced concept than previous studies have suggested. In FE, notions of professionalism vary across the FE field according to job role, committee membership, trade union membership, teaching load and incidences of non-specialist teaching. The findings establish a relationship between people’s position in the field and the way capital is distributed. There is also further evidence, in line with recent analyses by Lobb (2017) and Donovan (2019), that professionalism in FE is being challenged by persistent managerial pressures.
