This 22-country survey was conducted between 1994 and 1998. Representative samples of adults aged 16-65 were interviewed and tested at home using the same literacy tests. The main purpose of the survey was to find out how well adults use information to function in society. Another aim was to investigate the factors that influence literacy proficiency and to compare these between countries. Ten international indicators are presented that allow readers to compare the literary proficiency of Americans with that of other populations as measured on the prose literary scale; similar results are provided in quantitative scales. The findings confirm how low literacy is an important issue in all regions in all countries surveyed. On the whole, the findings show that Americans are at an average level of prose literacy performance, behind the Nordic countries and the Netherlands but on a par with adults in Australia, Canada, and Germany. Literacy proficiency is more unequally distributed in the United States and Canada than in Europe, with the most literate 25% of North Americans scoring far higher than average. "Life-long" learning programs, as well as early childhood education, more access to adult education and to information and communication technologies, and the promotion of literacy-rich environments at work, home, and in the community are proposed as solutions to improve adult literacy. The paper is divided into 3 chapters, 4 annexes, and 10 data-rich figures. (Adjunct ERIC Clearinghouse for ESL Literacy Education) (KFT)
