In 1969, 790 questionnaires in four languages (Arabic, English, French, and Spanish) was sent to all governmental and non-governmental organizations to obtain details of methods and techniques used in adult literacy projects. The replies of 74 organizations in 52 countries, with a total of 100 projects and 133 courses, are included in this report. The seven categories into which the replies are categorized are: organization, programs (courses), methods and teaching aids, materials, participants, drop-outs, and instructors. The replies are discussed and presented in statistical tables and graphs. Examples of instructional materials used in some of the projects are included. Conclusions reached include (1) greater interest by the governments would aid considerably in solving project problems; (2) the literacy level attained in most projects is too low to prevent relapse into illiteracy; (3) large classes are more effective than small ones and also decrease the number of instructors needed; (4) a gradual transition from traditional to functional literacy programs is desirable, with training of instructors and seminars for project planners a concomitant necessity; (5) the high rate of drop-out shows a need to study prospective participants; and (6) systematic studies and experiments should be undertaken in various cultures. Annex I is a copy of the questionnaire; Annex II are names and addresses of the respondents; and Annex III is a tabulation of the replies. (DB)
