In 1969 800 questionnaires were sent in four languages to governmental and non-governmental agencies dealing directly with adult literacy in 123 countries. The purpose was to receive details on methods and techniques used. Only 80 replies were received, 73 of which provided information for the study. Replies were classified in seven main categories: organization; programs (courses); methods; materials; participants; dropout; and instructors. Emphasis is laid on the aspect of dropout. The dropout rate has been discussed and analyzed according to the factors that affect it: duration of course; content of the course; responsibility for the payment for educative materials; teacher's salary; implementation of radio and television as a teaching aid; and time of the start of the project. The last part of the document is devoted to tables that contain information on the seven main categories of replies. Further statistical work will be done and interesting details will be reported in the final report. (PT)
