The first 15 pages of the manual provide: (1) background information on the importance of adult education, the need for adult education statistics, the International Standard Classification of Education (ISCED), and the scope of the term adult education; (2) the application of ISCED to adult education and the ISCED classifications (levels, fields, and programs); and (3) the need for national statistical services for adult education with suggested organizational forms and data collection, processing, analysis, and publication techniques. The remainder of the document consists of three appendixes. Appendix A (13 pages) suggests the type of questionnaire and instructions that national statistical offices might wish to send to the parent agencies which organize programs of formal adult education. Appendix B (12 pages) suggests the type of questionnaire and instructions that national statistical offices might wish to send to parent agencies which organize programs of nonformal adult education. Appendix C (21 pages) defines with respect to scope and meaning the various terms used in ISCED. (Author/JR)
