This followup study of the field test and evaluation of selected adult basic education systems was begun in July 1966 and carried out in California, New Jersey, and New York, where the earlier study had been held. The study focused on the impact which the field test and other education and/or training programs had on the participants in terms of educational gain and retention, social awareness and functioning, and economic improvement. Testing and retesting six and 12 months after the field test provided data on over 1,600 persons. Other data were obtained through in-depth interviews with field test participants and teachers, nonparticipant welfare recipients, and personnel of various agencies. Findings on academic achievement, employment, income, welfare grants, interagency cooperation, and attitudes toward involvement in the programs reinforced the results of the original field test with respect to the need for education and training for the functionally illiterate, and the necessity to upgrade and improve all aspects of adult basic education, including curriculums, teacher training, materials, and supportive services.
