An assessment model was developed to produce change in adult basic education (ABE) programs and thereby improve learning for adult students. During the development of the model, 89 ABE programs were analyzed. To determine the effect that ABE has on the quality of life of its students, researchers observed 77 of the 89 programs included in the study and administered questionnaires to 1,625 students who could be described as being predominately white, female, less than 30 years old, and earning less than $10,000 per year. In essence, the assessment model developed calls for: (1) observation of program planning and objectives, program organization, classroom interaction among students and teachers, and student perceptions; (2) analysis of these four factors to determine appropriate elements for change; and (3) development of strategies for improved teaching and learning. Data collected indicated that goals and objectives were not consistent across programs that are within a given geographic area and that are funded by the same source; however, the ABE programs are having a positive impact on students' quality of life, with males, older adults, and those who have been in ABE longer having the most positive attitudes toward the program. (This description of the model includes 41 tables, 10 charts, and a flowchart depicting the assessment model.) (MN)
