The impact of basic skill developmental programs on student success in career programs was investigated. Data collected from 61 two-year institutions provided the basis for selection of six survey sites. At each site, random samples of students in their initial enrollment in developmental programs, students previously enrolled in developmental studies, and students never enrolled in developmental studies filled out questionnaires, standardized instruments, and participated in in-person interviews. Success or non-success of developmental students was defined for study purposes as academic eligibility to continue in a study program. Findings indicated that developmental programs with the greatest impact were those with sufficient flexibility to give students individual attention. Successful students valued goal orientation and recognition more highly than non-successful students. Success appeared related to students' conformity and negatively to their value of variety. The question of student commitment also emerged as significant. Successful students exhibited firm career goals, and their program choices were based on personal inclination rather than external influences. Guide questions in six program areas were developed on the basis of the findings to assist counselors in identifying local program standards for developmental studies. (TR)
