This report is a series on the Program of Special Directed Studies for Transition to College (PSDS), which is a five-year experimental education project aimed at providing a full four-year high-quality college education for disadvantaged youths who would probably not otherwise have been eligible for admission to most four-year colleges. A research and evaluation program planned as an intrinsic part of the experimental project encompassed a pre-test and post-test control-group design to provide analyses of test score changes as well as of comparisons with scores of other students. The test battery included: (1) questionnaire measures of demographic variables, family background, and attitudes toward college and the PSDS program, and (2) standardized and experimental measures of personality and motivational variables such as self esteem, social adjustment, interests, expectations, and values. A success rate of over 50% of PSDS students was claimed as a result of examination of general data on success. The attitudes, values, and personality traits of PSDA students were shown to be remarkably similar to those of more advantaged "typical" Claremont College students, and the ability of the former students to compete successfully with the latter was also held to be equally remarkable.
