The study attempted to measure world-of-work values and perceptions at entry and after a period of employment of enrollees in Plan D of the Public Service Careers (PSC) Program, a Federal program designed to bring disadvantaged individuals into Federal employment. A PSC Enrollee Questionnaire, developed from a logical taxonomy of world-of-work values based on an extensive review of related literature, was administered twice, along with supervisor evaluations, for initial testing and at six months after employment. The first session involved 328 enrollees in the entry-level component, 106 individuals in the upgrade component, and 95 Federal employees holding equivalent positions to those of PSC entry-level workers. The second session involved 211 PSC entry-level enrollees and 137 of their supervisors. Project background, methodology, data analysis, summary of findings and recommendations are presented, with 27 tables. Appended material, encompassing half the document, presents the data collecting instruments and responses. Conclusions state that PSC enrollee perceptions of world-of-work values were congruent with the "middle-class value system", these values were maintained through job experience, and the PSC employee is generally underemployed in the entry job and might continue to be after one promotion.
