This document presents a study of the effectiveness of the Job Training Partnership Act program Project STAY, designed to impact the dropout problem in Stockton, California area high schools. A literature review discusses dropout characteristics, schools that dropouts leave, employment opportunities for the general population and for dropouts, personal consequences of dropping out, economic risk to California from dropouts, the cost of illiteracy, and the Job Training Partnership Act. The methodology of the study is explained. Results are discussed in terms of demographics, grade point average and attendance correlation, overage correlation, competencies mastery, age/career maturity correlation, job placement percentage, academic credit demographics, and a 1984-85 follow-up study. It is concluded that the program failed to effect long-term dropout prevention but was successful in teaching job readiness skills. The appendices include students' training tests, statistical results of the study, and program descriptions. (ABL)
