This study assessed the effects of selected environmental factors on the post-high school adjustment of male Negroes from 12th-grade Project TALENT sample. Environmental influences were (1) Negro density in high school, (2) urban or rural school population, and (3) geographic region. Post-high school adjustment variables were (1) job stability, (2) job satisfaction, (3) number of jobs, (4) level of post-high school education, (5) planned post-high school education, and (6) rise of earning power. Data were collected from students tested in the 12th-grade in 1960 and their schools and from a 5-year followup questionnaire. It was found that (1) environmental-parameter could be distinguished from each other, (2) significant differences were generated by regional influences but not by community or Negro density factors; and (3) there were no significant environmental factors influencing post-high school education.
