The match between a student’s academic ability and the academic ability of the student’s peers has been found to exert influence on student educational aspirations. Research on this has garnered mixed results with some finding that students whose peers have higher ability are more likely to develop a poor self-concept and lower their academic aspirations and others finding the opposite, that more able peer increase motivation and aspirations overall. While the effects of peer and student ability match on the educational aspirations of elementary and secondary students have received attention in recent years, these effects have largely been neglected in postsecondary education. In this study, I use recent postsecondary student data to see how the difference between the student’s SAT score and the mean institutional SAT affects the likelihood of the student experiencing a decrease in educational aspirations post college entry. Findings indicate that students whose scores are below the mean institutional SAT and who are attending less selective institutions are more likely to experience a decrease in future educational aspirations post college entry than students whose SAT scores are above the mean. However, students attending more selective institutions are protected from this effect, likely because of greater selection in admissions at more selective postsecondary institutions.
