Evidence on school size, however, is mixed as to its effect on college attendance. Borus and Carpenter (1984) found that high school seniors attending schools with between 1000 to 1749 students to be more likely than those attending schools with over 1749 students to attend college. However, no difference between students attending schools with fewer than 1000 students and schools with over 1749 students. Another study found that adolescents from larger schools were more likely to drop out of high school than those from smaller schools (Marsh, 1991b).
