As part of an effort by William Rainey Harper College (WRHC) to determine the educational needs of minorities on campus and in the community, a study was conducted of the academic performance of different ethnic groups. Using student transcripts, the longitudinal performances of 100-student samples each of Blacks, Asians, and Hispanics were analyzed for the period between 1976 and 1984, and compared with results from similar studies done on samples of the entire, 90% White, student body. Study findings included the following: (1) overall, Whites earned a higher grade point average (GPA) at WRHC, averaging 2.53, compared to 2.44 for Asians, 2.14 for Hispanics, and 1.98 for Blacks; (2) females earned a higher average GPA than males in all ethnic groups except for Hispanics; (3) 90% of the Asian students, 84% of the Hispanics, 70% of the Blacks, and 60% of the Whites returned to WRHC after their first year of enrollment; (4) in terms of semesters attended, Asians averaged 6.7 semesters, Hispanics 6.3 semesters, Blacks 4.9 semesters, and Whites 4.0 semesters; (5) 22% of the Black students transferred credits from other colleges into WRHC, compared to only 9% of the other students; (6) minorities were more likely to take continuing education courses along with their degree credit courses than were Whites; (7) 44% of the Hispanic students and 36% of the Asian students enrolled in adult educational development or English-as-a-Second-Language courses, compared to only 7% to 9% of the Black and White students; and (8) there were only small age differences across the ethnic groups.
