The purpose of this study was to determine the effects of a peer-taught freshman seminar course on the grade point averages and retention rates of freshman students. Freshman students who entered the University of Texas at Arlington in the fall 1989 and fall 1990 semesters and enrolled in the voluntary 1 credit hour course "College Adjustment" were matched with freshman students who did not enroll in the course. Matched pairs were formed based on orientation attendance, college major, gender, and Scholastic Aptitude Test (SAT) scores. For both years, the Freshman Seminar Group was similar to the group of All Other Freshman Students regarding the following characteristics: college major, age, gender, ethnicity, SAT scores, and number of first semester hours completed. Analysis of variance was used to determine if statistically significant (p < .05) differences existed between the first semester and first year grade point averages for the Freshman Seminar Group and Freshman Seminar Matches. Chi-square analysis was employed to determine if statistically significant (p < .05) differences existed between the second semester and sophomore year retention rates for the Freshman Seminar Group and Freshman Seminar Matches. The freshman seminar course was more beneficial to African American students, as evidenced by statistically significant first year grade point averages and sophomore year retention rates. Males who enrolled in the freshman seminar course appeared to benefit more than males who did not enroll in the course, as shown by statistically significant sophomore year retention rates. Students with low SAT scores appeared to benefit from the freshman seminar course, as evidenced by statistically significant second semester and sophomore year retention rates.
