Data from the College Entrance Examination Board's Comparative Guidance and Placement (CGP) Program were used in these two studies of students at Central Virginia Community College (CVCC). In the first study, 1971 fall quarter performance in specific courses and in all courses was compared to CGP performance. The conclusions indicate that: (1) CGP scores in general are related to overall success in college course work; and (2) it is reasonable to use CGP performance as a predictor of specific course and overall success. The second study compared the ability (as measured by the CGP scores) of CVCC students, students in the Virginia Community College System, and students in all public comprehensive junior colleges for fall of 1970 and 1971, to help determine the academic progress of students at CVCC. There appears to be a clear difference in ability at entrance among community college students at the three levels (local, state, and national). For most of the subtests, CVCC students scored higher than the state junior college students, and the state group scored higher in ability than the national group. (RN)
