Report I is designed to provide a statistical profile of the 32 Community Colleges participating in the study of Persistence and Performance in California's Community Colleges, using data available in the student accounting reports made annually to the Office of the Chancellor by the California Community Colleges. No attempt was made to go beyond the data included in these reports. The findings show quite clearly the diversity that exists among the 32 colleges, as well as the heterogeniety of the students enrolled in them. Additional information about the colleges will be presented in subsequent reports, which will be useful in interpreting differences among student bodies, in both their persistence and performance. The study is thus the story of a representative group of 32 colleges, as well as the story of more than 32,000 students. Data for the following are tabulated for the first report: (1) total enrollments by college; percentages in credit classes by class level and percentages in noncredit classes; (2) enrollments in day and evening credit classes; (3) enrollment status of freshmen, sophomores, and other students in credit classes; (4) first-time freshmen, day and evening, by location of high school last attended; (5) first-time transfer students, day and evening, by type of institution of origin; and (6) summary of credit and noncredit students by age, sex, and enrollment category. Data are for fall 1972 or 1971 and 1972. (For related document, see JC 740 041). (Author/KM)
