Drawing from Miami-Dade Community College's computer file containing over 60,000 student records, this report presents data on six student cohort groups entering the college as first-time-in-college, full-time students between fall 1976 and fall 1981. For the college as a whole, and for each of its four campuses, longitudinal data are provided on student ethnic background, gender, and age, and re-enrollment and graduation rates. Selected findings include the following: (1) each of the student cohorts contains over 5,000 full-time students, representing approximately 50% of the total first-time-in-college students; (2) the male to female proportions have shifted over the 6-year period, so that slightly more than half of the students in each cohort are females; (3) the ethnic proportions have also shifted across the years, with an increase in the proportion of Hispanic students evident; (4) for both Blacks and Hispanics, the proportion of students over 26 years of age has gradually increased; (5) in general, after 3 years, 25% of the students remain enrolled and 25% have graduated; and (6) the implementation of standards of academic progress in 1978 had an initial effect of depressing re-enrollment and graduation rates among all ethnic groups, though a recovery in these rates was evident in later cohorts among White and Black students. The report concludes with questions for further research. (HB)
