The second of three planned reports on 4-year outcomes for the 2,643 first-time students who entered Prince George's Community College (PGCC) in fall 1990, this document describes outcomes related to patterns of attendance and length of enrollment for various forms of academic achievement. Results of the analysis included the following: (1) between fall 1990 and spring 1991, 39% of the cohort failed to return, with another 17% failing to return by the next fall semester; (2) attrition, however, was found to be disproportionately high in the first two semesters, dropping off significantly in subsequent semesters; (3) of the 56% who attended more than 2 major terms, 34% enrolled consecutively, 15% stopped out occasionally, and 7% experienced major enrollment interruptions in the 4-year period; (4) 28% of all degree-seekers were classified as achievers after 8 major terms of study; (5) 96% of students with high persistence, good standing, sequential attendance, full-time study load, and not requiring remediation ended up as achievers; (6) on average, the cohort students spent 3.4 terms at PGCC; (7) it took sophomores a mean of 3.9 major terms to accumulate 30 credit hours; (8) students who graduated with associate degrees during the period enrolled in an average of 5.9 major terms; (9) full-time sophomores and non-developmental sophomores took one less term to collect 30 credit hours than part-timers; and (10) the time taken to transfer did not appear to be affected by study load and developmental placement.
