An investigation was conducted at Prince George's Community College to determine Fall 1980 course passing rates within college divisions and departments; passing rates and grade distributions in courses using different modes of instruction; within-term course withdrawal rates; term-to-term retention and attrition rates; students' reasons for college withdrawal; and the number of students diagnosed as needing developmental study. Data analyses revealed that: (1) the college-wide passing rate was 71%, representing a 1% drop from the passing rates of the previous three fall semesters; (2) health technology and physical education classes continued to have high passing rates, and science and math courses again had the lowest rates; (3) compared to Fall 1979, 13 departments had improved student success rates and 24 departments had lower success rates; (4) in most disciplines, introductory courses had lower passing rates; (5) eight-week courses and courses using audio-tutorial instruction had passing rates above the college average, while telecredit courses and courses using the Personalized System of Instruction had lower passing rates; (6) 14% of all course enrollees withdrew during Fall 1980; (7) the most frequently cited reasons for leaving the college were work conflict and academic difficulty; and (8) two-thirds of the Fall 1980 enrollees returned for Spring 1981. Fifteen data tables, in many cases revealing trends over several years, are appended. (Author/AYC)
