At Hudson County Community College (HCCC), in New Jersey, research on student attrition has included cohort specific studies of enrollment and completion patterns, enrollment pattern studies of instructional programs, and periodic surveys of enrolled students, former students, and graduates. A comparative analysis conducted of previous attrition research at HCCC revealed the following: (1) for 1989 entrants, the 1-year retention rate of full-time first-time students was 42%, up from 36% in 1987 and 1988; (2) the comparable retention rate for African American and Hispanic students among fall 1989 entrants was 37%; (3) in both 1984 and 1990, the culinary arts program showed the highest 1-year retention rate; (4) students admitted from 1983 to 1985 through the Educational Opportunity Fund program had lower retention rates than regularly admitted students, though their retention rates had improved dramatically by 1989; (5) overall, full-time students had higher retention rates than part-time students; and (6) the numbers of students transferring to senior institutions in New Jersey increased between 1987 and 1989. In addition to instituting more systematic studies of enrolled students, former students and graduates, HCCC will be conducting an in-depth study of enrollment, leaving, and completion patterns for selected cohorts of students who entered each term beginning in 1986. These cohorts will include both part-time and full-time students in English as a Second Language, basic skills, and full-degree-credit programs. A list of previous retention studies, detailed data tables, and a copy of a revised graduate follow-up survey are included. (PAA)
