In order to study transfer trends in Maryland, a method was developed for matching student records at two-year sending institutions and four-year receiving institutions in the state. Transfer matrices, which utilized the computerized fall enrollment records of all public two- and four-year institutions in Maryland, allowed for a campus-to-campus match for all students, as well as for specific groups of students, such as minority, transfer and career program, and full- and part-time enrollees. Both the fall-to-fall movement of students from one campus to another, and the outcomes for cohorts of students four and seven years after entry were examined. Analyses of the data revealed the following: (1) the number of undergraduate students transferring from two- to four-year institutions in Maryland has remained stable over the last six years, with approximately 3,100 full-time and 2,765 part-time students transferring each year; (2) between 1983-84 and 1988-89, the number of full-time black student transfers decreased by 21%; (3) 24% of the students who transferred in 1988-89 were enrolled in career programs at the two-year institution; (4) policies limiting the numbers of students at one four-year institution led to increases in student transfers to other institutions in the state; and (5) between 7% and 8% of entering community college cohorts transferred to four-year schools after earning a community college degree. Data tables, sample matrices, and a detailed discussion of the application and uses of the research methodology are included. (PAA)
