Research by Sara Goldrick-Rab and Fabian T. Pfeffer (Sociology of Education, April 2009) using data from the National Education Longitudinal Study indicates that approximately one third of traditional-aged college students transfer from one college to another within eight years of high school graduation. Only 6 percent transfer from community colleges to four-year colleges, while 15 percent will “reverse transfer” from four-year colleges to community colleges. According to the authors, reverse transfers are more likely among students from disadvantaged socioeconomic backgrounds.
