A study designed to assess the academic performance of native and transfer students in the upper division of the University of Florida was launched to analyze and compare grade point averages, attrition rates, and progress towards graduation of various groups admitted to the program and to determine whether previous academic performance is related to performance at that institution. "Native" students were those admitted to the upper division after completing two years in the University College of the University of Florida; "transfer" students were those who completed two years at Florida public junior colleges or elsewhere. Native students made better grades in the upper division, had a lower attrition rate, and progressed more rapidly towards graduation than did the transfer students. (Author/MS)
