This study is principally concerned with examining the upper-division academic achievement of "transfer" students (those who entered the UW from both the 2-year community colleges) and of "native" students (those who entered the UW directly from high school). Only students who, in Autumn 1968, had earned between 80 and 100 quarter credit hours (approximately junior level) were included in the above study groups. In general, the findings are as follows: (1) Over a common 5-year period of possible upper division attendance, native students have a markedly higher UW graduation rate than have transfer students from either the 2-year or 4-year colleges; (2) When compared on upper division GPA earned between 1968 and 1971, native students significantly outperform 4-year transfer students, who, in turn, significantly outperform 2-year transfer students; (3) Among those who withdraw from upper-division programs, grades are very low for those dropping out early (most pronounced for transfer students) but quite adequate for those dropping out late, and (4) A supplemental analysis was conducted on native and transfer groups who, as of Autumn 1967, had previously earned between 35 and 55 quarter credit hours (approximate sophomore level). This analysis revealed the same achievement trends as observed for the junior-level groups (and therefore are not included in this report) except that the community college students fared relatively worse than the other comparison groups both in graduation rate and post-transfer grades.
