This document analyzes the extent to which the four community colleges in the Peralta district (California) have been successful in terms of student outcomes. Student success is defined as the percentage of successful course completions as compared to unsuccessful course completions. This document looks at the period from the fall of 1993 through the fall of 1998. At all of the community colleges in this report, those students who had already completed an associate's degree or higher, were the most successful. Similarly, students who had graduated or attended a foreign high school were also among the most successful students. Moderately successful students were those who recently graduated from high school, returning students, and returning transfer students. Those who did not have a high school diploma and those who had completed the GED or high school equivalency/proficiency were among the least successful students. Students under 16 years of age do comparatively better than their slightly older counter parts, but in general older students tend to be more successful than younger students at all four of the community colleges. The report goes on to compare student success by using other demographic variables such as ethnicity, gender, and graduation status. (TGO)
