A survey was conducted of 1,343 community college students who transferred to the University of California, Los Angeles (UCLA), in fall 1977 to determine the major factors influencing student withdrawal or persistence. In addition to requesting information on students' background, the survey questionnaire asked the students to contrast their community college and UCLA experiences with respect to several measures, including: (1) students' writing experiences and activities; (2) their use of the library; (3) their participation and learning experiences in class; (4) their contact with the faculty; (5) gains made in their ability to think critically and quantitatively, to find and synthesize information, and to appreciate the arts; and (6) environmental factors, such as intellectual, aesthetic, critical, and vocational emphases and student-teacher relations. Regression analyses were performed to establish the relationship between these independent variables and two dependent variables--UCLA grade point average (GPA) and persistence or withdrawal as determined by spring 1979 registration status. Survey responses from 508 persisting students and 316 dropouts revealed that persistence and GPA were significantly related to transfer GPA, unmet financial needs, writing experience in the community college, and selected majors. The study report contrasts transfer and native students and persistors and dropouts and includes the questionnaire. (HB)
