Data collected in a longitudinal study made to determine the academic performance of Missour junior/community college transfer students during a four-semester period at the University of Missour-Kansas City are presented in tables. The data are divided into three areas of the transfer pattern: academic entry pattern, including GPA by group, sex, semester, and transfer shock; the attrition pattern; and the persistence pattern by academic division, sex, and age. The data are based on 235 students who transferred from six Missouri junior colleges in the fall of 1971, and completed at least the fall semester. Individual student files, student transcripts, and the Data Processing Center at the university were the data sources. Students were divided into four groups, based on their number of transfer hours. Results of the study showed that by the spring of 1973, 66 students from the original transfer population had earned B.A. degrees. Of the 76 students who transferred from the junior colleges with an A.A. degree, 31 students (41 percent) earned the B.A. degree by the spring of 1973. (DB)
