This report presents data on the number of students affected by academic probation or dismissal during 1967-68 at California's institutions of higher education. Section A, the introduction, defines academic probation and academic dismissal. Section B discusses the academic probation and dismissal policies of the various campuses of the University of California and presents information on the number and class level of students affected by these policies. Section C does the same for the state colleges, and Section D for the community colleges. Section E discusses probation and dismissal on a statewide basis, and Section F presents the conclusions. The major conclusion is that a very large number of California students encounter academic difficulties and are placed on probation or dismissed, and that this is particularly true for students in their first term on campus. Appendix A discusses institutional policies that affect progress to graduation. Appendices B, C, and D present academic probation-dismissal statistics of the University of California, the state colleges, and the community colleges. A glossary of terms is given in Appendix E. (AF)
