A study was done of the success of the San Diego (California) public school detracking program, Advancement Via Individual Determination (AVID), by measuring the students' college enrollment. The AVID program was developed as an alternative to compensatory education and remedial tracking for underachieving high school students, especially those from ethnic and linguistic minority backgrounds. The program placed low- and high-achieving students together in a rigorous academic program while providing students with strong social and academic supports. In particular, one academic period a day was devoted to AVID activities taught by a coordinator trained in collaborative teaching methods, inquiry approaches, and writing-to-learn techniques. The coordinator and aides provided the students with tutorial assistance in their academic subjects. Interviews were conducted with 144 AVID graduates from the classes of 1990 and 1991. Of the participants, 41 percent were Hispanic American, 12 percent were White, 28 percent were African American, and the remaining were of other minority groups. The findings reveal that 50 percent were enrolled in four-year colleges. The local average for four-year college enrollment was 38 percent and the national average was 39 percent. Included are 2 tables, 12 bar graphs, and 48 references. (JB)
