This paper reports on three projects in California that have attempted to stem the tide of Latino dropouts and increase the college-going rates of the Latino population. Each of these three programs has tested a set of strategies aimed at increasing the educational attainment of Latino students, who now make up the largest single ethnic group in California's public schools. They also have the highest dropout rate of any of the state's ethnic groups. The educational attainment of all Latinos is significantly lower than that of other ethnic groups in the United States as well as in California. The first program, Achievement for Latinos through Academic Success (ALAS), was a demonstration program that targeted the lowest achieving Latino students with the greatest risk of dropping out of high school. Because these students are considered comprehensively at risk, the program used a comprehensive approach to address the needs of families as well as students. ALAS was piloted at the middle school level. The second program, Advancement Via Individual Achievement (AVID), continues to target academically underachieving students with above-average test scores at the high school level. It attempts to move them into a college preparatory educational track. The focus is directly on students, most of whom are from lower income communities. The third program, Puente, targets students who are more generally at risk for reasons such as attending high schools where small percentages of students go on to college and where social problems commonly derail students' academic aspirations. Puente includes students along nearly the entire continuum of academic achievement with the aim of ensuring that they complete high school and go on to college. These three programs were all designed to plug leaks in the educational pipeline for Latinos. AVID and Puente continue to expand in California schools, but the funding has ended for the ALAS demonstration project. (Contains 20 figures, 14 tables, and 102 references.) (SLD)
