This monograph reviews the literature on intervention for potential dropouts at the secondary school level in order to determine factors responsible for students being at risk and to provide information on a variety of projects and programs that are effectively alleviating the number of such students who fail to complete their education. The review found that what works for retaining potential dropouts at the secondary school level is as varied as the communities in which the students live. However, effective programs are usually doing the following: (1) providing various kinds of programs that improve students' skills in reading, writing, and mathematics; (2) creating an environment that is conducive to students' sense of belonging to their school and sharing the decision and policy-making procedures; (3) identifying students who do not participate in school activities and encouraging their involvement; (4) making counseling services available and accessible; (5) maintaining small classes in which students participate in cooperative sharing activities with other students and instructors; (6) offering opportunities for students to socially interact with responsible adult role models; (7) providing alternative programs and settings outside the regular academic environment; and (8) teaching job-related skills and basic skills in reading, writing, and mathematics concurrently. Included are 20 references. (JB)
