The principal aims of this study were to identify, select, analyze, and describe educational programs for culturally disadvantaged children from preschool through grade 12 which had yielded measured benefits of cognitive achievement. A literature search (mainly through ERIC) and mail inquiries followed by telephone consultations constituted the identification and selection process for the programs. Sixteen programs finally selected (situated in 12 urban areas in eight states) were visited on site, and as a result, five programs were eliminated. This report thus contains the descriptions of the remaining 11 programs, all meeting the criteria that no program was included unless data available indicated that pupils in the program had achieved statistically significantly greater gains on standardized tests than had controls, or had improved at a rate better than national norms. Programs described were mostly inner-city projects for black children, but two served mainly Mexican-Americans; descriptions relate to the nature, operation, and results of each program. The report also includes detailed descriptions of the methods and procedures employed in the study. For earlier studies of 21 similar programs in two sections, Parts I and II, see ED 023 776 and ED 023 777, respectively. Programs described in the present report are also individually reported; see UD 010 069 to-078, and 010 114. (RJ)
