This report examines the findings from a series of evaluations of efficacy programs in selected elementary and middle schools in Peoria (Illinois), Detroit (Michigan), Los Angeles (California), and the Ravenswood School District in East Palo Alto (California). An efficacy program initiated in Sacramento is targeted as a research site, but no data are presently available. The research conducted in Peoria, Detroit, and Los Angeles investigates the effects of these programs on various outcome measures, both qualitative and quantitative, including improvement in students' grades, decreases in absenteeism, attitude changes toward school work, and performance on standardized achievement tests. Findings indicate that elementary and middle school students who participated in the efficacy programs made significant gains in their achievement. In addition, teachers report positive perceptions of the program and cited the need to expand and continue the program for all grade levels. Thirteen tables provide program data.
