The Peninsula Academies program operates two schools within schools, the electronics academy and the computer academy, in a three-year high school program for disadvantaged students labeled as potential dropouts in San Mateo County, California. A review of the performance of the Peninsula Academies program during its second year of operation (1982-83) showed that Academies students miss far fewer days of school than either their comparison group counterparts or students at their high schools as a whole. Mean scores and pass rates were also consistently higher for Academies students than for the non-Academy comparison groups on all three district proficiency tests--reading, mathematics, and written English. Academy students also had better grades and fewer "no credits" than their non-Academy comparison group counterparts. In addition, only 1 percent of Academy 10th-grade students dropped out of school this year compared to 8 percent of the comparison group. Attrition from the Academies program was significantly lower than last year. The survey data also presented a generally positive picture of the Academies this year. Students, parents, school personnel, and private industry representatives all gave the overall program high ratings. Recommendations were made for strengthening the program in the areas of clarification of the lines of responsibility for program management, better documentation of the computer laboratory curriculum, better inservice for the instructional staff, better definition of the target population, and more efforts at keeping parents informed.
