Project MACK's major goal was to provide a comprehensive school program at McClymonds High School in Oakland, California that would reduce the dropout rate, improve student achievement, reduce absenteeism and class-cutting, and improve student attitudes toward school. Project components included 1) Career Cluster Program, which focused on work experience and classroom occupational orientation, language arts, social studies, reading and math workshops, inservice training, and the instructional media center; 2) Student Support Services, which provided guidance and counseling, special psychological services, a health program, a student activities program, and inservice training; and 3) a Management Component, which provided for overall coordination of the project. Project MACK was successful in reducing the percentage of dropouts from 16.1 percent to 6.2 percent. There was a reduction in the class-cutting rate from 23.0 percent in 1970 to 7.2 percent at the end of 1974-75. The absentee rate was reduced by 14.1 percent. Reading and mathematics achievement test scores of students who enrolled in Project MACK's reading and math programs showed significat gains. Surveys showed that a majority of students and parents were satisfied with the progress made by the project. (Author/JG)
