Despite recent efforts to provide equal education, agreement exists that blacks, females, and disadvantaged students as a group are outperformed in mathematics and science by white middle-class students. To help disadvantaged students, the Duval County Public Schools (Jacksonville, Florida) have developed a "Mayo Clinic" approach to education that treats students as individuals with unique circumstances. This paper summarizes successful features of the program and evaluates its progress. Duval eliminated social promotion factors by implementing a plan requiring students to master specific competencies before progressing to the next grade level. To address the gap between black and white students' Scholastic Aptitude Test scores, the Stimulating Aptitude Skills project was developed. Students electing to participate in the test preparation program were evaluated to determine particular deficiency areas, and an instructional program was developed based on the diagnosis. Black students taking the course scored significantly higher on the SAT. The program is also useful in identifying and assisting potential dropouts and retrieving school leavers. The biggest project to emerge from the gap study is Project BASE (Blacks for Academic Success in Education), which involves parents, churches, and businesses in helping students adopt beneficial lifestyle changes. The program has succeeded in changing teachers' attitudes, expectations, and instructional approaches. Black students' achievement gains continue to be remarkable, and more are joining Project BASE each year. (MLH)
