The Gilroy, California, Unified School District contracted with Westinghouse Learning Corporation for the 1970-71 school year for the purpose of improving reading and mathematics achievement of approximately 100 Spanish-surnamed boys and girls from grades 2-4. The average gain at the end of the program was 0.6 achievement years in reading and 0.8 achievement years in mathematics, well below the expected two-year gain. An analysis of nonacademic results, however, revealed that: (1) Students generally enjoyed the program; (2) There was no observable effect of the program on student attendance; (3) 48 out of 53 parents indicated their approval of the program. The author indicates performance contracting acted as an agent for positive change. Teachers are more concerned with diagnosing a child's performance in relation to the skills he needs to develop, and then prescribing for him an instructional curriculum that is specific to his individual needs.
