During the 1970-71 school year, the Grand Rapids, Michigan, School District had performance contracts for reading and math instruction with Alpha Learning Systems, Inc. (Alpha), Combined Motivation Education System, Inc. (CMES), and Westinghouse Learning Corporation (WLC). The programs of all three contractors featured contingency management and individualized instruction, and all used commercially available materials and equipment. The WLC program accommodated 340 low achievers in two inner city schools in grades 1-6. The CMES program accommodated around 550 low-achieving pupils in an inner city middle school, grades 6-9. Both of these programs had rooms furnished much more comfortably than regular classrooms. The Alpha program accommodated 300 low achievers in a middle school in grades 7-9 and 300 low achievers in two elementary schools in grades 1-3. All schools were in the inner city. Average achievement gains in the WLC program for pupils who attended at least 150 days were 0.67 in reading and 0.58 in math. The average gains in the CMES program for pupils who attended at least 150 days were 1.2 in reading and 1.0 in math. Achievement data for the Alpha program were not available at the time of this publication. The Grand Rapids experience underscores the value of performance contracting as an agent for introducing instructional innovations. For related documents, see ED 056 247, 248, 249, 250, and 251.
