The Comprehensive School Mathematics Program (CSMP) is a program of CEMREL, Inc., one of the national educational laboratories, and was funded by the National Institute of Education (NIE). Its major purpose is the development of curriculum materials for kindergarten through grade 6. One of the most important questions in the evaluation of CSMP is whether the transition to junior high school mathematics is made easier or more difficult because of pupil experience with the program. This study is a preliminary investigation, a comparison of seventh-grade mathematics teachers' ratings of former CSMP versus non-CSMP students' performance in class. The summary notes the data are far from definitive, but former CSMP students seen to be doing at least as well in seventh-grade classes as students from standard programs. Three sites were examined where comparison between non-CSMP and CSMP pupils was possible. At two of these sites, former CSMP pupils received higher teacher ratings for participation in class, motivation, creativity and problem solving, and practical applications. There were no differences between th two groups at a third site. (MP)
