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. This study compared CSMP and non-CSMP students' performance at two sites using a streamlined revision of the Mathematics Applied to Novel Situations (MANS) test, with 10 program and 8 non-program classes examined. On 10 of 15 individual scales, CSMP classes scored significantly higher at the .05 level, and on 5 of those 10 at the .01 level. On the total of the MANS scales, CSMP classes averaged about 19 percent higher, a difference significant at the .01 level. The findings are seen to corroborate the results from more extended testing covered prior to the revisions. Results are also viewed as noteworthy because the simplification of testing procedures makes the evaluation easier for other districts to use and still leaves scales powerful enough to show various cognitive effects of the CSMP curriculum.
