Investigated were differences between levels of achievement of freshmen general chemistry students as related to high school chemistry curricula. Objectives of the study were: (1) to measure the degree of success achieved by college general chemistry students related to their high school chemistry curricula, (2) to evaluate CHEM Study as related to the needs of the average student, and (3) to determine recommendations for achieving the goals of science education at both secondary and college levels. The testing instrument was the 1970 form of the American Chemical Society general chemistry achievement test. Participants included representatives from high schools using both traditional and CHEM Study programs. A statistically significant difference existed at the .01 level between the CHEM Study and traditional groups on the achievement test, favoring the CHEM Study group. A significant difference existed between grades of the two groups, favoring the CHEM Study group but no significant difference between high school grades earned. Stepwise multiple regression analyses indicated the college grade to be the most reliable predictor of success and high school grade, the least reliable. Highly significant correlations between high school and colldge grades of both groups refuted the claim that no relationship exists between high school and college chemistry. (Author/EB)
