| Abstract: | The efficiency of aptitude and mental ability measures to predict high school grade-point average for Negro students in secondary school was studied. The total sample of 222 students was randomly divided into two samples in order to determine the consistency with which the variables predicted the criteria. The predictor variables were: The Differential Aptitude Tests, the California Test of Mental Maturity, The Cooperative Ability Tests, The Sequential Tests of Educational Progress, Junior High School Grade-Point Average, and Social Status Ratings. The data were analyzed by multiple linear regression. The instruments consistently yielded substantial correlations with High School Grade-Point Average. Negro students appeared to be as predictable as other groups. |
