This study appraised the validity of SAT scores, in combination with grades in high school courses and the number and difficulty level of these courses, in predicting college grades in various fields of study, with the objective of providing SAT takers with predictions of their academic performance in different fields for guidance purposes. The possible impact of this feedback on the flow of students into specific major fields was also assessed. Data on an entering class at a large state university provided the basis for the study. The SAT and collateral variables were able to predict college grades in different academic areas by taking into account marked variations in grade distributions among fields of study. These predictions could be potentially useful in academic guidance. Students' predicted grades in the various fields and their intended majors were unrelated. Most students received their highest predicted grades in the humanities, although few intended to major in this area. Hence, such feedback would probably stimulate students to take courses or major in the humanities. Table A-1--Standardized Regression Coefficients for Predicting Actual and Imputed GPAs for Three Fields of Study--is appended.
