The Study evaluated the predictive validity of various operationalizations of AP® Exam and course information that could be used to make college admission decisions. The incremental validity of different AP variables, above and beyond traditional admission measures such as SAT® and high school grade point average (HSGPA), in predicting first-year grade point average (FYGPA) was also explored. The AP variables examined included the following: the number of AP Exams a student took, the number of AP Exams a student took on which he or she received a score of 3 or higher, the proportion of the number of AP Exams the student took in relation to the number of AP courses offered at his or her high school, his or her average AP score, followed by the number of AP scores the student received that were greater than or equal to 3. With regard to the incremental validity of the different AP predictors above and beyond HSGPA and SAT scores to predict FYGPA, we found that the AP Average score variable produced the greater increment. This report discusses the practical implications of these results in using AP information, in addition to traditional admission measures to improve admission decisions. The following are appended: (1) Descriptive Statistics of Study Variables; (2) Subgroup Differences by AP Measures; (3) Raw and Corrected Correlations between Predictors and FYGPA; (4) Incremental Validity of AP Measures above and beyond SAT and HSGPA to Predict FYGPA; (5) Scatterplots of mean FYGPA by the six AP variables; and (6) Mean FYGPA by AP Average Score for all students with a HSGPA = 4.00 and SAT CR+M+W = 1800.
