All ACES admission validity studies require that you examine a HSGPA value along with SAT scores. Many institutions choose to include students’ HSGPAs in the file they submit to ACES. Sometimes, institutions do not have students’ HSGPAs on file, and this is not a problem. Instead, you can choose to use the “ACES-supplied” HSGPA taken from the student’s SAT Questionnaire data. You will indicate this choice when you begin the ACES study design process online.
If you opt to upload HSGPA, the HSGPA values in your file should not be from very different grading scales (e.g., a mix of 4-point and 100-point grade scales). If your institution rescales HSGPA for admission, then it would be best to submit the rescaled HSGPA. Otherwise, such a mixed scale predictor can adversely impact model performance and results.
