Yes. You should include all students in the cohort that you're choosing to study. You should not provide students’ SAT scores in your file as they'll be matched to your student data from the College Board database. You may want to include ACT scores in your file when available. The system can then use students’ concorded SAT scores (based on the ACT scores) in analyses along with actual SAT scores for the rest of the cohort who have SAT scores on record.
If you are examining SAT total scores in your ACES retention study, then include students’ ACT composite scores. If you’re studying SAT Evidence-Based Reading and Writing (ERW) scores and Math scores, then include students’ ACT Reading, English, and Math scores in your file.
