Many students and parents often ask us questions about how easy one school is versus another or where their best chance is. Most college counselors and tutors answer these questions with experience and intuition, but we believe data can add a third layer to the equation. Using the Office of Institutional Research, Common Data Set, and other supplemental data from universities, we can dig deep into the statistical data behind each university. This data can give us insights into the ways schools are thinking about admissions, average SAT/ACT scores, and other activities. In this article, we will cover ways to uncover GPA and SAT sensitivity, school selectivity, and changes in selectivity over time.
