Many students apply to colleges which require test scores as part of their admissions process.
Colleges use the scores as one measure of a student's academic Skill. A student's high school record is considered the most accurate single predictor of readiness to do college work. However, as high school courses and grading practices vary widely, colleges need a standard measure of the abilities that are important for making decisions about admission. Therefore, certain tests are administered. The combination of these test scores and high school grades are considered the best predictor of academic success in the first year of college.
