The function of standardized tests is to give colleges a way to evaluate all their applicants on an equal level. Comparison of grades received in courses or on exams is not always enough because different schools have different academic standards. An admissions counselor at a university has no way of determining how challenging the calculus or economics course you took was. By comparing your score on a standardized test to the score of another student who took the same standardized test, the counselor has a better idea of how the two of you compare.
Most standardized tests are designed to measure a student’s skills, rather than a student’s amount of knowledge. The questions in these tests evaluate your ability to solve problems, not your knowledge of facts (such as important historical dates, or parts of the human anatomy).
Most of the US colleges and universities require that all their applicants take one or more standardized tests. These tests include the SAT (Scholastic Aptitude Test), GRE (Graduate Record Examination)
