All sophomores are given the PSAT in the fall. Juniors can pay $18 to take the PSAT if they want to take it for National Merit Scholarship purposes.
The SAT and ACT are equally recognized by colleges and universities for admission. Juniors (3rd year students) and Seniors (4th year students) are given the option to take the SAT or ACT at school for no cost through sign ups in the Fall. Students then test in the spring with their chosen test. If students wish to take either test again outside of school, they can register on their own.
