The ACT and SAT are the two admission tests used by most colleges and universities in the United States. Most post secondary institutions require prospective students to take one of these exams. The majority of colleges will accept the results from either of these tests, but it is always a good idea to check with specific colleges or universities about test preferences or requirements.
The PSAT is traditionally taken by Juniors in the month of October. Students who are college bound and would like to take the PSAT for extra practice before Junior year can take it as freshmen or sophomores.
The ACT and SAT are traditionally taken by Juniors. Big Sky High School administers the ACT for free to all Juniors in the month of April. However, both the SAT and ACT are offered year round outside of the school. Some students may retake the test a number of times if unhappy with their scores. Most Colleges require SAT or ACT scores when you apply during Senior Year of high school.
Ambitious students may choose to take the ACT and SAT prior to Junior year in order to practice.
