The SAT and the ACT are both standardized tests often utilized in college admission review and scholarship review. While many things have changed and many colleges and universities have gone to what is called "test optional" for admission, the SAT and ACT might still be utilized for scholarship awarding.
Comal ISD offers all Juniors the opportunity to take one free SAT test in March.
