If you're applying for admission in 2020, your official ACT or SAT scores can be sent directly from the ACT or SAT websites. Official documents usually take 1-2 weeks to appear in your file after they've been requested.
Scores also are accepted as official if they are printed on your high school transcript.
If you're applying for admission in fall 2021 or later, you don't need to submit your ACT or SAT score. Read more about test-blind admission requirements for fall 2021.
