Test-required means you must send an SAT or ACT. Test-optional means the college will read scores if you send them. Test-blind (test-free) means scores are not used for admission even if you try to send them. Those three labels are not interchangeable, and scholarship rules can still demand a score when admission does not.
Test-required
You cannot complete the application without an SAT or ACT (a few schools allow a narrow exception). Highly selective private universities and several public systems have moved back into this group. If every school on your list is required, you need a real score plan, not a submit-or-skip debate. Start with which colleges require the SAT or ACT.
Test-optional
You choose. If you send a score, it is part of the file and compared with other submitters. If you withhold it, readers lean on grades, rigor, essays, and recommendations. The practical rule: submit when you sit at or above the college's middle 50% of submitted scores. Full framework: should you submit your ACT at a test-optional college.
Test-blind / test-free
The University of California system is the large example: UC campuses do not consider SAT or ACT scores for admission or scholarships. Sending a report does not help the admissions decision. You may still take the ACT for other colleges on your list, placement, or out-of-system applications—just do not expect UC to use the number.
The trap: optional for admission, required for money
Honors colleges, automatic merit grids, and some majors still want a score when the main admissions page says optional. Check scholarship and honors pages separately. Score-to-aid mapping: ACT scholarships by score.
How to decide in five minutes per school
- Read the current testing sentence on the admissions site.
- If required, plan a test date that lands scores before the deadline.
- If optional, compare your Composite to the published middle 50%.
- If blind, skip sending scores to that campus.
- Check merit/honors rules so you do not leave money on the table.

The bottom line
Required, optional, and blind are different jobs for your score. Label each college correctly, then either schedule the test, submit strategically, or save the report fee.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
