The College Board offers both a reasoning test and several subject tests Which should you take as part of the college application process?

The decision of whether to take the SAT Reasoning Test (now just called the SAT) or SAT Subject Tests (discontinued in 2021) depends entirely on the fact that SAT Subject Tests are no longer offered.

Therefore, the only option now is the SAT. Many colleges still require or recommend the SAT, but some are test-optional or test-blind. You should check the admissions requirements of each college you're applying to individually to determine whether the SAT is needed.
