December SAT scores and applying to colleges

My daughter is taking the October and Dec SATs. Son only took the October. She hasn’t signed up for the Dec test yet. Can she start applying to colleges before she signs up for the Dec test? Will the Dec test superscore still show up in time for the college admissions decisions?

For regular spring decision colleges and unis that would be part of the file most likely. Even October is cutting it close for some EA colleges/unis. But of course she can apply anytime, the colleges and unis just don’t start reviewing until the application fie is complete so after they receive October scores the review could start. Why so late on the tests?

each school will usually state the last test date they will look at. December seems late.

Thank you. I will be checking with each school. She is not applying early admission for any schools.

December is fine. Many schools will even accept Jan and Feb test sittings for Regular admissions evaluations
