Submitting subject test scores?

If a school asks that I submit all SAT/ACT scores, does this also apply to subject tests? Also, I took the SAT test proper but I don’t want to send those scores (they’re nowhere near as good as my ACT scores). If I send my subject test scores, am I required to send EVERYTHING?

For clarification, I am not applying anywhere that requires subject test scores, I’m just sending them to help my application.
