November signees for Spring sports generally enroll for the following Fall semester although some graduate early and enroll for that Spring's classes but they generally do not compete straightaway but wait until Fall. Always a few exceptions, of course.
I have pasted the press release from the most recent signing class below. Dated Nov 13, 2024. They will probably enroll for classes next Fall, eligible for Fall's schedule, although they might show up on campus during the summer to get a leg up. Note that every freshman and transfer on the softball team showed up last July, ready to get to work. I will also add it to the link to the post where I added the link to top signees around the country (I should have done it then!).
