What do I need to do to qualify to play for NCAA division 3 team?

I’ve looked through a bunch of sources and I still have no idea what I am supposed to do! I swim but do not necessarily need to swim in college. I want to use swimming as a possible means for scholarship money. Do I have to sign up for NCAA eligibility when the site says it’s only for those who want to compete for d1 or 2 teams. Basically, what do I have to do to be eligible to participate?

D3 schools don’t award athletic scholarships. Your sport can, however, help leverage your admission nto a D3 school with good FA.

No, you don’t have do the NCAA clearinghouse for D3. If you want scholarship money, though, that’s D2 and D1, and you do need to do the clearinghouse, send in your scores and transcripts
