[4] New regulations adopted in 2021 allow student-athletes in D-I football, men's and women's basketball, men's ice hockey, and baseball to change schools using the portal once without sitting out a year after the transfer, creating uniform transfer rules for all NCAA sports across all divisions.

Student-athletes who wish to take advantage of the one-time transfer rule now must, under normal circumstances, enter the portal within a designated window for their sport.

Student-athletes who are set to graduate with remaining athletic eligibility, and plan to continue competition as postgraduate students, were exempt from transfer windows.

In men's and women's basketball, a single 30-day window opens on the day after the second round of each Division I tournament concludes.

The existing exceptions regarding head coaching changes, a loss of athletic aid, or the discontinuation of a team remain in place.
