The Pac-12 passed sweeping changes for athletes in all of the conference's sports Monday, guaranteeing four-year scholarships, improving health care benefits and liberalizing transfer rules.

The changes announced by the Pac-12 presidents and chancellors include many of the same proposals outlined in a letter to university leaders in the five major football conferences in May. The conference also said its presidents and chancellors reaffirmed their support for stipends to cover the full cost of attendance.

Pac-12 Commissioner Larry Scott has said that figure will likely range between $2,000 and $5,000 per athlete depending on the university. The 65 institutions in the five major football conferences — granted autonomy by the NCAA earlier this year — and 15 representative athletes will vote on the issue at the group's inaugural meeting in January.
