The PGA's policy board determined that starting in October 2013, PGA tour cards will be awarded based on the results of final three events of the Nationwide Tour, which will include both Nationwide and PGA players.
The qualifying school event will instead become a pathway to the Nationwide Tour.
The fields for the decisive Nationwide Tour events will be comprised of the top 75 players on the junior circuit's money list as well as PGA Tour players ranked 126-200 on the FedEx Cup points list.
Also among the changes announced Tuesday, the PGA said its 2013-14 tour season will start in October 2013 and end in September 2014 with the Tour Championship.
"We are excited to announce these significant changes, as we strongly believe that they will strengthen both tours," PGA Tour Commissioner Tim Finchem said.
