AHL's Development Rule
 

Of the 18 skaters (not counting the two goaltenders) the team can dress for a game, at least 13 must be qualified as "development players". Of those 13, 12 must have played in 260 or fewer professional regular season games (AHL, NHL or any European elite league*), and one must have played in 320 or fewer professional regular season games. All calculations for development status are based on regular-season totals before the start of the current season. Pro games in Europe while player is junior aged won't count.

 
Since 2020-21, players that are not age 25 by July 1st before the season, will be exempted from veteran status.
