USA Hockey's junior program provides opportunities for players ages 16-to-20 to hone and enhance their skills and is an important part of the organization's overall efforts related to player development.
Currently, USA Hockey oversees four junior leagues, including the United States Hockey League (USHL), North American Hockey League (NAHL), Eastern Hockey League (EHL) and North American 3 Hockey League (NA3HL). The USHL is the only Tier I junior hockey league in the United States while the NAHL is the only Tier II junior league in the U.S. Both the EHL and NA3HL are Tier III junior hockey leagues.
To put things in perspective, junior leagues and high schools have had a hand in producing 1,076 players into NCAA Division I hockey roster (67% of all players) for the 2018-19 season.
