The Interscholastic League originally voted and awarded the State Champion or had playoffs if teams were tied in the standings.  Teams were comprised of 7 players (Left Wing, Center, Rover, Right Wing, Cover Point, Point and Goal) until the 1925-26 season.  Schools played outdoors (including Blackstone Pond, East Side Skating Rink, Mashapaug Pond, No Bottom Pond, Roger Williams Park, Scott's Pond, Slater Park, Hammond Pond, Railroad Pond and York Pond).
