The league is set up by a joint collaboration of RISA, the adult National State Association, and SRI, the Youth National State Association. This allows the players and the field’s insurance coverage, with the league not being part of the individual school systems nor RIIL. All that is necessary, is that each player be a member of some USYS club/association.
At this time the Boys have always played in one division covering 1, 2 and 3 of the RIIL. The Girls have played with 2 divisions, Division 1 and Division 2, with some schools entering two teams, one being a JV or younger team playing in Division 2 with the D2 RIIL teams.
