Some of this is old news.
Percentage of teams Tier 1 National Bound teams allowed per district based on population formula has been in place now for 2 years. Mass has not yet hit numbers at , U14 Co-ed, U14 Girls and U15 Co-ed, U18 Co-ed and U16 Co-ed but has hit ceiling at U19 Girls and U16 Girls. Districts do have the ability to waiver teams in to exceed number of allowable teams.
Full-season/Half Season eligibility for Nationals was proposed by Mid Atlantic individual who also propounded a bunch of other changes like all games in certain age groups would have to be played under National Tournament period length rules - this would force 18 minute periods and ice floods at the oldest age group. None of the proposals by the Mid Atlantic individual received recommendations at the Annual Winter meeting in January. Rules will be voted on at the June Annual meeting.
There is a large part of the nation that does not understand that for a lot of Districts youth hockey teams are secondary and school teams are primary. New England District, New York District, Minnesota District & Mass District all run a different model based upon prep/public teams in the winter. Requiring full season received a very chilly reception when presented to the youth council.
Playing Rule changes can't happen this year as last year was a Playing Rule change year.
So what about the Advantage u15 team that won Mass and is heading to Nationals? They are a full season team....
