TheCentral Mass. Athletic Conference (CMAC) is the newest High School sports league in theMassachusetts Interscholastic Athletic Association . The conference is the result of theInter-High League ,Southern Worcester County League , Dual Valley Conference,Colonial Athletic League , andCentral Mass. Conference combining to create a super conference. The conference includes 34 Public, Vocational, Charter, and Private schools from theWorcester County andMiddlesex County . The newly created conference is a member of the 2nd district of the Massachusetts Interscholastic Athletic Association's nine districts, being the only athletic league assigned to the district.[ 1]
The conference was created for schools to do better under the new MIAA state tournament format; allowing them to more easily schedule stronger opponents. This is done by creating alignments based on power ratings from recent seasons at the beginning of each year.[ 2] [ 3]
