The Central Mass. Athletic Conference (CMAC) is the newest High School sports league in the Massachusetts Interscholastic Athletic Association. The conference is the result of the Inter-High League, Southern Worcester County League, Dual Valley Conference, Colonial Athletic League, and Central Mass. Conference combining to create a super conference. The conference includes 34 Public, Vocational, Charter, and Private schools from the Worcester County and Middlesex County.
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. [1] [2]
