1. Any co-oping application must first have zone approval before being considered for final approval at the provincial level.
2. Schools may CO-OP, if they meet the following criteria:
a. Combined populations of the schools involved (grades 9 – 12) must not exceed 425 students (combined school populations exceeding 300 students will compete in the “AAA” category).
b. Co-oping is limited to "A" and "AA" schools only.
c. A letter from administrators of all schools involved must be forwarded to the MHSAA office.
d. Co-oping can occur for a single sport and single gender in a school.
e. Co-oping must take place for a minimum three year period for that sport (co-ops cannot switch schools during the three years, without MHSAA approval).
f. A maximum of four schools only may combine to form a co-op entry.
g. The team must go under one school name – a new name cannot be created.
h. The schools must maintain administration of the co-op (i.e. it could not be run or controlled by a parent or other group.)
i. The co-op must be beneficial for all schools in the area.
j. The MHSAA will review all co-op applications. They will consider the history of the area, the sport, and how the application will affect the other schools in the area. The committee will also consider historical co-ops.
k. The decision of the MHSAA is final. The MHSAA has the right to monitor co-ops and if it feels a co-op is being abused, has the right to revoke the co-op or place a school on suspension or probation.
l. Co-op is limited to the sports of Soccer, Volleyball, Hockey, Basketball, Fast Pitch, Baseball, Rugby, Ultimate and Football.
m. For the sports of Volleyball, Hockey and Basketball, combined co-op populations will determine the category that the new co-op may compete in at the provincial championship.
3. Exception to the Co-op Rule: All schools that enroll only a single gender, in any classifications (A, AA, AAA, AAAA), may co-op with one other MHSAA member school, in order to compete in the coed sport of Ultimate only. The combined enrollment would determine the classification.
