Alright calculating the classes has several steps based upon MSHSAA manual there is a dozen steps in which to prevent schools from playing schools more than twice their size or in their case what they specify 2.0. Here is the official documentation.
Classification: District and State Tournament procedures are covered in By-Law 5.1, including the collection of enrollment data and the general procedures for classification. This information serves to further describe the procedures for classification breaks and district assignment release.
Annual Schedule for Schools Reclassification: MSHSAA member schools are classified annually based on updated school enrollment figures. The schools in each classification, or class, will compete against one another in MSHSAA-sponsored district and/ or state competition. The District and State Music Festivals are evaluative only. MSHSAA does not sponsor state championships in “emerging sports/activities” (see By-Law 5.2) and there are no classifications.
Determination of Classification Breaks Between Classes: The activities sponsored by MSHSAA are broken into classes based on school enrollment. Once classes are established based on the classification procedures, the classification breaks are defined. Classification breaks are the numerical enrollment lines which describe the enrollment span of a particular class, and are based on the largest school’s enrollment in that class.
Classification Procedures:
1. Official Enrollments Finalized and Registrations Reviewed: Enrollments declared and finalized; enrollments are combined 2023-24 MSHSAA OFFICIAL HANDBOOK Page 125 BOARD POLICIES for the schools in Cooperative Sponsorships (sport/activity specific). For the sports of cross country and track & field, determine which gender has more registrations, and begin Step 2 with that gender. (See By-Law 5.1)
2. Break into Last Year’s Classes: In enrollment order, place the current year’s registered schools a) into the same number of classes as the prior year, and b) into the same numbers per class as the prior year.
3. 2.0 Differential Review: Calculate the enrollment differential for each class by dividing the largest school’s enrollment by the smallest school’s enrollment. Determine if the differential for each class, other than Class 1, is 2.0 or below (differentials from 2.01 to 2.04 will be rounded down to 2.0). If all classes above Class 1 have a differential of 2.0 or less, the number of classes are final (end of procedure, see Step 7). If any class’s differential (other than Class 1) is greater than 2.0, the number of schools in the upper classes should be adjusted to see if, by moving schools down from a larger class into a smaller class, all differentials can be made to meet the 2.0 limit. Moving up from Class 1, the class counts should either be equal to the number in Class 1 or the count should decrease as the class number increases (preserving an equal or waterfall approach) AND all differentials, other than Class 1, should be at 2.0 or below. If this is successful, the procedure ends; see Step 7.
4. Efforts to Stay Consistent: Attempts will be made to adjust the class lines and the numbers in the classes while maintaining the 2.0 differential BEFORE adding a class. (See Classification Note 8.) If this is not possible, move to Step 5.
5. Add a Class: Increase the number of classes by one and place up to the applicable percentage of the total schools in the sport/activity into Class 1. (See also Notes 1 and 2). Number of Classes after adding a class Now 2 classes Now 3 classes Now 4 classes Now 5 classes Now 6 classes Max percentage of total to place in Class 1 70% 50% 30% 25% 20%
6. Percentage in Class 1 and Equally Divide the Rest: Equally distribute the remaining percentage of schools into the rest of the classes above Class 1. Return to Step 3 and review the differentials. Repeat as needed until the number of classes is finalized.
7. Ties: Enrollment ties across a class break will be ignored until after the Championship Factor has reclassified schools, due to those changes solving most ties.
8. Championship Factor Review and Adjustments: Move to Championship Factor section below for this second step of the classification process.
Classification Notes:
1. The maximum number of schools in a class for football is 64.
2. The maximum number of schools in a class for team sports is 128, and the minimum number of schools in a class for team sports is 32.
3. 8-Man football: The total enrollment of participating schools or co-ops must be 150 or less (grades 9,10,11).
