A court decision today could prevent some private schools from moving up in the state classifications. Five private school students are suing the Missouri State High School Activities Association to repeal the private school multiplier. MSHSAA believes private schools have an unfair advantage in athletics and decided last spring to move smaller schools into higher classifications. The students argue that by being in a higher class, their chances of making end of season state tournaments, which in turn, they argue, limits their chances of athletic scholarships. The decision, which is expected this morning could affect winter and spring sports if it falls in the students favor.
