Where does the KSHSAA get the authority to think for parents?
When those parents decided to allow their student to attend a KSHSAA member school.
I would think it would be the choise of a parent/ student to decide what opportunitiy to explore no matter what size of school.
They can, they just have do it at a non-KSHSAA member school. Your problem seems to be with your school and it's being a member of KSHSAA, not KSHSAA itself.
