Due to the over representation of the privates/non-boundaried on the IHSA Board of Directors
(5 of 10) I don't see your plan ever being implemented.
From the IHSA website: "The IHSA Board of Directors consists of 10 principals elected to three-year terms, plus a non-voting Treasurer who is appointed by the Board."
The current Treasurer just so happens to be from a private school (Decatur Christian). He doesn't vote, but you included him in your count of current directors from private and non-boundaried schools. That leaves four of ten.
Also from the IHSA website: "Seven members are elected from geographic divisions, while three members are elected at-large, one from an ethnic minority, one from the underrepresented gender, and one from a private school."
As it currently shakes out, all three of the at-large directors are from non-boundaried public or private schools, but only one of them is there because he represents a private school. I think you may not realize this, but the composition of the board changes every year. New members come on while members completing their terms rotate off. Conceivably, a future board could consist of 10 voting members, just one of whom is from a private school. Indeed, many past IHSA boards have been constituted exactly that way.
