The state superintendent is largely an administrative post, with little actual power over setting policy, but able to use the position to advocate for their priorities across the state.
The superintendent is responsible for governing Wisconsin’s public schools, administering state and federal aid, and offering guidance to teachers and administrators. The superintendent also crafts a spending request every two years to run the agency and provide state aid to public schools, which is subject to approval by the Legislature. [Emphasis mine]
So they have little power, except what’s enumerated in the second paragraph in the quoted part?
So why would anyone want to run?
