School district controls ours but this year they were all "the bad news is ya'll got sick too much so the rates are going up and deductible's worse, the good news is it's only going up 10% this year and, oh, probably forever into the future every year, and no we didn't get a second quote, the insurers told us they didn't even make any money on us last year."
There's a shocking amount of incompetence and corruption in school admin. Sometimes it's hard to tell which is which.
