Pretty fascinating reading here.
800 schools. When did consolidation take place? IN did it in the late 50s early 60 and mandated in 1959 that a district must have 1000 students or be forced to consolidate. Seems like there are many rural areas in Ohio that still have less than this K-12.
I'm not sure what the rules concerning consolidation in Ohio were but most of it happened in the 60s. Here, there used to be an eight-school Wyandot County League before consolidation. Four of those schools merged into Upper Sandusky's district. Others combined (with schools in neighboring counties) to form Mohawk, Riverdale and Wynford.
There still remains many very small school districts. There are some school districts around here that graduate 25-40 kids a year. Some of them, like Vanlue, even play football, though others like New Riegel are non-football schools. Interestingly, just a couple years ago there was a consolidation of Bettsville (the Bobcats), which had a graduating class of 12 in its final year, into the Old Fort district. There was discussion of Arcadia and Vanlue merging but that didn't work out.
