Mostly because they would likely share a district with Webb City I was curious and did some checking myself. This is of course assuming the data on the DESE site is correct and I'm not missing students being in lumped in as part of a co-op with some other small schools it looks like if if lets say the number of schools dropping out is 5 then Monett could be the smallest Class 4. Any more than that and they certainly look to stay Class 3. This is of course with a pretty low degree of confidence. I don't have numbers on Lutheran South who was 710 last cycle but for this excercise I am going to have them staying at 710 and being the largest C3. This is what I come up with:
^ East (KC) 767
^ Potosi 730
^ Monett 721
----------------------
V Lutheran South 710
V Sullivan 703
V KC Center 700
V Miller Career Acad 685
V Logan-Rogersville 681
V Pleasant Hill 677
V Jennings 673
V Mexico 664
Since right now the number looks like it could be closer to 6-8 spots. I think odds are probably are far greater that Monett stays Class 3
I could have missed something but with the current state of how programs are dropping out it is going to take quite a bit for a school to move up a class right now.
