Could Whitley be a 4a school now

Nope, they're not even close, however, just a few years ago Whitley had more kids than south.
Corbin will definitely be 4A come 2019 in the next realignment.
Most likely in a district with Knox, Clay, Rock, and or Perry Central if perry decides to play in the class they're suppose to.
Won't really be a case for geography anymore I wouldn't think.
Since North has been brought up in this thread, it's worth nothing they actually have 6A numbers but some NKY schools play up to 6A for close district games knocking North back down.
If the KHSAA ever forced teams to play in the class there numbers put them in, North would have to travel to Madison Central, GRC, etc. For district games. That seems like a long haul, but that's the same district they were in when there was only 4 classes albeit south and Whitley were both in that district as well.
