As I was perusing thru the latest update on school enrollments, I was shocked to see the dramatic declines at Terre Haute North and South.
Based on the attached files, the following enrollments were reported from the Terre Haute schools in the 2013 classification and then in the 2020 classification :
With enrollments from IDOE-
TH South- 1,463
TH North- 1,432
BHSS- 1,678
BHSN- 1,585
BNL- 1,472
Martinsville- 1,292
Northview- 995
If conferences are made up of similar schools, as @crimsonace1 has stated, these schools are more alike now than ever before in their histories.
