I need to ask you guys a really important question. I know a family in a neighboring county that has been pondering on holding their 8TH grade son back. BUT, what my question is. I may be wrong. But, once a kid succesfully completes the 8TH Grade, Is that kid allowed to be held back and still have his eligibility? I thought that I read this somewhere in the KHSAA that once you pass the 8TH Grade you can NOT stay back and be eligible. I am just asking this because I don't want to see these parents make a mistake and their kids be declared ineligible. Any info you guys can give me would be GREATLY appreciated.
