In our state once an athlete plays 7th grade ball, they’re only able to play ball for an additional 5 years. My son has a girl in his class that was having trouble with seizures. Parents decided to hold her back to repeat 8th grade due to this & having an April birthday. She travels with her basketball & softball team to all of the games, but isn’t playing, so that she’ll be eligible to play 9-12. One kid from our school didn’t find out the rules & repeated 7th grade. Ended up not being eligible to play his senior year. Definitely find out your states rules before placing your kid in that situation.
