@lilyesh Repeating seems pretty common these days ( esp with boys and esp for athletic reasons). It’s really common in some communities. I have a nephew who was “redshirted/repeated” for athletic reasons. I worked out for him. He now plays his sport in college and he needed the extra year to be tall enough to compete.
It used to be, that kids (boys esp) who were weak academically coming out of high school would take an extra year as a PG. That’s less common now. Today, the repeats seem to happen in 9th/10th grade. It’s all good. Just depends on what the goals of the student and parent are and what makes the most sense.
Some parents really push for it and I have seen it make a difference in the kids social interactions ( esp at very young ages). But personally, I wouldn’t do it for my kids.
If you’re not interested in repeating than I would not bring it up. I’m not sure why it was brought up upthread ( sorry I didn’t read the whole thread). If it’s age based only ( quick read) there doesn’t seem to be a need. Again, it’s your choice. I’ve seen kids who are really young for their age do very well and kids who were old in the grade not do so well. It depends on the kid.
