I find some of the post here about summer birthday kids and the kindergarten decision very interesting.
So we waited, rather than enter kindergarten at barely 5 years old he entered at barely 6. No regrets....and so he is 2025, and not 2024.
I think that's fairly common story although there's a lot of rationalizing that goes on. I n my state they even moved the date back from December or January 1 to Sept 1 several years ago so your kid would have right on the cusp in our state Holding your kid back to re-do 8th grade, while his lifelong friends move on, for a slightly better chance at being a high 2024 over an above average 2025 or maybe not getting cut from sports altogether is different and much more common story. I can look at my kids yearbook and see at least 10 out of 200 boys that did that and I don't think it will matter one bit. And I've heard some of the other boys and parents call them red-shirts.
