There are so many considerations! And the reality is you can only do it one way for one kid, so how do you ever really know if what you did was best? You only know how that turned out! Some thoughts, many conflicting, from various approaches.
If you live in a place where people regularly hold back their kids, the older starting age becomes the norm and a very typical 5 year old is disadvantaged because classmates are all typical 6 year Olds and that much older, more mature, etc. In this kind of community, there are often well developed programs for that extra year of preK, so kindergarten expectations are a bit higher. Choosing not to redshirt was almost the same as choosing to accelerate in this community.
A friend whose D was on the younger side noted that in middle school, the D’s friends were mostly interested in hanging out and meeting up with boys. The D, being younger, had no interest in that at that point. Her mom felt that her relative immaturity got her another year or so of less distraction in school and more interest in academics. The D really got a bit more invested in school at that point and became a more committed student. Her mom felt that her relative immaturity was a gift.
Our LPS likes kids to start early so that if there’s any kind of issue, they can repeat K, often with additional support, and not have a huge age differential going forward - just the one that redshirting would have given them.
A friend whose D ended up starting at the normal age in a community where everyone held kids back felt her D didn’t have much gas left in the tank for ECs at the end of the day. Another who started at the normal age was persuaded to repeat because the D regularly fell asleep. Both felt that their kids were physically not quite up for it although in other ways they were. Both were absolutely fine later in their schooling.
If you are supposed to be doing everything possible to take advantage of your child’s natural ability to learn at this age, what do your extra year options look like if you take away that stimulatingyear of kindergarten? We had a single Focus on Five program available but few other good options beyond kindergarten. We chose the latter for a boy with a summer birthday. It worked out fine. But I suspect that if we’d held him back, we’d be saying the same.
It’s hard to imagine now, but if you want to add a year anywhere along the way, (repeat 9th and apply to BS, PG year for sports, gap year), consider how that would align age with peers. A friend’s S who redshirt for K and did a PG year for recruiting succeeded in the latter but really felt out of whack his freshman year. He was the age and maturity of most juniors but “stuck” with the freshmen. Like everything, he found his way, but it was hard. Then again, maybe he wouldn’t have been recruited any other way…
