My mother and father were both a year ahead in school. My mother started early, and my father skipped a grade. This was the typical way of dealing with bright kids back then, instead of G&T programs.
It was also typical to hold students back, instead of using resource and other things to keep them at age-grade level, so being held back was less stigmatizing.
By the time I was in school, there were G&T programs, but they weren’t very good. Mainly, they consisted of giving kids additional work over the regular curriculum, and I hated them. I would get put in them after every testing season, then dropped from them after about 8 weeks.
I didn’t know it until I was in my 30s, but my parents tried to have me advanced a grade several times. It’s probably good they didn’t succeed, because given was always my lack of maturity. That, and the availability of G&T programs. My scores on the standardized tests were extremely high, but I just have a knack for those kind of tests. I have taken tests on subjects I have never been taught and scored 85%. I once took a test the entire purpose of which was to measure one’s ability to take multiple choice tests and scores 49/50.
I think I would have done best if I had been left alone in “ordinary” school, even if it had been a little bit below my achievement level, because I just wasn’t interested in being a student in the early grades. As it was, I developed very bad habits with getting moved around a lot, and it didn’t serve me well in high school.
Anyway, what I learned that I would apply to my own son, who thankfully is a “check plus” student, is that if the school used double promotion as the typical way of dealing with exceptional students, so there would be anywhere from 4-6 other double-promoted students on the school, then I would do it. However, if it were a “rare as a hen’s tooth” sort of happening thing, I’d be more reluctant. I wouldn’t want people to think of him as “the kid who skipped a grade,” which, if no one has ever heard of such a thing before, may prove to be almost as stigmatizing as getting held back.
His age relative to the other students is important too. Ask the principal if he will be nearly a year younger than the next youngest kid, or only, say, four months younger, and if he will be close to two years younger than the oldest kid, or maybe only 18 months. Without telling you names, the principal should be able to give you birth dates of the oldest and youngest kids in the class he will join.
You say he is big for his age. That’s a point in his favor. There are actually places on the internet where you can compare his height and weight to that of a kid the average age of one in the class he will join. If he is at least at the 50th percentile for a child, say, nine month older than he is, than that definitely a point in the “DO IT” column. That will help him keep up on the playground and gym class, and not always be at the end of the line if they line up by height. In fact, if he is really big for his age, it might be a good thing. My son is above the 99th percentile for height and weight, and has an October birthday. He is by a head the tallest in his class. I have been asked a couple of times if he was held back. He’s nine, but he looks about 12. People ask us if we’re ready for puberty.
Have you asked his opinion? since you really seem to be at am impasse, and more concerned for his feelings than his academics, why don’t you ask his opinion? Maybe he would very much like to be the kid who skipped a grade. Or maybe he is particularly attached to one friend it would break his heart to leave.
Obviously, you don’t want to leave it entirely up to him, but I don’t see why he couldn’t be included in the discussion. If it turns out he has extremely strong feelings one way or another, that could answer the question.
Finally, have you looked into private schools? maybe he could move up a grade, but go some place where the classes are smaller. Having more individual attention could mitigate much of the concern about his maturity. And if he is really that bright, perhaps he would be offered a scholarship.
