Our DS5 (Feb. birthdate) skipped K. How we got there:
First, we met with a school admin (pupil services) and we explained that our son is already about to do a certain level of math and he's a chapter book reader... Based on what we see K focusing on, does it make sense for him to go to K (half day) or first grade (all day). She was actually very helpful, told us that she had a bias towards not accelerating but that if we wanted to, the regulations in our area are that the child must have a Age Equivalence of 7 years old in order to have early admissions into first grade. (Determined by a achievement test.)
Then, we decided to have our son privately tested ($$$) to find out what was up. That opened up at least as many questions because the test we took showed that he was gifted but as the psychologist himself wrote in his report "this was not the *right* IQ test for" DS.
We debated up until the very last moment and ultimately formally wrote a request for early admissions which went to the Board of Directors for getting approval (it did). That was the process that we had to learn & navigate. Your process will likely be different!
Okay, so that being said are we happy with our decision? It probably was *not* the best decision for our situation (although some doors have opened up).
First we under estimated the effect of being in school all day long on a child that young. Our DS needs A LOT of sleep. He doesn't fit the mold of "GT who needs little sleep." For the first 6 weeks, after he got off the bus he'd be a total wreck. We eventually figured out a combination of a little nap right after school coupled with going to be at 7PM that helped. The side effect was that he didn't have much free time at all. Come home, snack, 30 minute nap, homework, dinner, bed.
Second we built it up far too much "oh you get to go to first! that's great! You'll learn lots!" Nope. Mid-year and we're still trying to work through a GIEP that is appropriate for him. We probably won't get there completely. But a single skip still is not where he is actively learning and it was a let down to him. When asked what did you learn in math today, a lot of the time we get "I didn't learn anything but the other kids learned...." Sad.
Third, we don't think this teacher "gets" him so it's not a great fit. This one we couldn't have predicted.
Given what we know now, we would have rather go to K and "afterschooled" in the afternoons. It would have given his body a little more time to mature so that sleep was less of an issue. Yes, he'd have all of the K material mastered, but that wouldn't have been so much of a focus for this year (we could still be working through the GIEP process during K). This was an option for us, and since DW stays home with the kids it might have worked. Hindsight and all that.
Then we would have pushed for a 1st grade or 2nd grade skip. (We were told that skipping 1st would have NEVER been an option. But of course now I know a little more
)
That's our mid-year report. Sorry for the length of the reply. I do think it's a case-by-case basis. It hasn't been a disaster for us, but I also wouldn't call it a success either.
