I agree, a half day K is a better choice than full day 1st assuming you can postpone the grade skip by one year.
Where I live it's impossible to get an early entry to PS K. It's quite easy to get an early entry to private K though. It pretty much comes to the fact that the private schools are happy to get extra money
I personally know about 3 kids whose parents opted for early entry private K. I saw work of 2 of those and neither one of them hit me as gt child but admittedly my gt criteria are shifted thanks to DS6. I cannot talk about the 3rd child, I don't know her well enough to judge, but my impression was that getting your child accepted into a private K is not that difficult around here as long as you are willing to pay for it.
