These posts are so helpful and have great advices. We are currently in a somewhat similar situation with my DS7. He took the MAP k-2 test in the fall and got 213 on the math test. We are currently not considering grade skipping but is advocating with the school for an accelerated cirruculum for him.
The principal actually suggested to have my DS taking the MAP 2-5 test to better understand his current level in math, before we meet. He doesn't need to take the reading test because the school already had enough information for that. So I am wondering if you request the school to administer the test just for your DS, maybe they can do it without waiting to the next test time?
By the way, I was originally scheduled to meet with the principal, DS' first grade teacher and the LA and math specialists yesterday but the meeting got cancelled and we still have to reschedule. I hope this is not a bad sign. They have been pretty on top of things...
