I'd start my own thread but I wanted to quote this and just quickly hijack. Sorry!
Dd10 has both in 4th and 5th grade fallen into the "C" range on that chart. While I've always thought that math is an area where I see some ability in her, I've never thought she needs as much acceleration as that chart would indicate. She just passed the district tests for subject acceleration in math in 6th grade, but barely. She was right at the # needed on the MAPS and just slightly higher than the requisite # on the 7th grade math pre-test (they needed to get a 70% or higher on that and she was a few percents higher but not like 90%). Would you really accelerate more than one grade in math for a kid like that? I'm not even positive if her middle school is going to put her into the accelerated 7th grade math given that she just made it. She could wind up in non-accelerated 7th grade math which I am likely fine with.
