DS5's school decided to have him unofficially take the end of third grade state math assessment and have it graded by someone who doesn't know him and graded like any 3rd grader. They reported to me that he only got one wrong and it was due to a vocabulary term in math he wasn't familiar with. Good news too as this helped them to see that he would definitely be able to start in 4th grade math next year (even though it still will be pretty easy for him). At least now they know they don't have any doubts that he can do it. And DS really enjoyed filling in the bubbles on the scantron. ; )
