Thanks aeh for your inputs.

We've been contemplating this a lot. I don't know why the teacher urges us doing the tests. He is doing just fine academically with all As and one C in English. he has made friends and very happy. He is not disruptive at class just not as engaged. The teacher's concern was he might not catch up at higher grades, but from what we've seen , he is actually doing better every year. Back in lower elementary grades, he is a solid B student.

I am concerned about identification of learning disabilities and the label attached on him. Since we won't consider medication, why can't we just wait it out.
