Is he still in this teachers classroom?! I sure hope not.

I would certainly imagine stress was a factor when he took the test. Stress messes with all of us! Makes it hard to read correctly to pick up details properly, to think clearly, etc.

I would start with the school and see if he can't be reassessed by a different teacher. In my children's school district the teacher is allowed to give a recommendation, but does not do any of the testing.
