I'm new to all this, but if sounds as it there is a wide discrepancy between the first tests your son did, and this new set of achievement testings. Was he feeling ok the day of the test? Was he just not " into " it so to speak...there could be so many variables. I hope someone on here can guide you to more interpretation, there are many on here that are a wealth of knowledge on all these testings etc. I hope the team meeting is positive and the plans continue on as you had planned for.
