Thank you all for the input!

This what I did so far. I called the admissions director and casually asked him about the meeting. Seems it might not be a one on one with the teacher but rather a couple of families at a time. I am bringing some copies for her of DS's work and report just in case, but assuming I will not have the opportunity to give it to her.

I told the admissions director about my son's results and he said I should give them to the teacher. He said he was going to alert her to DS being PG and let her know I will be bringing her the results from the testing. This was she is already prepared for it without me taking her off guard.

I think I will wait a few weeks and let her get to know him. Then I will ask for a meeting with her to see what she would suggest.

Thank you for brainstorming with me...I need it.
