Yep: listen first. Know that anything you hear in one of these feedbacks is not the end of the world.
If they tell you things you don't understand, ask them for clarification. "Why do you think so? What did you see that made you think so? What exact skill did the test show as missing, and how do we remediate that?" are fine questions.
Having someone else there to write things down is very handy.
As Chay said, a list of accommodations/modifications should be in the report. If it's not specific, ask them to make it so.
Also: ask them for a list of local resources. If something's going on, you should be leaving their office with pointers toward next steps.
