A 207 RIT is above the 99% for beginning of 2nd grade and at 91% for beginning of 3rd grade. At the meeting, I would ask to have a copy of his MAP test report and ask the teacher how you can work together to help him achieve his MAP growth goals. For example his math growth goal should be ~10 points (see page 78). That makes it a specific, measurable goal and more likely to get attention.
Good luck!
