I explained that he could do 48+ piece puzzles and she pretty quiet for a moment and then said that she would make sure they got some for him for when he starts in the fall.
Sounds like the director is a thoughtful person, which is excellent. But remember that new puzzles alone don't make the difference, the most interesting thing in any environment for most people is 'people.' I would thank the director for the more complicated puzzles, and ask her to allow your son to spend time in the older classrooms. She will probably want to observe him in a variety of setting to determine the best one.
Best Wishes,
