Thanks for the responses! Unfortunately part-time homeschooling is not an option in our state. My son will get a chance to tour the school and go into the gifted class on a different day than the parent open house but the principal is not keen on letting us parents sit in on the class so I doubt she will want to let my son do that. I think I will push for at least me sitting in--otherwise I feel that I can't make a well-informed decision. In the Montessori it is the complete opposite--they require a student to spend several hours in the class before enrolling.
Thanks for the making a spreadsheet suggestion and the link for the Davidson Database.
Yes, we are fortunate that we do have homeschooling as a good option.
