Thanks polarbear. Public magnet school is not a highly gifted school. Entrance criteria is based on ranking from group naglieri ability test ( no minimum cutoff ), report card, star scores advanced in ELA or math and teacher feedback. From volunteering in DS 3rd grade classroom, there isn't much differentiating going on at all , they just generally go faster and then go deeper into subjects.

In fact on the district's website it states that this school isn't accelerating, and it wouldn't be a good fit if that is what a parent is looking for, which is why we approached the principal originally to assess if this school would be a good fit for DD. He assured me that he would accerelate her and we could make it work.
I'm not sure if they have a lot if experiences with accerelating kids there;I do know that there isn't any child in my son's classroom that is being subject accelerated.
Which is why private is sounding good right now. Except the tuition part of course.
