There are currently 24 kids in DS's 3rd grade GT class. Last year, there were 29. I think the district will go up to 30 with special approval. It depends a lot on the teacher and the particular group of kids, I think, how well things go with a bigger class. DS had a much better year last year with 29 kids than when he was at his previous school with 23 kids. Of course, the previous school was a regular classroom with a huge range of abilities, whereas the current school is for HG kids, much smaller range to teach.
