My take that seems to never get cold: let kids skip grades. Anything I hear against this runs into the wall of the lived experience of several people I know including mine. It’s fine! And it doesn’t have to be permanent: if a kid doesn’t thrive in the next grade, put them back! Then everyone at grade level gets grade level resources and teachers get students at the right level of knowledge. Having to homeschool or pay for private school to get this simple experience is wild to me.
