What districts allow 7th and 8th graders to play jv or varsity? Does every district make their own decision about this?
Yes. It's different in every district.
I have been told by parents of certain districts that their own district won't pull 7 th, or 8th or whatever up because its against their policy, mostly to justify that their daughters not getting pulled up. Then to see them pull from these grades a year or two later. Some district constantly pull up, some seemingly never and some only when a truly special player comes along, I support the last scenario.
