In my dd's case back in the day, our ms team did not have a school funded team. A couple of parents started a "club" team for the middle school kids. Only kids from the MS could try out and initially it was for 7th and 8th graders only. They did not get enough kids from 7th and 8th grade to field a team so they reached out to certain 6th graders to fill out the roster. The team was totally funded out of the parents' pockets. The MS assumed no liability. We were not even allowed to use the school name. We played both school teams and other club teams. This had nothing to do with being a select/travel team. This had all to do with getting the MS kids ready for HS.
