Group by standard
Age bands discourage half the court.
A scholarship, usually. It is the one thing nobody can honestly promise.
College tennis places are scarce and full scholarships scarcer still, yet the promise of them funds a great deal of junior coaching. The honest version is an assessment of where a player actually stands and what would have to change — less compelling, and the only thing worth paying for.
Grouping is the practical decision that matters most week to week. Age-banded squads are easy to schedule and routinely put a four-year player beside a beginner, which bores one and discourages the other. Standard-based grouping takes more effort and is the difference between a player continuing and quietly stopping.
And in Florida, heat is not a footnote. Heat illness in junior sport is predictable and preventable with mandatory breaks, hydration and a willingness to suspend a session. A coach who runs a squad through the hottest part of an August afternoon because it was booked is making a decision about somebody else's child.
