Use a Mentor Between Formal Pool Coaching Sessions

A practice mentor can help count attempts, replace marked balls and record an agreed observation between lessons. The role becomes harmful when it quietly turns into a second, conflicting coaching system. Use this charter to define ownership, language, consent and stop points. It is distinct from choosing a qualified coach because it governs what happens after formal instruction.

Use a three-owner mentor charter

A mentor can also provide company, scheduling support and encouragement. Those are valuable without requiring technical authority. Credentials, safeguarding needs and venue policies still matter when selecting anyone who works with a minor or vulnerable player.

Ownership and boundaries
OwnerMay doMust not do
Coach/instructorAssign diagnosis, change and testAssume unseen practice followed the plan
PlayerConsent, stop, ask and keep the logPractice through pain or unwanted recording
MentorCount, reset, record agreed fields and neutral videoAdd mechanics, diagnose health or overrule coach

Use neutral language during the block

If the assignment is unclear, pause and write the question for the coach. Guessing is not continuity. Delete or retain recordings according to the player's consent and applicable venue policy; no upload is required.

Worked example: protect one finish-line assignment

A formal instructor assigns twelve straight stop shots with the cue finishing through a visible shaft-width gate. The mentor replaces the balls, marks pocket/stop/gate and gives no feedback until the block ends. Results are 9 pockets, 7 stop-window finishes and 8 gate matches. On three misses the gate still matches, so the mentor does not announce that the stroke caused every miss.

The mentor returns the sheet and two consented representative clips. The player's next question is: ‘The gate held on eight shots but the stop window held on seven; should the next block keep the gate and test contact height?’ The coach owns that decision.
