Concrete vs soft signals
Concrete signals: these are the ones that matter
Three signals tell you the tutoring is landing:
The student can do questions they couldn't do before: quadratic equations, organic mechanism diagrams, structured essay paragraphs. Watchable and repeatable.
Past-paper marks on tutored topics are climbing. Track them. If a student went from 4/10 to 7-8/10 on quadratics questions, the tutoring is working on that topic.
The student can explain the topic back without prompting. Ask "how would you approach this?" and listen for the method. That is the strongest retention signal, because real understanding survives the gap between sessions.
Soft signals: encouraging but not enough on their own
The student talks about the subject at home, unprompted.
They engage more in class.
They say they feel more confident.
The tutor reports good progress.
Take these as supporting evidence, not proof. Confidence without competence is a common trap. A student who feels confident because the tutor explains things clearly can still flounder on independent past-paper work.
The check-in conversation
At session 4-6, have an explicit check-in with the tutor. Ask directly:
What can [child] now do that they couldn't six weeks ago?
What are they still struggling with?
What's the plan for the next 4-6 weeks?
How are they doing on independent work between sessions?
A strong tutor answers each one specifically. A weak tutor deflects with generic positives. How clear the answers are is itself a quality signal.
Common reasons tutoring doesn't translate to grade lift
Understanding in a session is not retention
A student who follows the tutor's explanation in real time but can't reproduce the work alone hasn't learned it yet. The tutor should be drilling independent practice during sessions and setting work between them. If sessions are mostly explanation with little student-driven practice, that's a structural weakness.
Wrong topic focus
Sometimes the tutor covers content the student already understands and misses the actual weakness. It shows up as a tutor reporting good progress while past-paper marks stay flat. The fix is a deliberate diagnostic: sit down over recent marked papers together and find what specifically loses marks.
No homework or between-session practice
Tutoring is at most one to two hours a week. School delivers 25-30. If the student isn't practising between sessions, the tutoring time alone can't drive meaningful gain. Strong tutors set explicit work between sessions and review it at the start of the next.
Lack of student buy-in
A student attending tutoring against their will rarely sees grade lift. The tutor can teach competently, but the student won't engage with the practice or take on the techniques. If your child is consistently disengaged, the conversation to have is with them, about what they actually want, rather than with the tutor.
When to switch tutors
Switch if any of these holds after six sessions:
No concrete progress signals on tutored topics.
The tutor's check-in answers are vague rather than specific.
Your child doesn't want the sessions and rapport hasn't built.
You can't say what the tutor is working on or planning.
Your gut says it isn't the right fit, backed by the points above.
Switching is awkward but rarely regretted. The replacement tutor often delivers progress within 4-6 sessions, because they start from a clearer diagnostic and skip the patterns that weren't working.
When to stick with it
Stick with it if:
there's at least one concrete progress signal, even if grades haven't moved yet
the tutor sets out the plan clearly and can show progress on it
your child engages with sessions and does the between-session work
the setup feels right even if results haven't fully shown up yet
Sustained tutoring compounds. Sessions 7-12 often show more lift than sessions 1-6, because the foundations are built and the work moves into harder application. Don't switch out of impatience when the underlying signals are good.
Tracking grade lift over time
A simple habit helps. At session 1, ask the tutor to run a baseline diagnostic: a score on a past paper or a topic-area assessment. Repeat the same or a similar diagnostic at session 6 and session 12, and track the scores. The trend should be up.
If the scores aren't rising over weeks of tutoring, something concrete needs to change. A diagnostic-led approach heads off the failure mode where everyone says it's going well but no one can point to a specific gain.
