A great math tutor does three things well: they can identify exactly where a student’s understanding breaks down (not just where the grade is low), they explain the same concept multiple ways until it clicks, and they give targeted practice rather than assigning the same exercises the school already assigned. Subject knowledge alone is not enough — effective tutoring is a teaching skill, not just a knowledge transfer.
Finding a math tutor is easy. Finding one who actually moves a student’s grade is harder. There are a lot of tutors who are good at math but not particularly good at teaching it to someone who is confused. Knowing what to look for before you hire saves months of underwhelming progress.
Red Flags to Watch For
They only do the homework with the student. Sitting beside a student and helping them complete assignments produces homework marks, not test marks. If the tutor’s session is indistinguishable from the student just doing their homework with a helper present, it is not tutoring — it is a more expensive homework completion service.
They cannot explain why a method works, only how to apply it. A tutor who says “just memorize this formula” when a student asks why it works has reached the limit of their teaching ability. Students who understand the underlying reasoning perform better on unfamiliar problems than students who only have procedures.
There is no assessment at the start. A tutor who starts working through the current chapter without first identifying where the student’s gaps are is working blind. Good tutors spend at least the first session understanding the specific concepts the student does not have.
What Good Tutors Actually Do
Good tutors ask the student to explain their thinking out loud. This reveals the exact point where understanding breaks down — which is almost never where the student thinks the problem is. A student who says “I don’t get derivatives” might actually have a gap in function notation that makes the derivative definition confusing.
Good tutors vary their explanations. If one explanation does not land, they try a different approach — a different visual, a simpler example, a connection to something the student already knows. Repeating the same explanation louder is not effective teaching.
Good tutors assign targeted practice between sessions. Not a textbook chapter, but 8 to 10 specific problems that address the exact skill they worked on in the session. This follow-through is where most of the actual learning happens.
Questions to Ask Before Hiring
- “What do you do in the first session with a new student?” (Looking for: assessment, gap identification)
- “How do you handle it when a student just does not get an explanation?” (Looking for: multiple approaches, patience)
- “How do you track whether a student is improving between sessions?” (Looking for: concrete measures, not vague reassurance)
- “Have you worked with students in this specific course before?” (Course-specific experience matters — AP Calculus BC and Grade 11 Functions require different knowledge)
- “What do you expect from the student between sessions?” (Looking for: an expectation of independent practice, not passive attendance)
How to Measure Whether It Is Working
After 4 to 6 weeks of tutoring, test scores should show some movement. If they do not, either the tutor is not addressing the right gaps, the student is not doing the practice assigned between sessions, or the session frequency is too low.
A useful signal: ask your child to explain a concept to you after a tutoring session, without their notes. If they can explain it clearly, something was learned. If they cannot, the session may have produced surface-level recognition without real understanding.
Group vs Individual Tutoring
Group tutoring (2 to 6 students) works well for students who are keeping up with the course but want structured practice and accountability. It is more affordable and has the added benefit of seeing how other students approach problems.
Individual tutoring works best when the student has specific gaps that differ from their peers, needs to rebuild confidence after a difficult period, or is working on a narrow goal like a specific exam (AP, IB, AMC) where the preparation can be precisely targeted.
Some families use both: group sessions for regular coursework and individual sessions closer to exams. This combination often delivers better results than individual tutoring alone at lower cost.
Exploring Scholar offers both individual and small-group tutoring for high school math in Toronto. Our instructors are trained to identify gaps, not just work through homework. See our programs page for details.
Frequently Asked Questions
How often should a student see a tutor?
For a student who is behind, two sessions per week of 60 to 90 minutes each is the most effective frequency. Once the gap is closed and the goal shifts to maintenance, one session per week is usually sufficient. Less than one session per week rarely produces consistent grade improvement for a student who is struggling.
Is a university student tutor as effective as a professional tutor?
It depends. A university student who recently took the course and is genuinely good at explaining material can be very effective for Grade 11 or 12 coursework, especially for a student who just needs someone to work through problems with them. For more advanced preparation — AP exams, competitive math, IB — experience with the specific curriculum and exam format matters a lot more.
How long does it take to see grade improvement with tutoring?
For most students, the first meaningful test score improvement comes 4 to 8 weeks after starting tutoring. Earlier improvements can be seen in homework completion and confidence, but test scores require enough time for the new understanding to consolidate under exam conditions.
Should the tutor work through the student’s school homework?
Using homework as a diagnostic tool — to see where the student gets stuck — is fine. But completing the homework for the student, or walking them through it problem by problem, does not build independent ability. Good tutors use homework to identify what to teach, then practice similar problems separately.
