Does online tutoring work, and does it improve grades? What the research on tutoring actually shows, how large the effect is, when online is as good as in person and when it is not, the seven benefits for children that a classroom cannot give, what makes it fail, and how to tell within a month whether it is working for your child

Parents ask "does online tutoring work" in two tones: hopeful, from a parent who has just found the price, and sceptical, from one who paid for a term of it and saw nothing. Both deserve the same honest answer, which comes from the research on tutoring and not from any tutoring company, ours included. Tutoring works, more reliably than almost anything else in education, when it has four features. Online tutoring works when it has the same four. Most of what fails, online or in person, is missing one of them.

What the research on tutoring shows

Tutoring is one of the most studied interventions in education, and the findings are unusually consistent. Reviews that pool hundreds of studies find that high-quality tutoring adds months of learning in a school year, with the largest gains for students who were behind. Four features recur in the studies with the biggest effects:

1. One tutor with one child, or at most two or three. The effect shrinks as the group grows; a "tutoring" class of eight is a small classroom.
2. A trained tutor. Teachers and trained paraprofessionals produce larger gains than untrained volunteers or peers, though even untrained tutoring helps a little.
3. The school's own curriculum. Tutoring aligned with what the child is doing in class works better than a separate programme that runs alongside.
4. Regular, sustained sessions. Several times a week over months beats once a week for a few weeks, and the effect builds with time.

Why it works is not mysterious. A classroom teacher teaches to the middle of thirty children and sees their final answers. A tutor teaches one child from where that child is and sees every step. Most of what holds a child back is a specific gap, often from years earlier, that nobody has found; a tutor's first job is to find it.

The full table of benefits with the studies behind them, for maths in particular, is in benefits of math tutoring.

What happened when tutoring moved online

The large move online in 2020 produced a wave of studies, and the picture is clear enough to act on. Online tutoring with the four features above produced gains comparable to in-person tutoring in most of them. Where it fell short, the reason was nearly always one of the four features going missing in the move: untrained tutors recruited at speed, attendance that was not enforced, or a video call with no way for the tutor to see the child's working.

So the useful question is not "online or in person" but "does this tutoring have the four features", and for online there are three extra conditions. Which child, subject and age each format suits, with the five questions that decide it, is in online tutoring vs in-person.

When online is as good as in person, and when it is not

As good or better: children from about 8 upward, in maths, the sciences, reading and writing, languages, exam preparation. The shared whiteboard shows the tutor more than sitting beside the child does, and the recording is something in-person tutoring cannot offer at all.

Not as good: children under about 7, who need an adult physically present and a shorter class; children who cannot yet sit at a screen for 30 minutes; anything that needs physical materials (early counting with objects, handwriting formation, lab work). For these, online can still help in short sessions with a parent alongside, but in-person is better where it is available.

The seven benefits for children

1. The class is built on the child's gap, not the class average. The first session is a diagnosis; the plan starts where the child is.
2. The tutor sees every line. On a shared whiteboard, the error is caught at the step where it happens, which is the only place it can be fixed.
3. The recording. A method explained once can be watched again before the test. No in-person tutor offers this.
4. The same tutor every week. The relationship is most of the effect: a child who trusts the tutor is willing to be wrong in front of them, and being wrong is where learning happens.
5. A specialist for any curriculum, from anywhere. A family in a small town, or abroad, can have a teacher who knows their exact exam board.
6. No travel. The slot fits around school, sleep and dinner, which is why attendance, the thing the studies say matters most, is easier to keep.
7. The price. A qualified teacher online from India costs what a university student costs locally, which makes weekly tutoring over months, the pattern the research supports, affordable for families who could not pay local teacher rates for it.

What makes tutoring fail

The four features, missing. In practice, in this order: an unqualified tutor (a student, or a teacher of a different curriculum); a generic programme that does not follow the school; too few sessions (one a week for six weeks is not enough to show); and a child who does not do the work between sessions. There is a fifth, specific to online: a video call where the tutor cannot see the working, which looks like tutoring and is not.

Price is not on the list. Expensive tutoring without the four features fails; cheap tutoring with them works.

A four-week test for parents

Run this from the first session, and look at it in week four.

If all four are there, the tutoring is working and the test grade will follow in a month or two. If none is there, change the tutor, not the idea. How to make the change well is in how to choose an online tutor.

What it should cost

Published rates for qualified teachers in 2026 run from about US$40 to $90 an hour in the United States, £30 to £50 in the UK and A$50 to A$90 in Australia; agencies and centres charge more. Online tutors from India who hold master's degrees and teach these curricula charge about US$10 to $13, with the recording and marked work included. The comparison country by country, and what each price buys, is in is online tutoring worth it.

Where to get help

A free 30-minute 1-on-1 class with a tutor who holds a master's in the subject, on a shared whiteboard, on your child's own curriculum. The first class is a diagnosis: the gap named in writing afterwards, with a plan and the price. The same tutor every week, the recording of every class, monthly billing with no package. For maths, the sciences and English from Grade 1 to the final school exams, in the US, UK, Australia, Canada, the UAE and India. The team page says who the tutors are.
