The Benefits of Tutoring: What Research Shows Actually Works

Tutoring is not new, but the evidence for it has grown a lot in the past decade. Researchers have run many randomized trials, the gold standard for testing whether something works, and the results are consistent: well-designed tutoring helps children learn.

How much does tutoring improve learning?

A review of randomized studies by J-PAL found tutoring raised achievement by about 0.37 standard deviations on average. In plain terms, that would move a typical student from the 50th to about the 66th percentile. In education research, that is a large effect; many school programs struggle to reach a third of it.

Why does tutoring work so well?

In a class of 25, a teacher has to pitch each lesson at the middle. A child who missed an earlier step keeps building on a shaky foundation, and may be too embarrassed to say so. A tutor can do three things a classroom cannot:

• Find the exact gap, often a skill from a year or two earlier.
• Adjust instantly, explaining a different way the moment an explanation does not land.
• Give immediate feedback, so mistakes are corrected before they become habits.

Children also tend to ask more questions one-to-one, because no classmates are watching. That combination of precise targeting and constant feedback is hard to replicate any other way.

Does tutoring help older students too?

Yes. A common belief is that it is too late to help teenagers who are far behind. Two randomized trials of Saga Education math tutoring for ninth and tenth graders in Chicago challenged that. Students tutored in pairs during the school day gained 0.16 and 0.37 standard deviations in math in the two studies, and their grades improved in math and in other subjects too. The study was titled, fittingly, "Not too late."

What makes tutoring effective?

Stanford's National Student Support Accelerator describes high-impact tutoring as having these features:

• Frequency: at least three sessions a week, each 30 minutes or more; 45 to 60 minutes for older students.
• Group size: one-to-one or a small group.
• Relationships: a deliberate focus on the tutor-student relationship.
• Data: regular checks of what the student has learned.
• Curriculum: alignment with what the school is teaching.
• A trained tutor with ongoing support.

J-PAL's review adds that trained tutors, such as teachers and paraprofessionals, were generally more effective than volunteers or parents, and that effects were strongest in the early grades.

What are the benefits beyond test scores?

• Confidence. Children who stop feeling lost often start participating in class again.
• Better grades across subjects, as the Saga studies found.
• Study habits, such as showing work and checking answers.
• A trusted adult outside the family who notices how your child is doing and celebrates progress.
• Calmer homework time at home, which many parents value as much as grades.

Does online tutoring have the same benefits?

Research suggests it can. A 2025 randomized study used the same tutors to teach some children online and some in person, and found no significant difference in reading gains. In-person students attended more consistently, so routine matters online. See our guide to online vs in-person tutoring.

When does tutoring work less well?

• Infrequent sessions, such as once every week or two.
• Large groups, where the tutor cannot focus on each child.
• Untrained or inconsistent tutors.
• Missed sessions, since benefits depend on attending regularly over weeks and months.
• No link to school, so tutoring and class pull in different directions.

How long before you see benefits?

Most families notice changes in confidence and homework within a few weeks: fewer tears, more "I get it." Measurable gains in skills usually show within one to three months of regular sessions. Grades can take longer, because they reflect a whole term of work. Ask the tutor to set two or three specific goals at the start, so you can see progress before report cards arrive.

How do you get the most from tutoring?

1. 1Aim for two or three sessions a week, not one.
2. 2Choose one-to-one if your child has specific gaps.
3. 3Share schoolwork so lessons match class topics.
4. 4Protect attendance; treat sessions like a fixed appointment.
5. 5Ask for regular progress updates, and check them.
