Group or one-to-one private tutoring: advantages, limits and price

1. The educational differences between group and one-to-one tutoring

In a one-to-one session, the whole session can be built around a precise diagnosis. If the student has mastered the first part of the chapter but is stuck on a particular step, the tutor can move straight to it, change the example, slow down or speed up without having to keep to a shared pace.

The Education Endowment Foundation defines one-to-one tuition as intensive support given to a single student. Its summary highlights in particular its value when support is targeted at identified difficulties and linked to the work done in class. It also points out that direct comparisons with very small groups give mixed results: in some studies, one-to-one does better; in others, groups of two or three students achieve similar or better results.

Groups work differently. The tutor has to build a session that is shared enough for several students to work together. The EEF defines small-group tuition as tutoring that brings together two to five students and stresses that its effectiveness depends in particular on targeting suited to the participants’ needs.

Criterion	One-to-one session	Small-group session
Content	Can be changed at any time for a single student.	Has to stay relevant for several students.
Pace	Fully adapted to the student.	A compromise between the paces within the group.
Diagnosis	Very detailed: every mistake can be followed up immediately.	Possible, but the tutor has to share their attention.
Interaction between students	None during the session.	Can allow explanations, comparison of methods and mutual help.
Cost per student	Generally higher.	Can be lower by sharing the cost of the tutor or through a group package.

2. Speaking time and personalisation: what the number of students really changes

In a one-to-one session, when a student asks a question, the tutor can devote the next ten minutes to it if necessary. In a group, this is less easily done: the progress of the others also has to be protected.

The difference is not simply arithmetic, however. In a group of four, you cannot say that each student “gets exactly fifteen minutes” out of an hour. Part of the session can be shared, an explanation aimed at one student can benefit the others, and participants can learn by comparing their reasoning.

On the other hand, the tutor’s exclusive attention is necessarily shared. This matters when the student needs:

• to go back over very specific gaps;
• to be prompted at every step of a line of reasoning;
• a pace very different from that of their school level;
• to work on a piece of marked work, an assignment or a method specific to their situation;
• to speak a lot, for example when preparing for an oral exam.

Conversely, if several students are working on the same goals and are at fairly similar levels, a small group can keep support targeted while sharing the session.

Group size matters, but it is not the only criterion

The word “group” can mean two students or a dozen. These situations do not give the tutor the same ability to observe each one. In its summary on small-group tuition, the EEF works mainly on groups of two to five students and notes that beyond six or seven participants, average effectiveness falls noticeably in the studies examined. This does not mean that a group of eight would necessarily be bad: the quality of teaching, how similar the needs are and how participation is organised remain decisive.

For a family, then, the number of students advertised is not enough. Also ask whether the group is formed by school level, by subject, by goal or simply by availability. Four Seconde (first year of lycée) students preparing the same chapter on functions do not offer the same teaching situation as four students at different levels who have come to do their homework.

Perfect uniformity is not necessary, however. A little diversity can enrich the discussion. The problem arises when the goals become incompatible: if one student needs to go back over fractions while the others are already working on quadratic equations, the tutor has to choose between two progressions that are hard to reconcile.

3. Motivation, emulation and social pressure

A group brings something that one-to-one cannot reproduce exactly: other students are present. Hearing a question you had not thought of, explaining a method to someone or comparing two lines of reasoning can enrich the session.

The EEF summary on collaborative learning observes positive effects on average, but insists on one condition: group work has to be structured. Simply putting several students in a room does not automatically create collaborative learning. The tasks must push everyone to take part and to articulate their reasoning.

This nuance is essential for academic support. A group can motivate a student who enjoys discussion and sees that they are not alone in hesitating. It can also reduce the involvement of a quiet student if two participants constantly answer for them.

Emulation is only useful if it remains educational

A little competition can sometimes boost engagement, but the EEF stresses that an excessive focus on competition can distract from the real learning goal. A worthwhile group quiz therefore asks “how did you reason?” rather than just “who answered fastest?”.

For a very reserved student who already does not dare flag what they do not understand in class, one-to-one can offer an easier space for asking questions. Conversely, a student who relies heavily on the adult can sometimes benefit from a well-structured group in which they have to explain their approach and listen to that of others.

4. Cost per student: how to compare without mixing up different offers

Groups have a structural economic advantage: the cost of the tutor can be shared between several participants. But the actual saving depends on the pricing model. Some tutors set a total price for the group; others charge an amount per student; agencies may sell monthly packages or holiday courses.

Theoretical example: a tutor charges the session to the group

Suppose, purely to illustrate the calculation, that a tutor charges €48 for one hour one-to-one and €72 for one hour with a group of four students.

• One-to-one: €48 per student per hour.
• Group: €72 ÷ 4 = €18 per student per hour.
• Difference: €48 - €18 = €30 less per student.

In this example, the group reduces the cost per student by 62.5%. This figure is not a market average: it depends entirely on the assumptions chosen.

Theoretical example: pricing directly per student

A tutor may also offer €45 one-to-one and €25 per student for a group. With four students, they then charge €100 in total. Each family pays less, while the tutor earns more from the session than with a single student. This is one of the economic mechanisms that make group sessions possible.

An example of an offer actually advertised in September 2026

By way of illustration, and not as a national average, Acadomia currently advertises weekly group classes in Île-de-France in groups of six or eight students at most, with sessions of 1 hour 40 minutes or 2 hours a week, from €76 per month. The package, region, length and number of sessions mean this price cannot be compared directly with an individual hourly rate.

To compare two offers, bring the prices back to a genuinely comparable basis: number of hours planned, number of students, compulsory fees, length of commitment and any applicable tax benefits. For market rates more broadly, our article on the price of private tutoring in 2026 deals specifically with this question.

Compare the price with what the student will actually use

The price per hour is not the only useful calculation. Imagine a one-to-one offer at €45 for an hour and a group offer at €18 per student for two hours. The group option looks much cheaper: €9 an hour against €45. But this comparison does not yet answer the educational question. If the student is working on exactly the same goals as the group, the two hours can be very good value. If they spend much of the session on concepts they have already mastered or that are too far removed from their difficulties, the low hourly cost loses part of its appeal.

Conversely, an expensive one-to-one hour is not automatically “better value”: if the session is poorly prepared or generic, theoretical personalisation is not enough. The right calculation therefore combines budget and fit with the need. Ask what will be worked on, how the groups are formed and how the tutor checks each student’s progress.

5. Which format to choose depending on the subject

There is no rule along the lines of “maths = one-to-one, languages = group”. The right format depends more on the task to be accomplished.

Maths and Physics and Chemistry: a small group can be relevant when students are working on the same chapter and can compare several methods. One-to-one becomes particularly useful if the student has gaps that differ from the rest of their level, or if their reasoning needs to be followed precisely step by step.

Languages: a group makes it possible to multiply conversation partners, dialogues and communication situations. One-to-one, on the other hand, gives the same student more speaking time and makes it easier to correct their pronunciation or mistakes in a very targeted way.

French, Philosophy, SES (Economic and Social Sciences) or History and Geography: group work can be rich for comparing arguments, outlines or interpretations. One-to-one is better suited when a personal piece of work needs detailed correction or a very specific writing method needs to be revisited.

The EEF data also point out that results vary between subjects and programmes. It would therefore be going too far to present one format as inherently better for an entire subject.

6. Which format depending on the student’s profile

The choice becomes clearer when you start from how the student actually behaves.

Profile or need	Format that is often relevant	Why
Very specific gaps	One-to-one	The content can follow the student’s mistakes exactly.
Independent student with a goal shared by others	Small group	Group time can remain effective without needing constant prompting.
Student who does not dare ask questions	One-to-one, at least to begin with	A one-to-one relationship can make it easier to voice what they do not understand.
Student motivated by discussion	Small group	Other students’ reasoning becomes a learning resource.
Need to correct personal work	One-to-one	The session can be devoted entirely to the student’s work.
Very tight budget	Small group, to be compared	The cost per student can be significantly lower.

These pairings are not prescriptions. An excellent tutor can run a highly individualised group; a poor one-to-one session can remain passive and generic. The quality of the diagnosis, explanations, exercises and follow-up matters more than a simple format label.

7. Can group and one-to-one tutoring be combined?

Yes, and it is sometimes the most rational compromise. A student can attend a regular group class to work on the shared curriculum, then use an occasional one-to-one session when a specific blockage appears or before a particular deadline.

You can also do the reverse: a few one-to-one sessions are used to go back over prerequisites, then a group becomes enough once the student reaches a more even level of work.

This combination avoids paying for one-to-one tutoring for tasks that genuinely benefit from a group, while keeping the option of very personalised help when it brings real value.

What NOEO offers: one-to-one online support

NOEO currently offers 1-to-1 online private tutoring. The tutor can therefore focus the session on the student’s goals, documents, mistakes and pace in NOEO Live. After the session, the session report keeps a structured educational record and, when recording has been authorised, the replay of the session remains available for 3 months.

This choice of one-to-one does not mean that group tutoring is educationally poor. The research cited above shows precisely that well-designed small groups can be effective. NOEO’s positioning meets a different need: keeping a human tutor entirely focused on one student and extending that follow-up between sessions.

To understand how this support works in practice, the How it works page sets out the journey before, during and after a session. To compare online and in-person tutoring specifically, our article on online or in-home private tutoring deals with that separate decision.

How to decide in five questions

1. Is the student’s problem very specific? The more the answer is yes, the more valuable one-to-one becomes.
2. Do they need to speak a lot or to be prompted? The tutor’s exclusive attention may become decisive.
3. Do the other students in the group really have a compatible goal and level? A homogeneous group is easier to target.
4. Does the student learn well through discussion with peers? If so, group work has an advantage that one-to-one does not offer.
5. What is the full cost for a genuinely comparable hour or month? Compare the volume of sessions and the fees, not just the headline price.
