Private tuition or group classes — what actually helps a child improve?

If you've decided some form of external help is right for your child, the next question is what shape it should take. Private one-to-one tuition and group classes are both popular, but they work in very different ways — and they suit different children. Picking wrong wastes money, but more importantly wastes time you don't have.

This post breaks down the actual differences, with no axe to grind.

How they actually work, in practice

Private one-to-one tuition is typically a 60-minute session in your home (or the tutor's), once a week. The tutor reviews the previous week's practice, identifies a specific weakness, teaches a technique, and sets homework. The cadence is usually weekly, sometimes twice a week in the run-up to the test.

Group classes come in two shapes:

• Tuition centre group sessions — usually 6–12 children, 1.5–2 hours, weekly, working through a fixed curriculum. Often comes with weekly homework that's reviewed at the start of the next session.
• Small private group — 2–4 children with one tutor in a private setting (a tutor's home, occasionally a parent's). More intimate, more individual attention, between centre and 1:1 in style.

The honest numbers

| Type | Typical hourly cost | Typical 18-month total | |---|---|---| | 1:1 private tutor | £30–£60 | £3,000–£4,500 | | Small private group (3–4 kids) | £15–£25 per child | £1,500–£2,500 | | Tuition centre (8–12 kids) | £10–£15 per child | £1,200–£2,000 |

Beyond cost, also consider the time tax: weekly sessions plus homework plus travel. Tuition centres often eat 3+ hours of family time per week. 1:1 in your home can be done in 60 minutes flat.

What 1:1 tutoring is genuinely good at

Three things a good 1:1 tutor does that nothing else does as well:

1. Diagnosing individual mistakes. A tutor watching one child closely can spot whether the problem is misreading the question, careless arithmetic, or genuine concept gaps. That diagnosis directly shapes the next session.
2. Pace calibration. They can speed up when your child is grasping a concept quickly and slow down on what's actually hard. A group class moves at the group's pace.
3. Emotional management. A tutor who knows your child for months can navigate their specific anxieties — the kind that come out as tears over a NVR question they could do yesterday.

1:1 is also the more flexible format. Sessions can be rescheduled, focus can shift week-to-week as new weaknesses surface, and the tutor can adapt their style to your child.

What group classes are genuinely good at

Three things groups offer that 1:1 doesn't:

1. Social motivation. Some children work harder when they can see their peers working hard. Sitting in a room with 8 other kids doing the same exercise makes practice feel normal rather than imposed. For a child who resists solo practice at home, this alone can be transformative.
2. Pressure familiarisation. A timed exercise in a group, with the visible signal of other children writing, replicates a real exam environment better than 1:1 ever can. By the time of the actual test, your child has had dozens of "exam-like" experiences.
3. Lower cost per hour. Especially valuable if you want a long preparation runway. Two years of group classes can cost less than six months of 1:1.

Where each fails

1:1 fails when: the tutor isn't a good fit (this happens — find another one), or when the child works well alone with the tutor but freezes in group exam conditions. Some children develop a comfortable rhythm with a familiar tutor that vanishes when surrounded by strangers in the test room.

Group classes fail when: your child is significantly ahead or behind the group's pace. A child who's already mastered the curriculum the group is doing wastes hours. A child who's struggling with foundations the group has moved past gets left further behind. Group classes only really work when your child is in the middle of the bell curve for that specific group.

Group classes also fail when the curriculum doesn't match your target schools' format. A centre running CEM-style practice for a family applying to GL-format schools is actively counterproductive.

How to pick: a real decision framework

Don't pick based on which is "better in general". Pick based on your child:

Pick 1:1 if your child:

• Has a specific identifiable weakness (one subject, one skill area) that's been resistant to general practice
• Has anxiety around being wrong publicly
• Has a strong existing routine and just needs targeted help on hard bits
• Is academically advanced and at risk of being held back by group pace
• Or: your family budget can stretch and you want maximum control

Pick a group class if your child:

• Won't practise without external structure
• Is socially motivated — works harder when peers are working
• Will benefit from regular timed-exam-like environments
• Is roughly in the middle of the expected ability range for the group
• Or: your family budget is tight and you want a long runway

Pick neither (yet) if your child:

• Is in Year 3 or Year 4
• Hasn't yet built a daily reading habit
• Has never sat a timed practice paper

Children in this last category benefit far more from a few months of consistent self-learning to establish habits, before adding external structure. Spending tuition money on a child who hasn't developed daily practice habits is usually money wasted.

What we see in our own data

Families who get the best results tend to combine self-learning daily practice with occasional, surgical 1:1 sessions — say 5–10 sessions, used to break through a specific block rather than as routine. The daily practice provides volume and habit; the 1:1 sessions provide diagnosis. This combination is meaningfully cheaper than weekly tutoring for two years and often more effective.

If you'd like to see what the "daily practice" part looks like in modern form — adaptive question selection, 10-minute packs that target weak skills, full mocks — our free taster papers are a no-commitment way to try it.

The thing that matters more than format

Whichever format you choose, the single biggest predictor of improvement is consistency. A child who does 20 minutes of practice every weekday will almost always outperform a child who does a 2-hour group class once a week and nothing in between.

Tuition and classes are scaffolding. They make consistent practice easier to maintain. They aren't a substitute for it.
