| Feature | Small-group | One-on-one |
|---|---|---|
| Attention | Shared, but platform tailors practice to each child | Undivided — fully focused on one student |
| Pace | Group pace, with individual practice on the platform | Fully tailored to the student |
| Peer benchmarking | Yes — see where you stand among peers | None — no peer comparison |
| Exam-like conditions | Closer — working alongside others | Quieter, one-to-one setting |
| Value | Stronger — shared teaching cost | Higher cost per session |
| Personalisation of practice | High on a strong platform — adaptive and tracked | High — driven by the tutor |
This is one of the oldest questions in tutoring, and the traditional answer is a straight trade-off: one-on-one buys attention, small-group buys value. That’s still broadly true — but a strong platform changes the maths, so it’s worth thinking it through properly rather than assuming 1:1 always wins.
What one-on-one does well
Undivided attention and a fully tailored pace. In a 1:1 session, everything bends to one student — the tutor can slow down on a sticking point, skip what’s already mastered, and respond in real time. For a child with specific, stubborn gaps, or one who needs close reassurance to stay confident, that focus is genuinely valuable. The cost is that it’s the most expensive option per session, and it removes peer benchmarking entirely — your child never sees where they stand against others sitting the same test.
What small-group does well
Peers and value. A small group costs less because the teaching is shared, and it adds two things 1:1 can’t: benchmarking against other students, and conditions that feel closer to a real exam room. Sitting and competing alongside peers is, after all, much more like the actual selective test than a quiet one-to-one room. The classic weakness is shared attention — and that’s exactly the gap a platform closes.
How a strong platform changes the trade-off
The usual argument for 1:1 is personalisation. But a genuine adaptive platform delivers much of that inside a small group. On the Test Academy platform, each child works through practice tailored to their level, marking is instant, and analytics track individual progress — so a student gets personalised, data-driven practice and peer benchmarking at the same time. Writing is marked criterion-by-criterion for every child, which is the kind of consistent, granular feedback that’s hard to sustain by hand.
That’s the shift: the historic weakness of group tutoring — diluted attention — is largely offset when the platform personalises the practice. You keep the peers, the exam-like conditions and the value, without giving up tailored feedback.
The way we’d frame the decision
If your child needs intensive, individual support for a specific problem, 1:1 has a real place. For most students preparing for selective, a well-run small group built on a strong platform — like our Selective Mastery program — offers the better balance of personalisation, benchmarking and value. Our take on whether selective tutoring is worth it goes further on getting value from the spend.
