The difference between a tutor who keeps students for three years and a tutor who loses them after six weeks is almost never subject knowledge. It's structure. A well-structured hour leaves the student feeling like they made visible progress. A poorly structured hour feels like a homework club with an adult watching.
Here is a session structure that works across levels, backed by how memory and learning actually function. You can adapt it for Year 3 phonics or A-Level Further Maths — the ratios change, the skeleton doesn't.
The 60-minute template
For a one-hour session, the split that works best is roughly:
- 5 min — Arrive, settle, recap last session
- 10 min — Retrieval practice on prior content
- 25 min — New teaching / main lesson block
- 15 min — Guided practice and consolidation
- 5 min — Set homework, plan next session
If you take nothing else from this page, take that 10 minutes of retrieval practice near the start. It is the single biggest lever you have on long-term retention.
Why retrieval practice first, not at the end
Most tutors do retrieval at the end of a session — a quick recap before the student leaves. That's the wrong time. The student has already absorbed the new content, so recapping it is easy, and “easy” is not how memory is built.
The research (Roediger, Karpicke, Bjork — the three names to know if you want to read the original papers) is unambiguous: retrieval is more effective when it's spaced and effortful. Ten minutes into the session, from a cold start, asking a student to reproduce last week's content without notes is what actually moves it into long-term memory.
Practically, this looks like:
- Three or four quickfire questions on last session's topic. Written, not spoken — writing forces commitment.
- One slightly older question from 2-3 sessions ago. This is where the spacing happens.
- One harder synthesis question that links the last two topics.
If a student gets any of these wrong, that's valuable. You now know what to re-teach. If they get everything right, you know the prior content is holding — you can move on confidently.
The main teaching block: 25 minutes, not 50
A common new-tutor mistake is teaching for 40-50 minutes and giving 10 minutes at the end for the student to “have a go”. This inverts the optimal ratio. Students remember what they do, not what they hear.
Cap your explanation at 25 minutes. Inside those 25 minutes, use a variant of the I-do / we-do / you-do model:
- I do (5-7 min). You work through one worked example out loud, showing every step including the bits you normally skip. Narrate your thinking, not just your writing.
- We do (10 min).A second example where the student drives and you prompt. Ask “what do you do next?” before every step. Catch mistakes in the moment, don't wait until the end.
- You do (8-10 min).A third example they do alone while you watch silently. This is the diagnostic — if they can't do it alone, they haven't learned it, and the you-do phase tells you exactly where it's broken.
Cognitive load theory explains why this works: by breaking a complex skill into progressively more-independent attempts, you keep the student in the productive-struggle zone without tipping into overwhelm.
Consolidation: the 15 minutes most tutors waste
Between the main teaching block and the end of the session sits 15 minutes that most tutors use for “extra practice”. This is fine but underpowered. Use those 15 minutes for one of these three things, depending on the student:
Past paper question. For GCSE and A-Level, 15 minutes is exactly long enough for one exam-style question under timed conditions. Do this every session and you normalise exam pressure. By April of their exam year the student is no longer frightened of timed questions.
Teach-back. The student explains the new topic back to you as if you were a confused friend. This is the Feynman technique in miniature. Gaps in understanding are ruthlessly exposed when the student has to generate the explanation in their own words.
Error analysis. Give them a worked solution with a deliberate mistake and ask them to find it. This builds the meta-skill of checking their own work, which wins more marks in exams than any additional content.
Setting homework in the last 5 minutes
Homework is where most tuition falls apart. Tutors set too much, parents don't enforce it, the student does half, both sides get quietly frustrated.
The rule: homework should take 20-40% of the session length. For a 60-minute session, 15-25 minutes of work at home is enough. Any more and you'll start getting excuses instead of work.
Be specific about what “done” means. “Practise quadratics” is a dead instruction. “Complete questions 1-6 on the attached sheet. If you get stuck, note where and we'll start there on Tuesday” is alive.
Write the homework down where the parent will see it, not just where the student will. A short end-of-session message to the parent — “today we covered completing the square; homework is questions 1-6 on the attached sheet, should take about 20 minutes” — does more for retention than any amount of extra teaching.
Adapting the template by age and level
Primary / KS2
60 minutes is too long for most primary-age students. Either cut the session to 45 minutes or keep it at 60 with the ratios weighted differently: more retrieval (less new content held in memory yet), shorter teaching blocks, more games and fewer past papers. For 11+ specifically, work up to full 30-minute timed papers by the autumn of Year 5 — anything earlier and you exhaust the child.
KS3 / GCSE
The template above is designed for this level. The only adjustment: in the run-up to mock exams, drop the teaching block to 15 minutes and extend the past-paper block to 25. From March of the exam year onwards, a session is essentially 20 minutes of retrieval, 35 minutes of past-paper questions under timing, and a debrief. You're simulating the exam, not teaching new content.
A-Level
Stretch the main teaching block to 30 minutes — A-Level content is denser and students can hold focus longer. But extend the session too: 90 minutes is the sweet spot for A-Level Maths, Further Maths, and Physics. Two 45-minute halves with a 5-minute break in the middle outperforms one continuous 90-minute block.
Adult learners / professional tuition
Flip the ratios again: adults typically come with specific gaps they want closed. Less “I do”, more “you do”. Start with a diagnostic question, let them work, intervene only when needed. Adults learn by doing under pressure and don't need you to model as much as younger students.
The three things that wreck sessions
Letting the student drive the agenda.“What would you like to work on today?” sounds student-centred. It isn't. Students don't know what they don't know. You plan the session based on their last session's gaps; they tell you if they have a specific homework panic that needs inserting.
Going over time. A 60-minute session that routinely runs to 75 trains the parent to expect it for free and devalues your rate. End on time. Every time.
Talking too much.Record yourself for one session. If you're talking for more than 50% of the hour, you're in teach-mode when you should be in practice-and-correct mode. Students cover more content when they do more and hear less.
Session notes: the part nobody does, everyone should
At the end of every session, write 3-5 lines: what you covered, how the student did, what to start with next time, anything parent-relevant. This is what makes retrieval practice possible next week — without notes you're guessing, and guessing is how topics drop out of a student's active memory.
Good session notes also turn into parent reports in minutes instead of hours, and into evidence if you ever need to demonstrate progress to a parent who's wavering on whether to continue.
If you're doing this on paper, that's fine. If you'd like notes, lesson plans, retrieval questions and parent reports to be in one place and automatically reusable across sessions, TutorLab's free plan is built for exactly this workflow — 3 students free, no credit card.
