How to tell if your teenager is actually revising

The short answer: look at output, not input

The single reliable test of revision is whether something comes back out of your teenager's head without the notes in front of them. Everything else — hours logged, highlighter usage, a beautifully colour-coded timetable, a bedroom door that has been shut since four o'clock — is input, and input is a poor guide to what is actually being learnt.

This matters because the most common revision failure is not laziness. It is a teenager working hard at a method that feels productive and does very little. Re-reading a chapter, copying notes out neatly, watching a video with the subtitles on: all of these produce a strong sense of familiarity. Familiarity is not the same as being able to retrieve something in a silent exam hall in June, and the gap between the two is exactly where confidence collapses after a mock.

So the question is not "are they at the desk?" It is "can they do anything with the material when the desk is taken away?" That question can be asked kindly, in the kitchen, in five minutes, and it does not require you to check anyone's screen time.

What real revision actually looks like

Effective revision is uncomfortable and looks a bit unimpressive. Research on study techniques — Dunlosky and colleagues' well-known 2013 review is the usual reference point — consistently finds that two strategies outperform almost everything else: practice testing (trying to recall the material rather than review it) and distributed practice (spreading the work out rather than massing it). Highlighting, re-reading and summarising, the three things teenagers do most, come out near the bottom.

In practice, a session that is working tends to have these features:

• Notes are closed for part of it. Something is being written, said or drawn from memory before it is checked.
• There is a source of right answers. Flashcards, past questions, end-of-chapter questions, a friend, a mark scheme — something that tells them whether the recall was correct.
• Mistakes are being found, not avoided. A session with no wrong answers in it was too easy to be useful.
• Old topics reappear. Revising a topic once in October and never again is how it disappears by May. Good revision keeps returning to things that feel finished.
• It is shorter than you expect. Twenty focused minutes of self-testing beats two distracted hours, and it is far more likely to happen again tomorrow.

By contrast, the classic signs of revision that is not working: the notes are always open, everything is being copied out again in a nicer pen, the same favourite topic keeps getting revised because it feels good, and nothing is ever marked.

Five questions that reveal it without an interrogation

Ask about the work, not about the effort. Questions about effort ("have you done enough?", "how long were you up there?") invite a defensive one-word answer, because there is no answer that ends the conversation safely. Questions about content are easy to answer honestly and tell you far more.

1. "What did you do today, out of interest?" — a genuine, unloaded question. "Enzymes" is a good answer. "Revision" is not.
2. "Go on then, teach me it." Explaining something aloud to a non-expert is retrieval practice in disguise, and you will hear the gaps immediately. It also gives them a win, which is rarer than you think.
3. "What did you get wrong?" If they can name a mistake, they have been testing themselves. If the answer is "nothing", nothing was tested.
4. "What is the hardest bit of that topic?" A student who has really worked a topic has an opinion about which part is horrible. A student who has read about it does not.
5. "When are you next doing this one again?" This asks about spacing without using the word. A shrug is fine information; it tells you the plan is missing, not that the effort is.

Time at the desk versus retrieval practice

Hours are the metric families reach for because they are the only one visible from outside a closed door. They are also the metric most easily faked, sometimes without any intent to deceive: a teenager can be genuinely present at a desk for three hours and retrieve nothing.

A more useful frame is that revision has two halves, and only one of them is optional. The first half is exposure — reading, watching, listening, making the notes. The second half is retrieval — shutting the book and getting it back out. Almost every student does the first half. The students who improve are the ones who do the second, and it is the second half that hurts, which is precisely why it gets skipped.

If you want one number to care about, make it "how many times has this topic been tested", not "how many hours has this subject had". The Education Endowment Foundation's guidance on metacognition and self-regulated learning makes a related point that is worth holding onto: students are generally poor judges of their own learning, and they need to be taught to plan, monitor and evaluate their work rather than simply told to do more of it.

How to help without taking over

Your job is to make the good method easier, not to run the revision. The moment you own the timetable, they stop owning the outcome, and the arguments start.

• Offer to be the tester. You do not need to understand the subject. Reading a question off a card and saying "not quite, try again" is genuinely valuable, and it is the one job a parent can do without expertise.
• Protect the conditions. A charged laptop, a room that is not the kitchen at dinner time, phone in another room for twenty minutes. Removing friction is worth more than any amount of encouragement.
• Ask for the plan, not the hours. "Which three topics this week?" is a better question than "how much are you doing tonight?" — and it produces something you can both check against on Sunday.
• Praise the method, not the mood. "You tested yourself on the bits you hate — that's the right way round" lands better than "well done for working so hard", and it reinforces the behaviour you want repeated.
• Let one bad evening be one bad evening. Revision that survives a bad day is built on a small daily habit, not on heroic sessions. Treating a missed night as a crisis makes the next night harder.

It is also worth saying out loud, once, that you are not going to police it. Teenagers who believe they are being monitored optimise for looking busy. Teenagers who believe the results are theirs sometimes take longer to start, but they start.

When to actually worry

Most "they are not revising" worries are really "they are not revising the way I would". A few are worth taking seriously. The signal is a pattern over two or three weeks, not a single bad Tuesday.

• They cannot name what they did, for several weeks running — not evasively, but genuinely.
• Avoidance is subject-shaped: everything except maths, every time. That is usually fear of a specific topic, and it is fixable with help.
• Mock results are far below coursework and class performance, which points at exam technique or retrieval rather than effort.
• Sleep, appetite or mood have changed, or the work has become frantic rather than steady. Anxiety looks like both laziness and overwork, and both need the same first response: a conversation, not a timetable.
• They have stopped talking about school entirely.

If two or more of those hold, the useful next step is an email to the form tutor or head of year rather than a harder line at home. Schools see the mock data, the classwork and the corridor version of your child, and they will usually tell you plainly whether this is normal Year 11 wobble or something more.

Tools that show progress — and the trust question

Some families want a source of information that is not an interrogation. That is a reasonable thing to want, and there are a few honest options: a shared paper wall planner in the kitchen; a weekly ten-minute review where they show you what they got wrong; your school's existing parent portal, which usually carries attendance, homework and assessment data you may not be using; or an app that shares progress with you.

Most revision apps do not share anything with parents at all — Quizlet, Anki and Seneca are built around the student's own account. We compare what each one actually exposes in Revision apps parents can see progress in.

FacilStudy, the app we are building, takes a deliberate position on this. A student photographs their notes, gets a study pack and a fifteen-minute daily plan, and can invite one adult as a Study Partner. That adult sees the streak, time studied this week, mastery per subject, topics needing attention and upcoming tests. They do not see tutor conversations, the photographs, or individual answers. The invitation comes from the student, and the student can revoke it at any time from the app. It is on the Plus tier (£4.99 a month); the free tier gives five scans a month and the daily plan with no partner view. FacilStudy is pre-launch — there is a waiting list and more for families at the parents page.
