Every school has a version of the same scene. A TA sits beside the same child, in the same seat, for every lesson, every day, term after term. It looks like support. Ofsted inspectors used to nod approvingly at it. Parents often ask for it by name. And for years, most of us assumed it was simply good practice – more adult attention for the pupil who needs it most has to be a good thing.
The evidence says otherwise, and it’s worth taking seriously because it comes from an unusually solid place. The Education Endowment Foundation’s guidance report Making Best Use of Teaching Assistants is built on a systematic review of the research base on TA deployment – not opinion, not a training company’s sales pitch, but a synthesis of what actually happens to pupils’ outcomes under different models of support. Its conclusion is blunt: the way most schools have drifted into deploying TAs is quietly working against the pupils it’s meant to help. The fix isn’t more training days on “TA skills” in the abstract. It’s a handful of specific, practical changes to how you brief, position and work alongside the TA in your room. This is what those changes look like.
What the evidence actually found
The EEF’s language for the default pattern is the “Velcro” model – a TA effectively stuck to one pupil or one small group, for extended periods, lesson after lesson. It happens for good reasons. A child is struggling, an adult is available, and putting the two together feels like the responsible thing to do. But the report traces what that pattern does over time: it quietly separates the pupil from the classroom teacher, from the pace and content of whole-class teaching, and often from their peer group as well. The pupils who most need expert teaching end up getting the least of it, mediated instead through an adult who is warm and well-intentioned but, in most cases, not trained as a teacher.
The report’s first recommendation states this as plainly as guidance reports ever do: TAs should not be used as an informal teaching resource for low-attaining pupils. The principle underneath it is one worth pinning above your desk – pupils who struggle most should get at least as much time with the teacher as everyone else in the room, not less. If a TA has a direct instructional role, the expectation is that they add value to what the teacher is doing, not quietly substitute for it.
None of this is an argument against TAs. The same evidence base is just as clear that well-deployed TAs move the needle. Structured, short, well-resourced interventions delivered by trained TAs are associated with roughly three to four additional months of progress on average – five months in primary, slightly less in secondary, and a little lower for primary maths specifically. But that figure comes with a condition attached, and it’s the condition most schools skip: those gains only show up when TAs work in structured settings with proper training and support. Put a TA into an informal, unsupported instructional role and the same evidence shows the effect can turn negative. The tool isn’t the problem. How you deploy it is.
Briefing that takes five minutes, not fifty
Ask most TAs what they find most frustrating and you’ll hear some version of the same answer: they walk into lessons not knowing what’s actually being taught, what the class already covered last week, or what “success” looks like for the pupils they’re about to support. They improvise. Sometimes the improvising is excellent. Often it means a TA quietly reteaching a method the class moved on from, or giving help that undercuts what you’re trying to achieve.
The EEF guidance is specific about what a TA needs to know before a lesson starts, and it’s a shorter list than you’d think:
- the concepts, facts or information being taught
- the skills pupils are meant to learn, apply, practise or extend
- the intended learning outcomes – what “getting it” looks like
- what feedback you want them to give, and in what form
None of that needs a formal meeting. Most schools that do this well have simply found small, protected pockets of time rather than waiting for one that never appears: a TA arriving fifteen minutes before the bell, a slice of PPA time spent together rather than apart, five minutes at the end of assembly, or a plan left on the TA’s desk the day before with the outcomes and the “watch out for” pupils flagged. What matters is that it happens consistently, not that it’s elaborate. A TA who knows the intended outcome for a lesson can adapt on the fly when a pupil goes off-script. A TA who’s guessing can only ever follow, and following usually means doing the task for the child rather than teaching them to do it themselves.
Building independence, not dependency
This is the part of the guidance that changes classroom practice the most once teachers actually see it in action, because it runs against instinct. The instinct, when a child is stuck, is to help. The evidence says the specific shape of that help is what determines whether it works.
TAs who get the best outcomes are trained to give the least amount of help first, not the most. That means waiting – genuinely waiting, past the point that feels comfortable – before stepping in, so the pupil has a real chance to attempt the next step alone. It means prompting rather than telling: “what do you notice about the first sentence?” rather than reading it for them, “what’s the first thing you need to work out?” rather than working it out and reporting the answer. It means resisting the pull toward task completion. A page of finished, correct work that the pupil didn’t really do themselves feels productive in the moment and is close to worthless six weeks later, because the pupil hasn’t built the skill of doing it unsupported.
Talk quality is the mechanism the research keeps coming back to. A TA who narrates, corrects and fills silences is, without meaning to, training a pupil to wait for the adult rather than think for themselves. A TA who asks a genuine question and then holds the silence is teaching the opposite lesson. It’s a harder skill than it sounds, and it’s one worth explicitly naming and practising with your TA rather than assuming it’ll happen on its own. “Give them the least help that gets them moving” is a good one-line brief to leave on a desk.
Why permanently parking a TA with the same pupils stops working
The Velcro pattern doesn’t just weaken teaching contact. It has quieter costs that build up over a term. Pupils who always have an adult beside them stop being expected to raise a hand, ask a peer, or try before asking – because they’ve learned, correctly, that help is always one seat away. Other pupils notice which children get the permanent adult, and that visibility can do real damage to how a child sees themselves in the room, particularly by Year 5 or 6 and well into secondary. And practically, a TA fixed to one pair of pupils for the whole day has no capacity to respond to whoever actually needs support in a given lesson, which is rarely the same two children every time.
Rotating support instead doesn’t mean abandoning pupils with the greatest need. It means designing deployment around the lesson rather than around a name on a list. In practice that looks like a TA circulating the room rather than parked at one table, dipping in for focused two-minute check-ins with different pupils across a session, taking a different small group for the guided part of each lesson depending on that week’s assessment, or team-teaching a starter so that support isn’t visibly tied to one child at all. Some schools rotate which pupils get TA-led small-group input across the week on a simple timetable, so the same two or three children aren’t always the ones being pulled aside. It takes more planning up front than leaving the arrangement on autopilot. It also means a pupil who’s had a good run of independent work for a fortnight can be given room to keep going, instead of an adult continuing to sit with them out of habit.
What a TA should – and shouldn’t – be doing while you teach the whole class
Whole-class input is where the Velcro habit is most visible and most easily fixed, because it’s largely about positioning and role clarity rather than anything requiring extra training.
What tends not to work: a TA sitting beside one pupil for the entire input, quietly repeating or translating every sentence you say in real time, which trains that pupil to tune out the teacher and tune into the TA instead. Equally unhelpful is a TA who becomes the de facto behaviour manager for a single child, stepping in at the first fidget, because it removes your ability to address behaviour as part of normal classroom routine and singles the pupil out to the rest of the room. And a TA who spends whole-class time doing paperwork, photocopying, or prepping the next activity because “the input doesn’t need me” is a wasted resource – there’s almost always a more useful five minutes available.
What works better: a TA who scans the room during input, picking up the two or three pupils anywhere who look lost rather than fixing on one seat. A TA using a whiteboard or visualiser to model note-taking or key vocabulary alongside you, so support is built into the lesson rather than bolted onto one child. A TA who notes misconceptions during independent work and feeds them back to you at the end, rather than fixing them silently one pupil at a time, so the pattern actually reaches your planning. A TA who moves physically – near the back for input, near pupils who need proximity during independent work, out of the way when a pupil clearly doesn’t need anyone hovering. None of this requires the TA to know less about the lesson. It requires the opposite: the briefing described above is what makes this kind of flexible, room-wide support possible in the first place.
Structured interventions: the other half of the job
Everyday classroom support is one half of what the evidence covers. The other is what happens when a TA takes a pupil or small group out for a dedicated intervention, and here the guidance is unusually precise about what separates an intervention that works from one that doesn’t.
Effective interventions share a shape: sessions are short (often 20–50 minutes), delivered frequently (three to five times a week), and sustained over a defined block (eight to twenty weeks) rather than run indefinitely. TAs delivering them have had real training in that specific programme, not a general TA induction. The intervention has structured materials and a clear plan that the TA follows closely rather than adapting on instinct, and it’s targeted using assessment data so the right pupils are getting it, not just the pupils who happen to be free at that time. Crucially, the report is explicit that interventions are too often run in isolation from classroom teaching, with pupils left to work out the connection themselves. They usually can’t. Someone – teacher or TA – has to make the link between what happened in the intervention room and what’s happening back in class, or the extra time is largely wasted.
If you’re running or overseeing interventions, that’s a reasonable checklist to hold any programme against, whether it’s a scripted commercial scheme or something built in-house. And if a pupil is picking up support from more than one adult across the week – a TA-led intervention, in-class support, maybe a homework club – it helps enormously if everyone involved can see the same plan for what that pupil is working on, rather than each adult reconstructing it from memory. Tools like Learnaroo Hub’s resource-assignment features exist for exactly that kind of coordination, so a teacher and TA are working from the same page for a pupil rather than two different ones.
The working relationship underneath all of it
None of the above holds up without a decent working relationship, and it’s worth being honest that this is often the part schools invest in least. A TA who is treated purely as an extra pair of hands – told what to do at the classroom door with no context and no chance to feed anything back – will, quite reasonably, default to the safest possible interpretation of their role: sit with the child, keep them quiet, keep them working. That’s not a TA problem. It’s what happens when someone is given responsibility without information or voice.
TAs typically spend more one-to-one time with individual pupils than the class teacher does, and that means they often notice things first: a pupil who’s started struggling with reading fluency, a friendship breaking down, a home situation showing up in behaviour. A working relationship built on genuine two-way communication treats that as useful information, not as the TA overstepping. In practice that means asking rather than only telling, taking two minutes at the end of a session to hear what the TA noticed, and being willing to adjust a plan because a TA flagged something that wasn’t obvious from the front of the room. It also means being upfront when something a TA is doing isn’t working, in the same collegial way you’d want feedback yourself – specific and kind, not left to fester.
Mutual respect here isn’t a soft add-on to the evidence above. It’s the condition that makes the evidence usable. A brief only works if the TA trusts it’s worth following. Independence-building only works if the TA believes you’ll back them when a parent asks why their child isn’t getting one-to-one help every lesson. Rotation only works if the TA isn’t quietly worried that spreading their attention looks like they’re doing less. All of that comes from being treated as a professional partner in the classroom, not a supervised extra.
Where to start on Monday
You don’t need a whole-school policy rewrite to change how this works in your own room. Pick one thing. Start briefing your TA on the four “need to knows” before Monday’s lessons, even if it’s a scribbled note rather than a meeting. Watch where your TA sits during your next whole-class input, and move them if they’re parked beside the same pupil out of habit rather than need. Ask your TA, this week, what they’ve noticed about a pupil that you haven’t – and actually use the answer. The EEF’s evidence is consistent on one point above all the others: TAs make a real difference to outcomes when they’re deployed with the same intentionality as any other teaching decision, and very little difference, or a negative one, when they’re not. That’s a decision teachers get to make every single lesson, not once a year in a staff meeting.
