228 Studies: The Case For Phonics Beyond Key Stage One
The staffroom assumption is that phonics finishes with Key Stage One — by secondary, a pupil stuck on a word needs something else. The EEF's evidence says otherwise: plus five months, High security, and a similar effect for older struggling decoders on a thinner but real evidence base. We test the orthodoxy properly, including the caveat that nearly got stated too confidently, and land on the real distinction: it's about the skill, not the age.

Actions for consideration:
• Next time a pupil freezes on a multisyllabic word in any subject, ask them to chunk it before supplying the word.
• Check whether your secondary intake has any decoding check at all, or whether it's assumed to be "already sorted" by Year 7.
• Keep phonics (decoding) and comprehension strategies (Ep17) as two separate goals on any support plan, not one job.
• When citing the secondary-pupil phonics finding, pair it with the "fewer studies" caveat — don't state it as equally well-evidenced as the primary figure.
• Don't write off phonics past Key Stage One — the evidence tracks the skill gap, not the pupil's age.

Right. Let's get into it. This is the education commute. Both voices on this show are synthesized. The judgment isn't. So, uh, I want to set a very specific scene for you today. Like if you are a teacher listening to this on your way in, you are going to recognize this moment immediately. Oh, absolutely. Yeah. So put yourself in a year nine classroom. It is, um, It's silent reading time, the room is totally quiet, heads are down, and you have this one pupil who is completely stuck on a single word on the page.
Right. And the word is circumference. You are standing there watching this pupil try to tackle it. They're you know sounding out the first syllable whole process Yeah, exactly. They try it once then it tried twice They try three times and then they just stop they give up entirely It is a really painful moment to watch and I mean it happens every single day Yeah, so if you are the teacher standing there watching that people give up on that word. What do you actually do? Well, if we are being completely honest, you just tell them the word And you move on.
I mean, what else are you supposed to do in that moment? Because the orthodoxy -like, the unwritten rule that we are all operating on is that phonics is purely a key stage one thing, right? Oh, 100%. It's a reception thing. This kid sitting in front of you is 14 years old. They are not five. Right. So sounding out letters just isn't the fix at this point in their education, surely. But we have to ask the critical question here, you know. Is that actually true, though, or is that just what it feels like from the front of a year nine classroom?
And that is exactly what I want you to check for us today, because it is the silent assumption of absolutely every secondary teacher I know. It is the operating system we are all running on. Well, let's establish the ground rules for today right now. Quick and honest, same as every week on this show, the reading, the research, and every single judgment call we discuss belong to a serving practitioner. Right. It is not ours to fake. OK, so. Let's state that secondary orthodoxy plainly so we know exactly what we're testing against the evidence.
Go for it. The orthodoxy is this. Phonics is for reception and key stage one. By the time a pupil reaches secondary school, a pupil who is struggling with a word like circumference needs something else entirely. Yeah. They need vocabulary work. They need comprehension strategies. They need absolutely anything but sounding it out. Like they are five years old. That is the assumption. Okay. Well, let's actually test that assumption against the data. Headline first. So we know what we are dealing with. Right. We're looking at the EEF toolkit.
the Education Endowment Foundation, specifically their phonics strand. And the headline number, they report, is plus five months additional progress, on average, against similar pupils without the intervention. Okay, plus five months. I mean, that is the exact same number this show has used for, what, half a dozen other strands we've covered? Yeah, it really is. Five months just seems to be a common benchmark. It is the same number, yes, but you really have to look at the context of this specific number because this one comes with unusually strong backing.
How strong are we talking? We are talking about 228 separate studies. Oh, wow. Yeah. And the evidence security is officially rated as high. That translates to four padlocks out of a possible five. That's massive. It is. And I want to be clear, I am quoting directly from the toolkit this time. This isn't just us doing the arithmetic behind the scenes. Right. That is a huge volume of research. 228 studies is no joke. But if the evidence base is that big, Why did it lose a padlock?
What is the missing padlock for? It's a completely valid question. And the honest ding here is about how the studies were conducted. A large percentage of those 228 studies weren't independently evaluated. Oh, okay. That is why it lost the final padlock. But even with that ding, high is still the absolute strongest security rating this show has carried for a headline number. Fine. I hear you. We have incredibly strong evidence for Phonics working. And I'm not disputing that data for a five -year -old in Key Stage 1.
I accept that entirely. Right. What I am disputing is that this evidence applies to my 14 year old year nine pupil. And here is where it gets genuinely uncomfortable for the secondary orthodoxy we just talked about. Okay. Because I went looking specifically for what the toolkit says about older readers and there is a direct line on it. What does it say? Now, there are fewer studies at the secondary age, genuinely fewer. That is a real fact. Right. But where those studies do exist, the toolkit explicitly states they show a similar average impact plus five months.
Let me just clarify that the exact same effect size in secondary school. The exact same effect size in secondary. Yes, but. And here's the crucial distinction. It is for pupils who are still struggling with decoding specifically. It is not for the whole cohort. It is for the ones exactly like your year nine pupil who is stuck on the word circumference. Okay. Let's unpack the logic of that. So it is not that phonics just magically stops working the moment a pupil turns 11. Right. It is that most secondary pupils simply don't need it anymore.
But the ones who do still need it. They get the exact same benefit from it that a five -year -old would get. You've hit the absolute core of the finding. That is the actual finding in the data, not the assumption that phonics is just for little kids. Wow. It is an intervention that tracks the specific skill which is decoding, not the age of the people. All right. I understand the mechanism, but I'm going to push you on the data right now. Fair enough. because that phrase, similar average impact based on a small number of studies, that is doing a massive amount of heavy lifting in that sentence.
Yeah, it really is. Exactly how many studies make up a small number. I want the figure. I have to be upfront with you. I don't have an exact count for you. Really? Yeah. The toolkit page literally just says the words a small number. It does not give a specific figure. So I will concede that point entirely. Ah. You shouldn't have said same effect size quite that flatly a moment ago. It is the same effect size, but it rests on a noticeably thinner evidence base than the 228 studies behind the main headline.
Well, thank you, because that is the caveat I actually needed to hear, not the overly confident version. Yeah, of course. If we're going to trust the data, we have to know exactly how thick the ice we are standing on actually is. It's a completely fair catch. So let's say it properly and hold all the facts together. It is promising. It is consistent with the primary evidence, but it is genuinely thinner data. All three of those things are true at once. Okay. Even with that caveat accepted, this still leaves my actual year nine problem sitting in the room.
Right. The kid with circumference. Exactly. Let's look at the how of this. Even if phonics could help this pupil, is sounding out the letters really the fix for their comprehension? Good question. Like, does this pupil just end up being able to perfectly pronounce the word circumference without actually knowing what the word means? That right there is the other honest limit of this intervention, and it is explicitly laid out in the toolkit's own words. The toolkit states that phonics improves the accuracy of the child's reading, but not necessarily their comprehension.
It is fundamentally a decoding tool. It requires vocabulary and comprehension work sitting right alongside it, which, incidentally, is exactly the territory we covered in APT 17, not this one. Right, so to map this out clearly, the goal is to decode the word correctly first. but then you still have to tackle the comprehension side of it completely separately. Exactly. You are looking at two entirely different jobs supported by two entirely different strands of evidence. Conflating decoding with comprehension is its own unique mistake. Makes sense. And there is one more crucial data point worth knowing before we leave the headline numbers behind.
What's that? When you look at disadvantaged pupils, FSM eligible specifically, those eligible for free school meals, They show a similar or slightly greater benefit than their peers. Oh, wow. Yeah. So it is not just a case of this works for strugglers generally. It actually holds up and maybe even works better for the exact pupils that schools worry about the most. That is exactly the pattern in the data. Yes. Let's talk about what this actually looks like in practice, because applying this intervention isn't going to look the same everywhere.
No, definitely not. Let's explore the same idea. in three different rooms. Okay, sure. If we start in a primary setting, it could look like exactly what it already is in most year one classrooms right now. Right. The screening check itself is systematic, it is structured, and there is absolutely nothing new needed there. But if you take that same idea into a secondary room, it might mean building a five -minute decoding check straight into the very first English lesson of the year seven intake. Yeah. Exactly. You do that to catch those circumference pupils immediately rather than assuming everyone arrives fluent.
You want to catch them before they have spent two years being quietly told to just guess the words they don't know. And if you look at a specialist setting, it could mean treating decoding and comprehension as genuinely separate goals on a pupil's plan. Right. It means celebrating accurate decoding as real, tangible progress in its own right, rather than only counting it as a win once they're Hension catches up, too. And to be clear to you listening, none of that is the evidence trying to dictate or tell one specific classroom exactly what to do.
Absolutely not. It is simply what tracking the skill, not the age, could actually look like in three very different rooms. At break, ask whoever's next to the kettle. Does our school assume phonics stops mattering after key stage one, or is there an actual plan for a year nine who's still stuck on decoding? Honestly, Most secondary staff rooms I've been in would say the first one, you know, without really thinking about it. They just assume it stops mattering. If an inspector asked your secondary English department how you catch a pupil who still can't decode multi -syllabic words, could you point to something or would we assume that's sorted by now be the honest answer?
And that is the actual test, isn't it? The test is not whether every single year nine people needs phonics. The true test is whether the ones who do need it actually get spotted at all. I'll believe phonics is a primary thing the day someone shows me a secondary pupil who stopped needing to decode words just because they turned 11. Here's what to try today. The next time a pupil freezes on a multi -syllabic word in any subject, don't just supply it for them. Ask them to break it into chunks first and see what they can do with it.
It is the exact same finding turned into a practical action. Check the skill before assuming the edge has already solved it. Four things off the drive. One. Plus five months, high security, four out of five padlocks, the strongest evidence base this show's carried. Two, it works the same for older strugglers as younger ones on a thinner but real evidence base. Say that caveat, don't drop it. Exactly. Three, it's decoding, not comprehension. Pair it with the right support. Don't expect it to do both jobs. Right. Four, disadvantaged pupils show similar or slightly greater benefit.
Not less. Before we close, just think about what it actually does for a pupil's confidence when they realize they have a system to unlock words, rather than just guessing or waiting for the teacher to rescue them. Everything's linked in the description, the toolkit page, the padlock breakdown, the lot. Read them. We're the trailer, not the film. Both voices on this show are synthesized. The judgment isn't. Safe trip in. See you at the gates.
