One of the biggest mistakes I think schools can make is confusing participation with progress.
A student answers questions.
Contributes verbally.
Appears engaged.
Completes tasks.
Behaves well.
And as teachers, it is very easy to leave the lesson feeling: “They understood that.”
But increasingly, I think many disadvantaged students become trapped within what I would describe as the illusion of progress.
Because surface-level participation can sometimes mask much deeper issues around literacy, curriculum access, and long-term understanding.
And over time, those hidden gaps often become the reason many students plateau at Grade 3 or 4 despite appearing engaged for years.
The problem schools often cannot see
The Education Endowment Foundation (EEF) has consistently identified literacy and low reading levels as among the biggest barriers affecting disadvantaged pupils nationally.

At the same time, research continues to show that the disadvantage gap remains stubbornly wide, with disadvantaged students nationally still significantly behind their peers by the end of secondary school.

But one of the most difficult aspects of this problem is that the barriers are not always immediately visible inside classrooms.
Because many disadvantaged students are often highly capable verbally.
They can:
- contribute in discussion
- explain ideas orally
- engage socially
- appear attentive and compliant
And because of this, teachers can understandably assume understanding is secure.
But then the written work arrives.
And suddenly:
- answers remain underdeveloped
- vocabulary is limited
- structure breaks down
- analysis remains superficial
- extended writing becomes difficult to sustain
This is where the illusion begins.
Verbal fluency is not always academic fluency
One of the most important things I’ve learned through both classroom experience and my MA research is that verbal participation and deep academic understanding are not always the same thing.
Students can often understand concepts conversationally without yet being able to express them academically.
This becomes particularly significant in subjects like History.
History is fundamentally a language-heavy subject built around:
- disciplinary vocabulary
- extended analytical writing
- evaluation
- causation
- argument
- interpretation
And increasingly, research around disciplinary literacy highlights that success in subjects like History depends not simply on knowing content, but on being able to communicate understanding through specialised academic language.

That distinction matters enormously.
Because many students plateau not because they lack intelligence or effort, but because they cannot yet consistently translate understanding into the language the subject demands.
Why some students plateau at Grade 3/4
I increasingly think the Grade 3/4 plateau is one of the clearest examples of this issue.
These students often:
- know more than they can express
- partially understand concepts
- engage reasonably well in lessons
- complete work
- revise content
But their understanding often remains:
- descriptive rather than analytical
- surface-level rather than deep
- dependent rather than independent
And when GCSE exams demand:
- sustained argument
- precise vocabulary
- conceptual explanation
- analytical writing under pressure
the gaps become exposed very quickly.
This is particularly important because many of these students appear to be “coping” throughout KS3.
Behaviour may not be a concern.
Engagement may appear secure.
Teachers may feel progress is being made.
But without deeper literacy development and disciplinary writing practice, students often hit a ceiling later on.
And by KS4, those gaps can feel extremely difficult to close quickly.
The hidden role of curriculum access
One of the biggest shifts in my own thinking came when I stopped viewing literacy as separate from curriculum access.
Because students who cannot fully access:
- vocabulary
- explanations
- modelling
- academic writing
- disciplinary thinking
are not fully accessing the curriculum itself.
This is why I increasingly think schools sometimes overestimate progress based on:
- task completion
- verbal participation
- low-stakes recall
- lesson engagement
without always examining whether students can independently:
- think deeply
- write analytically
- sustain reasoning
- apply knowledge flexibly
The issue is not whether students are participating.
The issue is whether students are developing genuine academic independence.
What changed our approach
In our own department, one of the biggest changes came from recognising that literacy could not sit on the edge of curriculum teaching.
Instead, it became central to it.
We increasingly embedded:
- extended writing into every lesson
- explicit modelling
- vocabulary instruction
- scaffolding
- guided practice
- retrieval practice
- consistent writing structures across year groups
Importantly, we also became much more deliberate about teaching students:
- how to think historically
- how to structure arguments
- how to move from description to analysis
- how to interpret exam questions
rather than assuming these things would naturally develop over time.
The EEF’s guidance on improving literacy in secondary schools is very clear that literacy development must be embedded across the curriculum rather than treated as an isolated intervention.
https://educationendowmentfoundation.org.uk/education-evidence/guidance-reports/literacy-ks3-ks4
And over time, something interesting happened.
Students who had previously appeared “stuck” began improving more steadily because classroom practice itself became more supportive of deeper thinking and writing.
The learning loss schools rarely measure
One thing this also made me think about differently was curriculum access over time.
Because another hidden issue affecting disadvantaged students is partial learning loss that often goes unaccounted for.
A student may technically attend school every day while still regularly missing:
- lesson explanations
- modelling
- independent writing practice
- reading tasks
- retrieval activities
through:
- lateness
- lesson exits
- time-out passes
- internal truancy
- partial attendance
This was one of the reasons I developed a curriculum access and learning-loss tracker within my own context.
The model attempts to visualise:
- actual hours of learning lost
- subject-specific curriculum exposure
- partial absence patterns
- attendance-adjusted curriculum access
What became clear very quickly was that some students appearing “mostly present” were still missing substantial curriculum exposure over time.
And often, these were the exact students appearing engaged superficially while slowly falling further behind academically.
Again, the issue was not always visible immediately.
Which is why the illusion of progress can become so dangerous.
The difference between participation and learning
I increasingly think schools need to become more careful about what we interpret as progress.
Because:
- participation is not always understanding
- engagement is not always deep learning
- completion is not always mastery
And for disadvantaged students particularly, the danger is that surface-level success can sometimes hide widening gaps underneath.
This is why explicit instruction, modelling, disciplinary literacy, and guided practice matter so much. Not because students are incapable. But because academic independence often needs to be taught much more explicitly than schools sometimes assume.
Final reflection
One of the biggest lessons I’ve learned over recent years is that students can look successful long before they are genuinely secure.
And unless schools look carefully at:
- literacy
- writing
- curriculum access
- independent thinking
- depth of understanding
we risk mistaking participation for progress. The problem is that those hidden gaps rarely stay hidden forever. Eventually, they appear in outcomes. And by then, many students have already spent years believing they were progressing securely.
Perhaps one of the most important questions schools can ask is not:
“Are students engaged?”
But:
“Can students independently think, write, and succeed within the language of the subject itself?”
