I got it wrong. For a long time, I thought intervention would close the gap.
It didn’t.
When I first took on my role, I believed something that, on the surface, seemed logical:
If we identify disadvantaged students early and provide targeted support, the gap will close.
So I focused on:
– Intervention
– Revision sessions
– Extra support at key points
And while some of this helped, it didn’t fundamentally change outcomes.
Because I was making a mistake.

Mistake 1: Treating intervention as the solution
Like many teachers, I leaned heavily on:
– After-school sessions
– Small group work
– Additional revision
My research had already suggested that:
Targeted support and one-to-one intervention are seen as highly effective strategies.
But it also highlighted a crucial issue:
The biggest barriers to delivering these effectively are time and class size.
In practice, this meant:
– Not all students attended
– Support was inconsistent
– Impact was limited
I eventually realised:
Intervention can support success, but it cannot replace the need for strong classroom teaching.
Mistake 2: Acting too late
Initially, most of my focus was on KS4.
This is where the pressure is highest:
– Exams are approaching
– Data matters most
– Accountability is immediate
But by the time students reached Year 10 or 11:
– Gaps in literacy were already embedded
– Writing skills were underdeveloped
– Confidence was low
At this stage, improvement was possible—but limited.
I was trying to fix in two years what hadn’t been built in five.
Mistake 3: Underestimating literacy
Early on, I assumed that if students understood the content, they would be able to demonstrate it.
But this wasn’t the case.
Students could:
– Explain ideas verbally
– Engage in discussion
– Show understanding in class
Yet when it came to writing:
– Responses were brief
– Structure was weak
– Vocabulary was limited
This reflected what research has long shown:
Disadvantaged students often face a gap in access to academic language, which affects their ability to succeed.
I had underestimated how central literacy is to success in History.
Mistake 4: Focusing on engagement over outcomes
Like many teachers, I wanted lessons to be:
– Engaging
– Interesting
– Memorable
And while this is important, I began to realise:
Engagement alone does not guarantee progress.
Students could enjoy lessons, participate actively, and still:
– Struggle with extended writing
– Underperform in assessments
The missing link was not engagement, it was deliberate practice of the skills required for success.
Mistake 5: Lack of consistency
Another issue was inconsistency across:
– Classes
– Teachers
– Year groups
Different approaches to:
– Writing
– Assessment
– Expectations
Meant that students:
– Had to constantly adapt
– Did not build secure routines
– Lacked clarity on what success looked like
Over time, this created confusion and slowed progress.

What I changed
These mistakes led to a shift in approach.
Instead of:
– Relying on intervention
– Focusing on KS4
– Prioritising engagement alone
I moved toward:
– Embedding extended writing in every lesson
– Aligning curriculum and assessment from Year 7
– Explicitly teaching vocabulary and structure
– Creating consistent expectations across the department
– Using intervention to support, not replace, classroom practice
What I learned
The most important lesson was this:
Closing the attainment gap is not about doing more, it’s about doing the right things, consistently, over time.
Small changes, repeated every lesson, had more impact than:
– One-off interventions
– Short-term initiatives
– Reactive strategies
The bigger shift
Perhaps the biggest change was in mindset.
I stopped asking:
“What can we add to support disadvantaged students?”
And started asking:
“How can we improve what every student experiences, every lesson?”
Because disadvantaged students do not need something different.
They need:
– Access to the same high-quality teaching
– Clear expectations
– Structured support
Delivered consistently.

Final reflection
Looking back, my early approach wasn’t wrong, it was just incomplete.
Intervention matters. Engagement matters. Support matters.
But without:
– strong curriculum design
– a focus on literacy
– consistent classroom practice
They are not enough.
The gap is not closed through isolated actions, but through sustained, deliberate practice over time.
If we are serious about closing the gap, we need to reflect not just on what works, but on what we’ve been getting wrong.
