For years, “intent, implementation and impact” — the three I’s — was the vocabulary of curriculum conversations in English schools. It shaped how leaders planned, described and defended their curriculum. With the November 2025 framework, that formal structure is no longer the way Ofsted organises its curriculum judgement — but the thinking behind it remains genuinely useful. This article explains what the three I’s mean, where they came from, and how they map onto the way curriculum is evaluated today.
Quick summary
- Intent, implementation and impact were the three pillars of curriculum in Ofsted’s 2019 framework.
- Intent = what you want pupils to learn and why. Implementation = how it’s taught. Impact = what pupils actually learn and achieve.
- Under the November 2025 framework, Ofsted does not mandate the “intent, implementation, impact” structure and does not require any specific curriculum format.
- Curriculum is now evaluated within the “curriculum and teaching” area, with pupils’ learning captured in the separate “achievement” area.
- The three I’s remain a helpful way of thinking, even though they are no longer the formal inspection structure.
What the three I’s meant
The three I’s were introduced with Ofsted’s 2019 education inspection framework to structure how curriculum was designed and evaluated.
Intent
Intent is the why and what of the curriculum: what knowledge and skills a school wants pupils to gain, in what order, and for what purpose. It expresses the school’s ambition — ideally the same ambition for all pupils, including the disadvantaged and those with SEND.
Implementation
Implementation is the how: how the curriculum is taught and delivered day to day. It covers teaching quality, sequencing in practice, and how effectively the intended curriculum reaches pupils in the classroom.
Impact
Impact is the result: what pupils actually know, remember and can do as a consequence. It is the evidence that the curriculum is working — pupils learning and remembering more over time, and achieving well.
Where the three I’s stand under the 2025 framework
Here is the honest, current position. Ofsted’s inspection information for schools states:
“We do not prefer any particular method of planning… We do not expect a specific format for curriculum planning.”
The formal “intent, implementation, impact” structure was a feature of the 2019 framework. Under the framework in use from November 2025, it is no longer the required structure for the curriculum judgement. Instead, curriculum is evaluated within the “curriculum and teaching” evaluation area, and inspectors focus on:
- what children are meant to learn (the substance once called intent),
- how they are learning it (once called implementation), and
- the progress they are making (captured in the separate achievement area, once called impact).
In other words, the ideas behind the three I’s live on — but schools are no longer expected to present their curriculum through that specific framework.
Why the three I’s are still useful thinking
Even without the formal label, the three I’s remain a sound planning discipline. Research found the structure genuinely improved how leaders thought about curriculum. Used as a thinking tool rather than a compliance exercise, it still helps leaders ensure:
- their curriculum has a clear purpose and sequence (intent),
- it is delivered consistently and well (implementation), and
- pupils are genuinely learning and achieving (impact).
The key shift is from documenting the three I’s for inspection to using the underlying logic to build a genuinely strong curriculum.
Intent, implementation, impact at a glance
| Pillar | Question it answers | Where it lives in the 2025 framework |
|---|---|---|
| Intent | What should pupils learn, and why? | Curriculum and teaching |
| Implementation | How is it taught and delivered? | Curriculum and teaching |
| Impact | What do pupils learn and achieve? | Achievement |
What this means for school leaders
- Don’t build “three I’s” documents for inspection. There is no required format, and performative paperwork adds no value.
- Keep the discipline, drop the ritual. Use intent/implementation/impact thinking to design a coherent curriculum, then let real practice speak.
- Be able to explain your curriculum. Whatever your model, leaders should be able to say why it’s designed as it is and how it helps pupils learn — see How Ofsted Evaluates Curriculum Quality.
Frequently asked questions
What do intent, implementation and impact mean?
Intent is what pupils should learn and why; implementation is how it’s taught; impact is what pupils actually learn and achieve.
Does Ofsted still use “intent, implementation and impact”?
Not as a required structure. It was central to the 2019 framework. The November 2025 framework does not mandate it or any specific curriculum format.
Where is curriculum evaluated now?
Within the “curriculum and teaching” evaluation area, with pupils’ learning reflected in the separate “achievement” area.
Should we still plan using the three I’s?
You can, as a thinking tool — the underlying logic is sound. But you should not create documents in that format purely for inspection.
Does Ofsted require a specific curriculum format?
No. Ofsted explicitly does not prefer any particular planning method or format.
Is “impact” the same as exam results?
No. Impact is about what pupils genuinely learn, remember and can do over time — broader than test scores alone. See Building Evidence of Learning Beyond Exam Results.
Conclusion
Intent, implementation and impact defined a decade of curriculum thinking, and the ideas remain valuable: know what you want pupils to learn, deliver it well, and check they genuinely learn it. What has changed is that the three I’s are no longer a required inspection structure. Keep the thinking, drop the ritual — and build a curriculum that works rather than one that merely documents itself.
How AI Buddy supports schools
Whatever curriculum model a school uses, the “impact” question — are pupils genuinely learning and remembering more? — is the hardest to evidence. AI Buddy is designed to support schools in strengthening areas evaluated during Ofsted inspections, providing curriculum-aligned practice that supports consistent implementation and analytics that help leaders see the impact on pupils’ learning and progress. It is not endorsed or certified by Ofsted; it is built to help schools connect curriculum design to demonstrable learning.
