28 April 2026Curriculum Conversations (Episode 2): Cassie Buchanan on leading curriculum change

Emma McCrea
Head of Curriculum Design
Why does the curriculum review matter, and what could it unlock for pupils and teachers over the next decade?
Hear directly from a member of the Curriculum and Assessment review panel in my conversation with Cassie Buchanan, who was part of the review panel and is also CEO of Charter Schools Education Trust.
In our conversation, she shares early reflections from the review process, alongside practical perspectives on what meaningful change could look like in schools.
Watch our 20-minute conversation to learn:
- What the clearest messages from the review are so far, and what young people may need more of in the future.
- How leaders can approach curriculum change across multiple schools while respecting local context.
- What subject leaders and staff will need most from senior leadership as reform begins to take shape.
Hello, I'm Emma McCrae
and I'm head of curriculum design at Oak.
Today, I'm joined by the brilliant Cassie Buchanan,
who is CEO of Charter Schools Education Trust
and was a member
of the Curriculum and Assessment Review Panel.
In our discussion today,
we'll cover what the clearest messages from the review
are so far.
What young people may need more of and want in the future.
How leaders can approach curriculum change
across multiple schools,
while still respecting local context,
and also what subject leaders need to know and do
ahead of the curriculum reform.
Thank you for joining me, Cassie. Hello.
Hi, Emma. This is very lovely, isn't it?
It is a bit fab.
Quite different from the classroom.
Yes, definitely. Definitely.
As a member of the Curriculum and Assessment Review Panel,
what was the clearest message
that you heard about what young people need more of?
I mean, there were lots of messages, over 7,000 responses
to the call for evidence,
but the first thing we heard very strongly from teachers
was that we have a really great curriculum already.
So the jumping off point wasn't to dismantle
the good stuff that was there.
Teachers really value subject disciplines
and having a really knowledge-rich curriculum.
So that's a great place to start.
That's a really good foundation.
The second thing we heard,
and it came through in our call for evidence,
but also in the data that we're able to see,
is whilst that really strong curriculum is working well
for most children, young people,
it isn't working well for everybody.
So the disadvantage gap persists,
children with special needs don't progress as well.
So that's an equity question
that if we have this really strong foundation,
it needs to be a foundation upon which
everybody can stand and succeed.
And then when we heard from the young people,
they talked a lot about the future and having knowledge
and skills to equip them for the future that perhaps isn't
explicitly there in the curriculum as it was.
So that's about skills such as media literacy,
critical thinking, climate education, sustainability,
financial education, that came through really strongly,
and oracy.
So that was another theme,
and there's a recommendation about that.
So young people really wanting the opportunity
to learn how to speak with greater confidence,
to be able to master all of this knowledge
and then be able to talk about it.
And the written word is still important,
but obviously speaking is as well.
So it was a balanced message
through that funnel of all of those many different
and diverse voices.
There were some pretty common themes.
So what's lovely particularly to hear
is that when you look at the curriculum
and assessment review report,
you see the voices of the young people
in terms of some of these recommendations about the themes
that hopefully will provide some horizontal coherence
across subjects, but also speak to their needs
in terms of what they want for their future.
So that's really exciting.
Let's talk a little bit about
some of the more difficult choices
that you might have faced within the panel,
because curriculum reform always involves
some sort of difficult choices and key tensions.
Can you tell us a bit about what you wrestled with?
Sure, I think the first one,
probably the one that most teachers and leaders
will be familiar with, is this tension between
breadth and depth.
And if we had all the time in the world
and the 24-hour clock was no more,
then you would want to and would consider it your gift
to do everything, to teach everything,
for that kind of knowledge to span as wide as the horizon.
But in reality, we are constrained by how long children,
young people are in school.
So that tension between how much in terms of volume,
so content volume versus depth of understanding
was there and will always be there.
And what we were really aware of because teachers told us
is that that ambition in terms of volume of content,
which we would want and we want sometimes got in the way
or gets in the way of ambition in terms of understanding.
And so one of the key recommendations or themes
that threads through the review is this idea of mastery,
which you're a mathematician,
so you'll be very familiar with,
but perhaps is new to other subjects.
So giving every subject enough space and air
so that people aren't racing to cover the curriculum,
that idea of covering the curriculum is replaced by depth
of understanding and feeling like children,
young people have really learnt something.
So that's the first one.
Sounds great. I mean, it's hard to achieve.
So that's the first one.
But the second one I would say is this tension between
a national entitlement.
So wherever you live in the country,
whether you're in Cornwall or London where we are today
or up in Yorkshire that you, as a young person,
that you have an entitlement that is the same.
And that speaks to that equity question
that we should make sure
that there's a sort of minimum entitlement
that is still super ambitious
that everybody gets versus local,
and I can never quite say this word, but specificity.
There you go.
I struggle with it too. There you go.
Specificity. I'll say it faster now.
It's a word. It's not us.
And giving enough time in the school day for teachers
and to teach the stuff that is really important
for their local context.
So that's the school curriculum.
And in addition to that,
there being enough time in the school day
and time is the thing that's coming through here
for extracurricular stuff.
So not the formal curriculum,
but visits, clubs, those things that we know
make a really special school experience.
So that's another tension.
And one of the things that came back in the call
for evidence is this tension around volume.
But then when you ask, well, what should we take away then?
That's a harder question to answer.
The third one, and this one obviously got
quite a lot of headlines,
is around the EBacc and accountability.
The EBacc does some really good work.
So it increased the take up of some academic subjects
and that's a really good thing.
But it came at the cost of reducing take up
and constraining choice,
particularly around creative subjects.
So that's a challenging one
because you want to sort of maintain the great work
that's already happened.
So that's why that recommendation there
is to remove the EBAC, but to retain that academic core
and hopefully that resolves some of that.
And then the final one,
which is always a tension in education,
we all want to move it a million miles an hour,
but we can't do everything at once,
is that challenge around how do you deliver
and put in place all these recommendations,
but recognize that it's teachers and people in schools
who are going to have to implement this stuff, right?
So managing stability and making sure that the things
that we've chosen were the things
that were going to make the biggest difference
versus lots and lots of change.
And that's where Becky Francis' evolution,
not revolution comes into play
because every choice is a change
and each one of those changes is potentially disruptive.
Trying to keep the change to the things
that are going to really make the difference.
And when I say really make the difference,
that's a child-centered difference.
So who are we making the difference for?
Those young people that we spoke about
at the top of the conversation.
Yeah, absolutely.
What's really interesting about what you say
is you can feel as a MAT leader
or a school leader or a subject lead
that those tensions play out in the school curriculum
as well as obviously you've been wrestling with them
at the national level as well.
As a trust CEO, how do you approach curriculum change
across multiple schools while still respecting
each school's context?
Oh yeah, that's a tricky one.
I mean, I would say that I am a trust CEO obviously,
but I'm also a teacher first, right?
Yeah.
And a head teacher second and then a Trust CEO third.
So I would say that I've been really careful about this.
So we don't at the Trust that I lead
have one singular curriculum.
We do have aligned curriculum principles.
And so we thought really carefully
about what makes a good curriculum.
And at the heart of that is coherence, so vertical,
horizontal coherence, being knowledge-rich,
making sure that our curriculums reflect our communities.
So there being curriculums that both include,
that children can see themselves in,
and also give children an opportunity
to see beyond their own community.
So that's really all of those sort of principles,
and there are more, are really important to us,
but we don't have one standardized curriculum.
That's not to say that there aren't bits of our curriculum
that are the same actually.
So we have a shared reading fluency curriculum
that is just the good stuff has moved around.
We've got schools that use Oak
for different parts of their curriculum because,
and I guess that leads me into the next bit,
that the subject expertise,
that's where curriculum change needs to sit.
And so my job is, as a CEO, is definitely not to dictate
what's in the curriculum or how it should change,
but it is to make the time, the space, the conditions
for subject experts to have those conversations.
And where, for example, and this can happen in primary,
especially little primaries,
where perhaps we don't have a subject expert
in every subject to connect them
to where that subject expertise might sit.
That goes back to that time question.
Yeah, absolutely.
There are only so much time in a teacher's day.
So some of our schools, some of our subject leaders
then use the subject expertise
that perhaps sits outside of their school
that they can bring in and adapt.
So the subject expertise I think is subject leaders,
teachers is where that curriculum change needs to happen.
What I want to just drill in on a little bit quickly,
if I may, you said that your trust has a level of autonomy
where schools don't necessarily have to have
the same curriculum.
And I wondered if you could share your rationale for that,
because of course there are MATs
where they kind of pool expertise.
There's pros and cons, of course of having set curricula
across all your schools versus what you have
where you've got shared principles
that underpin those curricula,
but actually the curriculum themselves are different.
So we've really thought about the things that we align,
the things that we centralize,
the things that we standardize as a trust,
as a group of schools.
And curriculum doesn't sit in that standardization box.
Why? Because it's complex.
School curriculum should reflect and support
the community of children that it serves,
all of our schools, although they're all in
three-kilometer circumference with each other.
All of those communities are all hyper local
and they all have different needs.
They have teachers and leaders
who have particular skills and talents.
So we have that national curriculum core
that runs underneath.
And then the school curriculum,
what makes that school unique?
I think should be unique to each school.
And so it sits for us.
And school curriculum,
I think is something that is a complex decision
and things that are complex are best decided upon
by the people closest to those children, young people
for whom it will impact.
So that's our rationale.
If you're going to do that,
you have to have alignment in principles
and those principles need to be really evidence informed.
So being evidence informed is one of them
because that pulls people together
and makes sure that those decisions that subject leaders
are making are decisions that are based on
the very best evidence of what works
both within their school,
but also outside of their school as well.
Yeah, you must end up with these
great kind of pools of expertise within your schools
and probably more so in some subjects than others,
different curriculum.
How do you facilitate learning from each other in terms of,
oh, actually this school in English
has got this great unit on so-and-so.
How do you move the good stuff around?
Right. Exactly, exactly.
And maybe the bad stuff out the window,
but I'm sure there isn't any of that.
No. I mean, schools aren't islands.
Our schools definitely are not islands.
One of the points for me being in a trust
is that you move the good stuff around.
So we have subject networks, so subject teachers,
secondary leaders at primary,
people who are just a bit interested,
come together on a really regular basis
to share curriculums.
So whilst I say it's a school decision,
what you will see when you go,
well, you've seen when you go from one school
to another school in our trust
is you'll see the same curriculum
or you'll see bits of the same curriculum
and you think, "Oh, where's that come from?"
So allowing and creating the conditions for teachers
to work together, subject leaders to work together,
and to be able to evaluate and think, "Why is this good?
And why is this one better than this one?"
And do that together,
that is a sort of horizontal peer-to-peer choice,
means that you do move the good stuff around,
but that you give teachers and leaders the agency.
So you spoke at the beginning about autonomy.
I would challenge you to think about, from my perspective,
we talk about agency.
We want teachers in schools to make the best decisions
based on the best evidence.
I don't want them to work in complete isolation.
It's balancing the two, isn't it?
You want to move the good stuff around.
When you see something really good, you want to kind of say,
"Why isn't everyone doing this?"
But at the moment at which I do that,
agency goes and we want agency too.
Yeah, and you want them to have agency
in terms of this sharing?
Yes.
And actually you probably end up with a shared curricular
to a certain extent whereby-
It seems pretty shared, yeah.
It's different in some parts, but actually the good stuff
has been shared around which is what you want.
The good stuff has been shared. Yeah.
Perfect, let's talk a little bit about workload
because clearly with curriculum reform
comes quite a high level of workload,
also opportunities for change, of course.
What can schools do and leaders to minimize the impact
that curriculum reform has on workload
whilst seizing this opportunity for change?
Okay. So I would say the first thing is time.
So give back to that old time word again,
give teachers, subject leaders time.
And that isn't just time for writing.
It's time for thinking, it's time for speaking.
It's time for coming together to discuss
both the curriculum review itself.
So what do people think? Have people had time to read it
and talk about it?
And then once the national curriculum is published,
then it's time to think about
what they need to adapt in their own school
or trust curriculum.
So that first one is time.
I think we forget the second one is clarity, really.
Clarity about decision making.
There's nothing worse than a teacher,
and we've all been there, spending a long time
making something very thoughtful and beautiful
only to discover it wasn't within our gift.
So clarity around decision making.
So what is going to be, and we'll have to wait to see.
So what is going to be at a national level
just decided for us?
What then are school trusts or groups of schools
going to decide or trust or group decisions?
And then finally, what is going to be within the gift
of subject leaders in each individual school
to then decide upon?
And that will be a senior leadership bit of work
that will need to happen in advance of letting teachers
loose on writing school curriculums.
And then finally,
there's something about culture, isn't there?
And that is around developing or when you have it,
really maintaining and nurturing a professional culture
that values teachers' professional expertise,
their learning and their thinking and giving time for that.
So that will be different in every context,
but culture is pretty key to every change.
Yeah, absolutely.
And this goes back to your point actually
about there will be some instances where perhaps
we talked earlier about a small primary school
where maybe that expertise isn't there.
So actually there's some careful thought to be done about
who is best placed to do this work
and how can we minimize workload through
using other sources or sharing expertise locally
or using Oak, for example,
that are also quite critical, I think.
Okay. Thank you so much, Cassie.
Oh my pleasure.
It's an absolute joy to talk to you.
Thank you for coming and spending your time
to geek out about curriculum.
Always.
Thank you.
Thanks for watching.
