RCTs have value but they are overrated in education. Education is a highly dynamic system. Isolating a single variable feels right but it can be misleading.
Consider a similarly dynamic and interconnected field, cooking. You can isolate a single ingredient and study if it tastes good or bad, but that is mostly irrelevant when cooking a dish. Corn flour tastes terrible on its own but that doesn't mean it's not useful. Salt is perhaps the most important ingredient in all of cooking, but too much of it will make your dish inedible (and eventually kill you)
Even if Explicit Instruction is salt (which it might be! I think it's really important!), that doesn't mean it's all you need.
Sometimes I feel like I'm reading people on twitter who went from "season your food!" (which is good advice) to "let's all eat nothing but salt."

3 weeks for a review in NI #education. Led by TB. Full of assumptions such as behaviour is a problem of pupils, that it is worsening and that solutions lie in identifying “what works” in terms of school‑level interventions. No explicit acknowledgment of structural, relational or systemic contributors ensuring the framing leans toward a particular behavioural paradigm rather than an open exploration. consultations.nidirect.gov.u…
When polemic replaces evidenced debate.
Replying to @HLearningPD
From @tombennett71's foreword: "It is a duty upon us to use the best teaching strategies we can. This is too important to leave to the mixed-methods charlatans and literacy hobbyists."
So comparing PISA England samples 2022 and 2025, tests were conducted Nov-Dec 2022 and then Feb-May 2025. Claims of stable scores surely questionable?

PISA results out today. Look at this for England. Sample of participating pupils = 24% FSM. Compared to 40% who did not participate! Yes, our results look good. But remember, our scores are likely upwards biased by around 10 points!

This is an interesting and informative thread. Especially interesting to see the prior attainment figures! Also the EAL stats.
"Can Michaela be scaled?" was an interesting question in 2016
It's not an interesting question today, because we know the answer, and it's "no."
Whatever the reason for that (see first reply), it seems to be a simple fact that it hasn't been scaled, despite everything being in place for it to be scaled:
It's had *thousands* of visitors. Books, blogs, conferences, national press, a documentary and a headteacher with more air time than any other in the country, and despite all that there are but a handful of schools that have come close to emulating what it's achieved.
That's not to say it hasn't been influential. It's helped many to raise their expectations and it has helped shift the overton window on "acceptable approaches to pedagogy and curriculum" in this country. But that isn't the same as "scaled" or "emulated" in any way.
And it's also hard to disentangle the influences back in those early days. Mossborne, Ark King Solomon and West London Free School all opened before Michaela, and that's not even to mention the influence of the KIPP school in the US. So if a school decides "oh you know what, let's go knowledge rich and do centralised behaviour etc etc" that isn't necessarily because of Michaela, because there are many forces involved.
None of this is to denigrate Michaela's achievements, which are clearly astonishing. It's just to say that if the model hasn't scaled by now, it's unlikely that it ever will.

MG and NG reforms become more successful (in their own minds) the more selective the memories they choose to recall.
Teacher recruitment and retention, Special Needs, Pupil Wellbeing and the widening ‘disadvantage’ performance gap all seem to have been conveniently forgotten.
I wanted to understand how @alphaschool selects their student population. Not easy. I asked. They didn't answer. But founder @mackenzieprice & principal @jliemandt do a lot of interviews. So I analyzed dozens of them and made this list of student requirements. 🧵
Nope: % not achieving 4 mathematics including resits
2023: 39.0% (61.0% passed)
2024: 40.4% (59.6% passed)
2025: 41.8% (58.2% passed)
2026: 42.8% (57.2% passed)

And those receiving Technical and Vocational qualifications?
Congratulations to all young people receiving their GCSE results today and recognition too for the sustained, dedicated work of their teachers and support staff.
Yet another cohort has navigated England’s unusually exam-heavy assessment system. Many students have faced more than 30 hours of high-stakes testing - far more than their peers internationally.
This places too much weight on performance over just a few days, when illness or other circumstances can have a significant impact. End-of-course exams can also prioritise memorisation over the wider skills we know are essential for work and life, including communication, collaboration and problem-solving.
The Millburn Review’s interim report warned that our narrow approach to Key Stage 4 assessment risks disengaging young people rather than preparing them for life beyond school. It’s time to review the one-size-fits-all approach to GCSE resits. For too many young people, it simply isn’t working.
We welcome the new Secretary of State’s acknowledgement of England’s exam burden and urge her to work with the profession to develop a broader approach to assessment that gives every young person the opportunity to demonstrate their strengths.
And we cannot ignore the impact of poverty and regional inequality on educational outcomes. Schools do all they can to tackle disadvantage, but they cannot do it alone. Government must address the pressure and strain experienced by young people in disadvantaged communities - and ensure schools and colleges have the funding they need to support every learner to succeed.
The test of any education system reforms are not evidenced from a single snapshot as @NickGibbUK suggests. It is manifest in the meaningful pathways enabled and enacted in life beyond the snapshots.

Good to see Bruner being referenced.
Interesting study for curriculum design: narrative approaches help with teaching science but not Maths. This shows again that narrative elements like stories are a good scaffold for organising unfamiliar information for novices. If they dont have the prior knowledge to organise ideas and concepts which are so prevalent in science, then narrative approaches would seem to work. sciencedirect.com/science/ar…

On the glories of England’s achievements in PISA, so often quoted, please read this on the DfE’s own website. Don’t be conned by a false narrative. educationhub.blog.gov.uk/202…

This post starts well...but goes downhill.
1. It makes no reference to what came before 2000, no reference to TVEI (1983-1997).
2. It dismisses parity of esteem arguments with poor examples, comparing like with like. The whole idea of 'parity of esteem' is that same level...1/
I've weighed in on the great vocational education debate.
From what we can see of the govt plans, I think they will repeat mistakes of the past.
Also, we need to retire the phrase "parity of esteem". It's not helping.
