Why a class of ten changes everything (and a class of thirty cannot).

Walk into a primary classroom of thirty. The first ten minutes are register, settling, and re-settling. The teacher poses a question. Three hands shoot up — the same three. A pause. "Anyone else?" Two more, tentatively. The teacher picks one. A correct answer. The lesson moves on.

Twenty-five children just watched. Some understood. Some half-understood. Some didn't follow at all. None of them spoke. None of them were corrected. None of them felt seen.

Now imagine your child is one of the twenty-five.

This is not a failure of any individual teacher. UK primary teachers are some of the most dedicated professionals working anywhere. It is a structural impossibility: thirty children, one adult, fifty minutes. The maths simply doesn't work.

What a child actually needs to learn

Real learning is not delivery — it is response. A child reaches the edge of their understanding, attempts something, gets it slightly wrong, is corrected immediately, and tries again. That feedback loop is the entire game.

In a class of thirty, that loop happens once, maybe twice per child per lesson. In a class of ten, it happens dozens of times.

"Real learning is not delivery — it is response. The feedback loop between a child and a teacher is the entire game."

What ten looks like

In a USTBAS cohort, every child is called on, every lesson, multiple times. There is nowhere to hide and no need to hide. A child who looks puzzled gets a question. A child who answers quickly gets a harder one. A child who is wrong is corrected — clearly, kindly, immediately — and asked to try again.

This is not a lecture. It is a conversation between a teacher and ten children, all of whom are present, awake, and engaged.

The compounding effect

Across a 36-week year, the difference between a child being directly engaged four times per session versus forty times per session compounds into roughly an order of magnitude more practice. Not slightly more. Ten times more.

That is the difference between a child who can do Maths and a child who can't. Between a child who reads with comprehension and one who reads with effort. Between a child who walks into secondary school confident, and one who walks in nervous.

If you have ever wondered why some children seem to "just get it" while others struggle, this is most of the answer. They were taught — not delivered to.

A cohort of ten. By design.

Three places remain
for September 2026.

Each cohort caps at ten students. Once filled, it closes — and the next intake won't open until the following academic year.
