Every teacher deserves a great coach. Most get whoever's on their timetable.

    Expert coaching grounded in deep subject knowledge for every teacher in your school, based on their actual lessons, not a scheduled observation. And the evidence, session by session, that it's working.

    “Aristotal is the best I have seen anywhere in the world.”

    I wanted pupils to learn how to calculate the surface area of 3D shapes, building on their prior knowledge of area for 2D shapes.
    That's a clear learning objective. I can see from the transcript that you did indeed build on their prior knowledge — you spent the first part recapping 2D areas before introducing surface area concepts.

    How would you describe your general approach to helping pupils grasp new ideas?
    i like to use real world examples — in this lesson i used physical shapes to make things a bit more real
    That's a good approach. I did notice you brought out the 3D shapes from the box and used them to help pupils visualise the concept — that tactile element can really help make abstract ideas more concrete.

    The Coaching Gap

    You have eighty teachers. You have three people with time to coach.

    Most schools run some version of the same CPD model: INSET days, a coaching pair or two, a middle leader doing informal observations, and perhaps a trust programme that reaches everyone once a term. It works, within limits.

    The limits are time, capacity, and knowledge. A good coach knows their subject. They know the research. They know how to read a teacher's development stage and calibrate their feedback accordingly. They track progress session by session. They follow up on action steps. They notice when a teacher is regressing under end-of-term pressure and adjust.

    No school has enough people who can do all of that, for all of their teachers, consistently, across the year.

    The result is that most teachers get good INSET and uneven coaching — if they get coaching at all. Development becomes dependent on which line manager they happen to have, rather than on what they actually need.

    Aristotal was built for this gap. It extends the coaching relationships your leaders have built — making expert, personalised, evidence-based coaching available to every teacher in your school, every week, at the moment they choose to reflect.

    In a Single Session

    What happens in a coaching conversation.

    A maths teacher records a lesson. She wanted pupils to calculate the surface area of 3D shapes, building on their prior knowledge of area for 2D shapes. She used physical, tactile 3D shapes from a box to make the abstract concrete. Aristotal reads the transcript. The coaching conversation begins.

    The feedback is grounded in the transcript itself — the sequencing from 2D to 3D, the decision to use physical shapes, the stated learning objective. The coaching asks a question that invites the teacher to articulate her own pedagogical theory, rather than delivering a verdict.

    In the same session, if the teacher identifies an ADHD pupil who struggles during late-period lessons, the coaching integrates SEND strategies without a separate referral or specialist support request. The platform sets a specific personal goal — for example, trialling purposeful movement breaks as a practical starting point that aligns with the teacher's structured teaching style.

    That goal is tracked across subsequent sessions. The whole conversation takes fifteen minutes. The teacher chooses when to have it.

    I wanted pupils to learn how to calculate the surface area of 3D shapes, building on their prior knowledge of area for 2D shapes.
    That's a clear learning objective. I can see from the transcript that you did indeed build on their prior knowledge — you spent the first part recapping 2D areas (triangles, parallelograms, circles, trapeziums) before introducing surface area concepts.

    I noticed you brought out the 3D shapes from the box and used them to help pupils visualise the concept. That tactile element can really help make abstract ideas more concrete.

    How would you describe your general approach to teaching mathematical concepts like this?

    The Evidence

    Proof that practice is changing documented for the teacher, aggregated for you.

    Every coaching session generates a structured progress update. For the maths teacher above, the platform set two simultaneous goals: a personal goal (maintaining pupil engagement, with a specific focus on supporting an ADHD pupil through purposeful movement breaks in late-period lessons) and a school goal (developing a broader toolkit of adaptation strategies and scaffolding techniques that benefit all pupils with additional needs).

    Both are tracked across sessions. The progress record shows when the goal was set, what was discussed, and what the teacher tried. Session by session. The record is the teacher's own account, coached out of them and documented.

    Schoolwide Intelligence

    What teaching looks like across your school.

    The Schoolwide Dashboard gives you anonymised, aggregated patterns across all participating teachers. You see which departments are embedding new routines, where the same challenge is appearing independently, and what breakthroughs are emerging without a structured rollout.

    The data does not show individual lesson transcripts to leaders. Teachers control what they record and what they share. What the dashboard shows is aggregate teaching intelligence — the kind of picture that observation schedules can approximate but never fully provide.

    This creates Ofsted-ready documentation with an exportable report showing your schoolwide objectives, why you chose them, how they relate to your wider CPD programme, how they relate to individual teachers and evidence of improvement.

    Audio-Only Recording

    Why teachers are more honest with AI than with an observer.

    Aristotal records audio only. No cameras. No student faces. No hardware procurement.

    Audio-only recording is a deliberate design choice grounded in research: teachers behave differently when they know they are being watched. Video observation captures performance. Audio observation captures practice.

    The coaching conversation is built on what actually happened in the lesson, not on what the teacher chose to demonstrate.

    The coaching is private. What gets surfaced in a session stays in the teacher's progress record, which they control. Leaders see aggregate patterns, not individual conversations.

    “I realized 20 minutes were lost to behaviour management. When I used assertive countdowns, the lesson flowed much more smoothly and I got through more.”
    Secondary teacher, Kent
    Audio only — no cameras
    Audio captures teacher and pupil speech only — no faces, no consent forms, no hardware. Teachers record through the app on any device.
    Teacher-controlled privacy
    Recording is entirely voluntary. Teachers control what they record and what stays private. Leaders see aggregated patterns, never individual transcripts.
    UK GDPR compliant
    Audio data is processed and stored in accordance with UK GDPR. For schools managing teacher wellbeing alongside professional development, the privacy model is why the coaching works.
    Common questions

    What headteachers ask us.

    No. Recording is entirely voluntary. Teachers control what they record and what stays private. The Schoolwide Dashboard shows anonymised, aggregated patterns — not individual session transcripts.

    Teachers consistently report that the private, non-judgmental nature of the coaching is what makes it useful. It is a coaching tool that teachers choose to use — recording is voluntary, privacy is absolute.

    The coaching draws on Rosenshine's Principles of Instruction, the EEF's mechanisms of effective professional development, Lemov's Teach Like a Champion, Sherrington's WalkThrus, and a Teaching Practice Framework developed with John Tomsett.

    Dylan Wiliam reviewed the coaching and called it the best he has seen anywhere in the world. We would suggest that is a reasonable quality benchmark.

    Yes — it is designed to. Aristotal handles the personalised 1:1 coaching conversation that most programmes assume will happen but cannot deliver at scale.

    Your human coaches and leaders focus on modelling, team development, and the relational work where human judgment matters most. Aristotal provides the personalised coaching layer that sits between whole-school INSET and individual performance conversations.

    Yes. Aristotal's anonymised, aggregated schoolwide reporting is designed to support the requirements of the Ofsted toolkit. When setting a schoolwide objective, Aristotal asks senior leaders to describe why they have chosen it, how it links to the school's wider CPD programme and agrees teacher progress metrics it can track.

    The reporting provides evidence of the impact Aristotal is having on delivering the schoolwide CPD objectives. The OUTSTANDING impact rating in our six-school research project refers to Aristotal's own coaching impact assessment, not an Ofsted judgement.
