Part one · prep, handled

Walk in prepared. Skip the evening of prep.

PrepBox reads the student's last written work and hands you a working brief — where to start, what to watch for, what's queued next. The practice material is already built and mapped to the exact skill. You review for five minutes and teach.

One click, everything readyWarm-up, practice, and your session notes — built from your student's own math map.
Practice already madeAssign it in one tap — it comes back marked.
Quality up, not just time downMaterial targets the precise prerequisite — not “review Chapter 4.”
Session ready · review, then assign one click. that's the prep.

The real Learning Plan button from the PrepBox tutor dashboard — one click prepares the whole session.

Still part one · ready to assign

Worksheets for the exact topic — not “Chapter 4.”

Pick the exact skill your student is stuck on — from 5,000+ topics — and the worksheet is ready. Assign it in one tap, with your name on it.

The workspace under all three

A surface built for math — where you watch the pen think.

Zoom shows you a face. PrepBox shows you the working — the call, the board, and the marking in one surface. You talk, your student writes, and you see every stroke as it lands.

The video call is built inNo Zoom-plus-whiteboard juggling — voice, video, and the shared board are one screen.
Live handwriting, not screen-share squintingYour student writes on an iPad or in the browser; you watch the pen think in real time.
Marking handled, evidence keptWork comes back checked in seconds — saved, replayable, and mapped to 5,000+ topics.

Part two · the training track

A room where tutors show their work.

Tutor groups online are full of advice about rates and no-shows. There is nowhere tutors actually practice the craft — the explanation itself. We're building that room, and it runs on one artifact: your strokes and voice, recorded together as a solve card.

Weekly Show Your Solve One problem a student got wrong this week — and how you re-taught it. Five minutes, whiteboard and voice. Deliberate practice, with feedback.
Monthly The Hard One A genuinely hard student problem from the platform. Competing solves, different routes, one featured explanation. Exam season supplies the material for free.
Always Polished & featured Featured solves are edited with you — teaching feedback from curriculum educators, then published under your name. The training and the exposure are the same act.
25 founding seats. Hand-picked. Certification included.

The first cohort sets the tone: serious tutors who want to sharpen their teaching, shape the rituals, and certify free before the doors open. If that's you, say hello — a sentence about who you teach is plenty.

Ask for a founding seat

Part two · the milestone

A credential you earn with your pen and your voice.

Anyone can pass a quiz. PrepBox certification works the way real teaching interviews do: you demonstrate, on the whiteboard, out loud. Problems are drawn fresh from the topic graph for every candidate, and the work is assessed by educators against a published rubric — the same rubric the training track drills.

R1
The solve round

A randomized set of problems across your grade band, drawn from 5,000+ topics. You solve on the PrepBox whiteboard, explaining aloud as you write — strokes and voice recorded together.

R2
The teach round

Real anonymized student work — wrong answers included. Diagnose the misconception, then re-teach it the way you would in a live session. This is the round that separates solvers from teachers.

G4–6G7–8G9–10G11–12

Certification feeds part three: it goes on every parent report, it's announced to your families, and it ranks you first in the upcoming Tutor Atlas.

Part three · we promote you

Happy parents don't refer on their own.
So we make the ask for you.

It's awkward to promote yourself and ask families for referrals. So PrepBox does it for you — professionally, and only when your student's progress backs it up.

Why our word is worth something

We never take a cut. That's what keeps our promotion honest.

Marketplaces promote whoever keeps paying the toll — 25–33% of every lesson, for as long as you teach that student. PrepBox charges a flat fee. When we tell a parent your teaching moved a student, it's because the marked work says so — we have nothing to earn by saying it.

And the toll you're not paying stays in your pocket:

Why “your students stay yours” matters

When the marketplace TakeLessons shut down in November 2024, tutors who had built their whole client base inside it lost it overnight. On PrepBox your roster, parent contacts, and every session record are yours — exportable at any time, no questions.

Later · where the promotion leads

The Tutor Atlas — where parents will find certified tutors.

The Atlas opens when the first cohort certifies. Certified tutors rank first, ranking inputs are published, and the connection is direct — parent to tutor, no toll booth in between.
