The Tech

To create the best learning experience there is, and give every student access to the latest technology to support their learning.

Good tutoring has always worked: someone notices the mistake, explains it, and checks later that it has gone. Not every family can pay for that, or find it. Kudos is built to do those things for every child who practises, and the rest of this page shows how. Four things guide the way we work:

Digital first

Every answer your child gives, in daily practice, Bootcamp and mock papers, adds to one picture of how they learn. Our algorithm uses it to choose what they are asked next, so their practice is their own, and your parent portal shows you their mistakes in detail.

Fair

We don’t lock you into a contract or ask for card details up front. We would rather show you the value first: a 7-day free trial, after which you decide whether to stay. Our explainer videos are free to watch on every topic page in Resources and on our YouTube channel, with no subscription.

Responsible

We are upfront about the data we collect, and we follow the ICO’s Age Appropriate Design Code. Your family’s data is held in Ireland, in the EU, and encrypted both in transit (TLS) and at rest (AES-256). Your child’s answers are never sold, and never sent to advertisers or AI companies. You can delete your account, and everything your child has practised, yourself at any time from Settings. Where we study answers across many children, they are pseudonymised first.

Transparent

We share as much as we can about how Kudos works without giving away what makes it work. We keep researching what helps children learn, improve Kudos quickly with what we find, and write it up here so you can follow along.

We built an algorithm that optimises for one thing: a child stops making the same mistake, for good.

Not the next answer, not minutes in the app, not streaks. A mistake only counts as fixed when it stays fixed, so we keep checking long after it was made. Along the way, four rules hold:

Within reach

Questions stretch the child without swamping them.

A floor under frustration

After a hard patch, the next session opens with a question the child can do.

Nothing left behind

Every topic comes round, not only the ones that look most urgent.

Honest

Every question is chosen for a reason, and we say plainly what is running and what is still planned.

Every practice answer, daily or in Bootcamp, feeds the same loop, and a wrong answer goes through these steps on the way round.

1. 1

   Named

   Every question is written to catch a particular mistake, and in Bootcamp and mock papers each wrong option catches its own. When a child gets one wrong, Kudos records the mistake by name, and the explanation they see is about that mistake, not only the question.

2. 2

   Explained

   For the most common mistakes, the child also gets a short tip under the working on how to beat the habit. We try more than one way of explaining each, and show more of the ones after which children stop making it.

3. 3

   Tested again

   Over the following days and weeks, the mistake comes back as a fresh question, to check it has stuck rather than been remembered for a moment.

4. 4

   Counted

   Once the child gets it right after a gap, it counts as fixed, and the parent’s page lists the mistakes fixed each month by name. We keep checking afterwards, so we know which ones stay fixed.

Each daily session is built for the child in front of it, from their very first answer. Kudos keeps a running picture of what each child can do, topic by topic, and of how hard each question really is, and every answer sharpens both.

A session starts with any re-tests that are due. The rest mixes the child’s open mistakes, their weakest areas at questions they can reach, and topics they have not seen for a while, so nothing slips. A question chosen because of a mistake tells the child so, with “One more go at” and the mistake’s name.

Bootcamp’s weekly set works the same way inside the course. It only draws on topics the course has reached, is centred on this week’s, and brings the child’s re-tests and open mistakes into it, so a child who only does Bootcamp gets them too.

Before a change to how sessions are chosen reaches a child, it is run for a month against a simulation, beside random practice. How we chose the question algorithm says what that found.

The longer questions, written up with their method and their limits. Where we use our own data, it is pseudonymised first.

  Why we moved to twenty questions a day

  Daily practice is now twenty questions, with ten for a busy day, and the weekly set is fifty, or twenty if your child prefers. What we saw when we tried longer sessions.

  How we chose the question algorithm

  We tried four versions of the way Kudos picks questions in a simulation, side by side with random practice. What each one got right and wrong, and why the app uses the one it does.

  Evaluating our question algorithm

  Before a change reaches your child, we test it in a simulation: a month of practice in minutes, run with Kudos and with random questions, so the two can be compared fairly.
