What CleverPath knows, and where it’s from

We don’t pretend our tutor is magic. Every age-appropriate answer is built on published, citable curriculum sources, and every practice question is checked by independent reviewers before a child ever sees it. This page shows exactly what we cover and where it all comes from.

Practice questions

Now in use

Practice questions written by AI, grounded in the curriculum sources above. Every question is then checked by two separate AIs — for accuracy, for the right level for the child’s year group, and for whether it teaches the topic well. Anything they disagree on is held back for a human to look at.

Curriculum coverage

Active practice questions per subject × year group. Empty cells are on the roadmap, not gaps in the curriculum itself.

How every question is checked

Practice questions don’t reach a child until at least two separate AIs have checked them — for accuracy, for the right level for the child’s year, and for whether they teach the topic well. Anything those two AIs disagree on is held back for a human to look at.

Each reviewer is a separate AI. When two reviewers disagree, a human takes a look before the question goes live. We use whichever AI tools are best for the job today; we’ll switch as better ones become available.
