Testimonials

Thank you for all your extraordinary materials that have made working with my Year 6 child such a pleasure.

- Yolanda, London

This is an excellent resource, for anybody looking to understand more about the curriculum that your children are studying and add some extra support at home. Highly recommended by a parent of two children who uses this from Reception to Year 4.

- 5-star review on Trustpilot from Anne-Marie Allman

I loved that the 11+ Programme built up each skill slowly but you knew that everything would be covered by the end.

- Christine

We found TheSchoolRun collateral very useful, timely, fun and relevant for our Y6 child. He went on to attain superb SATs results, with all the hard work definitely making a huge difference.
