How to use TheSchoolRun

Testimonials

'My granddaughter is enjoying using TheSchoolRun worksheets and eBooks – they really do make learning fun.'

- Moira, Tring

'Thank you for providing a much-needed service for parents and one which really represented good value for money. I particularly loved your handwriting sections and the ‘Learning Journey’ links that you have created. There are not many services I would pay to subscribe to, and even less I would recommend, but yours is one which I did!'

- Nicola, Aberdeenshire

'I’m not on social media but just wanted to reach out and say I have been recommending you to everyone I know, with kids of course!

Your site has been fantastic. It’s not only teaching my little one things, it’s showing me how things should’ve been done when I was younger. I do wish you were around then, as your content is fantastic and my little boy looks forward to your daily worksheets. Learning definitely made fun.

People are so quick to moan these days, so I wanted to send an email to sing my praises. You’ve helped me become more organised with the schedule of things, but without the pressure I was putting myself under before. We have fun and learn.'

- Katie, Sevenoaks

'I'm finding your site an absolutely fantastic resource alongside the stuff being sent from my son's school. We love being able to keep track of his progress on his Learning Journey checklist!'

- Claire, Kent
