Welcome to The John Warner School

At The John Warner School we are proud to be a school that has provided a first-rate education to young people in Hoddesdon since John Warner built a school for children of all classes and religious beliefs in 1841. We have worked tirelessly to build on this rich history to ignite a lifelong passion for learning, to discover and develop potential, allowing all to flourish in an ever-changing world.

That hasn’t, however, come without its challenges – and we are currently making important changes to ensure that we meet the high standards that we set ourselves.

We look forward to welcoming your child to our school community. The information on this page which will support the transition between primary school and secondary school.
