Walthamstow Academy defines itself as a school with a Christian ethos rather than an out-and-out faith school.
It's won the Accord Inclusivity Award, which is given out by the Accord Coalition every year.
The Accord Coalition is an organisation which includes religious groups, atheists, teachers and others. It promotes inclusion in education, and campaigns against any form of exclusion in state-funded education on the grounds of religion.
It gives an Inclusivity Award to schools which make a positive impact to the unity of the local community, whose students interact with and respect each other and actively reject prejudice and discrimination.
Rabbi Jonathan Romain, the chair of this year's judging panel, told The Guardian newspaper: "Walthamstow shows how state-funded faith schools and schools with a religious ethos can both be true to themselves and serve the wider community that funds them."
Walthamstow Academy is the first school with a Christian ethos to win the award in the six years it has been running, with the rest being community schools.
According to The Guardian, 36% of pupils at Walthamstow Academy are Christians, with the same percentage being Muslim. 13% have no religion.
Emma Skae, the school Principal, told Premier: "We are delighted to have won this award which is testament to the successful, thriving community that we have built at Walthamstow Academy.
"Inclusivity and respect are fundamental to all of us in our academy, and we are very pleased that what we take for granted in terms of how we behave, has been recognised externally as worthy of celebration".
