Two Leyton single-sex schools plan to merge into a single academy, although boys and girls will still be educated separately.
Norlington School for Boys and Connaught School for Girls sent letters to parents explaining the merger will allow them to "share resources" and offer "protection within a changing education landscape".
However, both schools insist they are "committed" to remaining single sex.
Connaught headteacher Avani Higgins wrote: "Recent events, such as the pandemic, mean we have learnt that we can’t stand still and must always be looking ahead.
"A key element of our success is the positive working relationship that exists with local schools and the local authority.
"Following a review by the Exceptional Education Trust [which runs Norlington School]… a proposal has been tabled to formalise a partnership between the trusts that is able to oversee both schools.
"The educational landscape is changing rapidly. Both schools recognise that we must take action to preserve our individual character and ethos, which we are very proud of and know means a lot to the local community."
Both schools have been academies for at least six years but have separate governance arrangements.
In their letters to parents, both headteachers said the schools will keep their own identity, have their own governing bodies and share staff training.
They emphasise that there will be no staff restructures and that both schools will be equal partners in the merged trust.
The schools and the local community are invited to share their views on the merger through in a consultation which ends on 1st April.
