The school, which was graded as inadequate a year ago, received a follow-up inspection last month.
Wiznitz’s leaders were clear that “making pupils aware of sexual orientation and gender reassignment in year seven goes against the school’s Orthodox Jewish ethos,” Ofsted said.
The inspectorate insisted, “Without simple changes, the school will continue to fail to meet these requirements.”
Ofsted acknowledged that the school had taken steps to improve its secular education but further progress was necessary. English literacy remained “poor”, it said.
