A third strictly Orthodox school in two weeks has been reported by inspectors to be resisting requirements to discuss LGBT equality with pupils.

Ofsted carried out an emergency inspection of Mechinoh, a small independent boys’ secondary school in Salford, at the request of the Department for Education.

The school’s leaders, it said, were “resolute” in their decision they would not cover all of the groups protected by equality law. The law includes those of sexual orientation and gender reassignment.

They were also clear, Ofsted said, that “some aspects of the relationships and sex education curriculum will not be taught”.

Mechinoh taught British values such as respect for others and educational trips included a visit to the Slavery Museum.

But inspectors were unable to speak to pupils during their visit and so could not assess their understanding of other faiths and cultures.

Recent Ofsted reports on Ateres Girls’ High School in Gateshead and on Beis Rochel d’Satmar School for Girls in Stamford Hill also noted the omission of LGBT equality.
