Vishnitz Girls School, a religious private Jewish school located in the east London borough of Hackney, risks closure, The Telegraph reported.

The school teaches girls from age 3 to 8, and pupils speak Yiddish as their primary language with a 50/50 split between Jewish and secular studies.

Vishnitz Girls School is one of seven faith schools that failed an Ofsted inspection in the space of a few weeks.

According to Schools Week, Vishnitz was not the only religious private school to fall short of the Ofsted, the Office of Standards in Education, Children’s Services and Skills, checklist standards. Three schools have seen their Ofsted grades drop due to “lack of progress for pupils.” Bnos Zion of Bobov, also in Hackney, failed the Ofsted inspection because the school made “no reference to protected characteristics for sexual orientation and gender reassignment.

Although faith schools in the UK are not required to follow the national curriculum laid out for state schools, it is mandatory for them to follow standards for sex education issued by both the Department for Education and Ofsted.

Inspectors visiting Vishnitz Girls School last month said the Orthodox school does not give pupils “a full understanding of fundamental British values”, The Telegraph wrote.

Pupils were not taught about LGBT issues such as “sexual orientation”, which are in breach of equality laws.

According to the Ofsted report on the school, teaching there contravenes the law as set out in the Equality Act 2010, which makes it mandatory for British schools to educate on a range of “protracted characteristics,” including age, disability, race, sex and sexual orientation. “This restricts pupils’ spiritual, moral, social and cultural development and does not promote equality of opportunity in ways that take account of differing lifestyles,” inspectors reported. The report said that pupils “are not taught explicitly about issues such as sexual orientation”.

The report went on to say that the school leaders “recognize the requirements to teach about the protected characteristics as set out in the Equality Act 2000.

However, they acknowledge that they do not teach pupils about all the protected characteristics, particularly those relating to gender reassignment and sexual orientation.

“This means that pupils have a limited understanding of the different lifestyles and partnerships that individuals may choose in present-day society.”

Vishnitz school has 212 pupils and the annual tuition fee is £5,200 (around 5,900 euros).
