JCoSS is one of the first schools in the country to implement the government’s new relationships and sex education policy.

The cross-communal secondary school in East Barnet has been recognised by the Department for Education as one of the “early adopters” of the RSE curriculum, which does not come into force nationally until the autumn.

A JCoSS spokesman said it had been redeveloping personal, social and health education over the past couple of years “coincidentally at the same time as the government has started to introduce statutory RSE”.

The programme’s name, Kvutzah, refers to the importance of community-building.

“We have been specifically working to ensure that our RSE curriculum is inclusive of all of our students, reflects our Jewish values and heritage, and adequately prepares our young people for the experiences that they will encounter in their lives,” the spokesman said.

“We are very proud of this pluralist Jewish approach to RSE and have shared our best practice with a number of other schools.

Being an early adopter gives the school access to training and resources ahead of other schools.
