the jewish community secondary school (jcoss) is a state-funded jewish secondary school in new barnet, london. established in 2010, it is the first cross-denominational secondary school in the uk. it was established after a mother observed that while her son had gone to jfs, a nearby jewish school, many of his friends had not been able to attend because of oversubscription and halachic requirements, and initiated in 2001 the ultimately successful proposal for a new faith school. construction of the school began in april 2009.
