There are only 10 state-aided Jewish secondary schools in the country.
But Ofsted has announced its intention to step up unannounced inspections following investigations into alleged Islamist infiltration into state schools in Birmingham earlier this year.
Ofsted stated that it was "not systematically targeting Jewish state-aided faith schools."
Unannounced inspections were carried out, it said, when "there are concerns about rapidly declining standards;safeguarding, including a decline in the standards of pupils’ behaviour and the ability of staff to maintain discipline;standards of leadership or governance;or the breadth and balance of the curriculum (including where the statutory requirement to publish information to parents is not met)."
