Pupils at a Chasidic boys’ school in Stamford Hill which has been visited by inspectors six times in three years, struggled to name Prime Minister Theresa May,  according to its latest Ofsted report.

Beis Aharon, which has 333 pupils aged from three to 13, was found to still fall short of the required standards for independent schools.

Inspectors said knowledge of British institutions remained “very superficial”. Its oldest pupils were not being taught science and the early years curriculum did not develop English-language skills.

There were contrasting fortunes for two recently inspected Charedi independent schools in Salford. Mechinoh, a small school with 57 boys from 11 to 16, was rated inadequate, the lowest grade.

The secular curriculum was restricted to English, maths, science and sport, though geography was sometimes included. Secular teaching was effective but progress was slower than in Jewish studies.“Opportunities to help pupils understand the wide range of people and cultures which contribute to modern Britain are limited,” inspectors reported.

Ofsted found improvements at another secondary boys’ school, Beis Hatalmud, which has 81 pupils
