Chasidic boys' primary school in Stamford Hill is still to satisfy inspectors despite a fifth visit in two years.
Ofsted said Beis Aharon had to do more to meet the standards expected of independent schools.
Earlier this year the school lost an appeal to the Care Standards Tribunal against an order from the Department for Education not to admit new pupils until improvements were made.
While the school has adopted a more systematic approach to teaching English and maths, its secular curriculum remained "too narrow", Ofsted said.
After previous criticism of the covering-up of images of women in textbooks, inspectors have now reported books "no longer show signs that pupils are being restricted in their access to images".
But they added that "the range and quality of books on offer does not enable pupils to obtain a broad and rounded view of life in wider British society".
Pupils showed some awareness of British institutions and knew about the role of the Mayor of London. However, "their deeper understanding of the wider community continues to be limited by decisions leaders have made about the scope of the curriculum".
