The state-aided Lubavitch Girls Primary in Hackney has retained its status as a good school — though Ofsted said it might not do so in a full inspection.
Good schools receive a visit from Ofsted every four years to check they are maintaining standards.
But inspectors may recommend a fuller inspection which would normally be carried out a year or two after the visit.
Ofsted said after a short inspection in September that “evidence gathered suggests that the inspection grade might not be as high if a graded inspection were carried out now”.
The primary school last received a full inspection nine years ago before it became an academy.
On the plus side, inspectors noted the enthusiastic and motivated pupils who “responded favourably to staff’s high expectations”.
The curriculum was particularly strong in reading and maths but in geography and history pupils “do not cover key knowledge deeply”.
They were found to lack knowledge on how to stay safe online and while leaders had planned opportunities to learn about other faiths and cultures, pupils’ knowledge was “superficial”.
Judith Nemeth, executive head of Lubavitch Multi-Academy Trust, said, “We are delighted our school retained the good rating, which was achieved as a result of excellent teamwork”.
