JFS has announced it will open a bulge class for September 2020 to help meet the demand for places at state-aided secondary Jewish schools in North-West London.
The oversubscribed school, which normally allocates 300 places for year-seven entry each year, has offered an additional 30 for this autumn.
According to one parent, the school was facing 37 appeals for admissions in autumn.
In a statement, governors said, "At a time when we are seeing a very significant surge in applications for Jewish secondary schools, we take seriously our responsibility to do all we can to ensure that any Jewish child who wants an education in a Jewish secondary school will if at all possible, be accommodated."
