The school will open in September next to Yavneh College in Borehamwood with a two-form reception class, and will have a maximum capacity of 420 pupils.
Spencer Lewis, executive headteacher of the Yavneh schools, said the primary school had received 152 applications in its first year of admissions. There are now 92 people on its waiting list.
Although, as a free school,Yavneh can only guarantee half of its places to Jewish children, the school would not elaborate on what the breakdown of Jewish and non-Jewish children will look like for September.
Mr Lewis said: “Our vision of providing first class Jewish and general education to children of 4-19 years is finally coming to fruition, and we could not be happier.”
After receiving the confirmation letter from Lord Nash, the school’s Local MP Mr Dowden added: “This is great news for the community, providing much needed additional primary school places.”
