The Liberal Jewish Synagogue Nursery School has been upgraded from "good" to "outstanding" in its latest Ofsted inspection.
Inspectors, who dropped in unannounced on the nursery - which is situated inside the liberal synagogue in St John's Wood - in July, marked it as "outstanding" in all areas.
They said that "the staff and management team focus significantly well on their work with children" and "an excellent commitment to accurate self-evaluation results in staff implementing highly effective action plans across the nursery".
Other areas they commended were the staff's relationship with parents, and the safety of all its pupils.
