In March 2008 Hasmonean was singled out as one of the faith schools in the news for its procedure of demanding contributions from parents as a condition of entry.

In that year, the boys' school moved to Holders Hill Road, where it has remained until the present day.

As of September 2011, the bus route 240 serves the boys site of the school, with access to Golders Green, Edgware and Mill Hill Broadway Stations for all students.

The current chairmen of governors are Gary Swabel (MAT), Yossi Halberstadt (Boys) and Steven Blumgart (Girls).

The three campuses share leadership teams and teaching staff, but, in accordance with Hasmonean's ethos, the educational accommodation, external spaces and play areas are separate.
