The Grange Academy is a co-educational secondary school and sixth form located in Bushey in the English county of Hertfordshire.

Ambitious expansion plans were drawn up by the county council, but were shelved on the outbreak of the Second World War.

[1] Around 1960 the Watford Technical High School moved to cheaply constructed buildings on the north side of Bushey Hall Road.

The buildings at the old Bushey Hall Road site remained derelict for 4 years before being demolished following a drowning in the old swimming pool.

These relate closely with other celestial detailing on the site; in the main entrance hall a stained glass roof dome is marked with the 12 signs of the zodiac.

The library was replaced in 1993 with the construction of a learning resource centre on the green space beside the gymnasium hall.

An arson attack in 1994 destroyed the gymnasium roof and it was closed due to lack of funds to replace the heavy timber trusses.
