Kingsbury Technical School (a mixed technical school) and '''Queen Eleanor's Grammar School for Girls
merged in 1972 to form Queensbury Upper School''', when Bedfordshire changed from a two-tier school system to a
three-tier system. The first Headteacher at Queensbury was Christina Scott, who served for twelve years from 1972 until retiring in 1984. Scott was succeeded by Keith Barker, whose tenure saw a period when the school was flagged for closure. However, the local community, including Member of Parliament
David Madel, fought to keep Queensbury open and took advantage of the grant-maintained system introduced in 1988. Thus, Queensbury became the second
grant-maintained school. Barker left his position in 1994 and was replaced by Bob Clayton. Grant-maintained schools were abolished in 1998 during Clayton's tenure, so Queensbury was converted to a
foundation school. During its ten years as a grant-maintained school, it grew from having meagre enrolment numbers to being heavily oversubscribed. After Clayton left his post in 2003, Deputy Head Lynn Morgan briefly served as Interim Headteacher until the arrival of Nigel Hill. During his first year as Headteacher, Hill decided to replace sugary snacks in vending machines with healthier alternatives, which gained national news attention. Hill departed in 2012 after the school was placed into special measures by
OFSTED, leading to the interim appointment of Jill Coughlan
CBE as Headteacher to oversee Queensbury's conversion to an
academy. This change came into effect in September 2012, and Oliver Button became the first Principal of the newly renamed Queensbury Academy. He served until 2019 when he departed and was replaced by Assistant Principal Mark Little. In October 2022, Anthem Trust announced that Little was leaving his role as Principal at the academy. Helen Palmer was announced as the Interim Headteacher, alongside a number of changes to the school day. Helen Palmer was later made permanent Headteacher of Queensbury Academy in April 2023. == School site ==
