The school's origins lie in The Harpur Trust, founded on endowments left by Sir William Harpur, a Bedford-born Lord Mayor of London, in the 16th century. In 1764, following separation from Bedford School, the institution began operating under its own name. It subsequently traded under several names: the Writing School, the English School, the Commercial School and finally Bedford Modern School, the last change being made in 1873 to reflect a curriculum oriented towards the professions rather than the church.
The school established a reputation for academic ambition, attracting pupils not only from Bedfordshire but also military and colonial families seeking high-quality education for their children.
During World War II, Dame Alice Owen's School was evacuated to BMS for the duration of the conflict. The school's swimming baths were also used during this time by inventors Cecil Vandepeer Clarke and Stuart Macrae to test prototype limpet mines. Clarke was an excellent swimmer and was able to propel himself through the water with a prototype bomb attached to a keeper plate on webbing around his waist.
The school's Prichard Museum, a collection of artifacts sent back to the school mainly from old boys around the world, became Bedford Museum, now The Higgins Art Gallery & Museum. George Witt was a major benefactor to the school's museum.
Growing enrolment eventually made the Harpur Square premises too cramped, and in 1974 the school moved to its current site on Manton Lane. The foundation stone was laid by Margaret Thatcher, and on 11 May 1976, Queen Elizabeth II visited with Prince Philip to unveil a commemorative panel at the new building.
Originally a boys' day and boarding school, Bedford Modern became fully co-educational in 2003 following the closure of its boarding houses. In 2013 BMS celebrated 10 years of co-education, with a play written by Mark Burgess commissioned to celebrate the event.
In 2014, the school celebrated the 250th anniversary of its separation from Bedford School.
In September 2023, Bedford Modern School was among the schools across the United Kingdom found to contain reinforced autoclaved aerated concrete (RAAC), a lightweight building material widely used in construction between the 1950s and 1990s that has since been found to be prone to sudden structural failure. The school's main block, built as part of the 1974 development, was identified as containing the material.
In November 2025, the school submitted a planning application to Bedford Borough Council to demolish a section of its main block affected by the RAAC. The proposals included replacing it with new façades to the exposed elevations, a new tennis court in the resulting courtyard, a new glazed northern entrance, and a glazed canopy along the northern elevation.
School houses
Following a tradition of over a hundred years the Senior School Houses of BMS were: North, South, East, West, County and United Boarders. United Boarders comprised the combined boarding houses: Culver, Shakespeare, and School House. The day boy houses often, though not always, reflected the parts of the town or county from which the boys hailed and were mentioned in the chorus of the school song.
Today, the senior school operates six houses, introduced in their current form in September 1998. Each house is named after an Old Bedford Modernian of national or international distinction, chosen through a school-wide competition. The houses are Bell, Farrar, Mobbs, Oatley, Rose and Tilden.
The junior school operates four different houses, each named after a former headmaster. Kaye (green, named after Cecil William Kaye, 1901–1916), Liddle (blue, named after Henry Weddell Liddle, 1922–1946), Poole (red, named after Robert Burton Poole, 1877–1900) and Taylor (yellow, named after John Edward Taylor, 1946–1965).
Each house has its own tie which consists of stripes of the three school colours and their own house colour. Inter-house sports competitions cover many sports run by the school, at both junior and senior level, such as rugby, football, cricket, netball and hockey. There are also non-sporting events such as quizzes and Music and Drama competitions. Students take leadership roles as house captains or house deputies.
Monitors

Monitors are selected, following a written application process, from students in the upper sixth. Each team of monitors works with a specific year group, and are led by two senior monitors, appointed by the headmaster. Senior monitors, along with the heads of school, are entitled to wear a red trim on their blazer.

The school maintains extensive sporting facilities, including a rowing boathouse on the River Great Ouse, rugby and cricket pitches, tennis and netball courts, a swimming pool, athletics track, climbing wall and strength and conditioning gym. The shooting range was closed and demolished to make space for the new science block in 2014.
The school puts on two major productions annually, normally musicals, with full orchestra and set, in its 300-seat auditorium. It also hosts its own Shakespeare Festival, in which local schools are invited to take part. The sixth form has its own theatre company, Theatre in Transit, which puts on a piece of theatre each year at professional venues. In September 2014, the Chamber Choir performed The Armed Man at the Royal Albert Hall as part of Sing UK's 'A Mass for Peace'.
Combined Cadet Force
The BMS Combined Cadet Force was established in 1900 and comprises the Royal Navy, the Army and the Royal Air Force. The Royal Marines section was closed in 2018. King George V addressed the Bedford Modern School CCF in 1918.
Eagle magazine
The Eagle, The Magazine of Bedford Modern School, first published in 1881
The school has several of its own publications, the most prominent of which is named The Eagle, first published in 1881.
Published mostly biannually, it serves both as a school magazine and a record of life at BMS during each academic year. The Eagle is predominantly designed and edited by sixth form students, and since 2000 is printed as a glossy magazine with around 48 pages. It often also includes feature articles and interviews with former students.
In addition to The Eagle, other publications include The Eaglet, which, until recently, was included as part of the main magazine, and includes articles from the Junior School.
Another publication is the Eagle News, which is published for the benefit of OBMs. It includes School news, and follow-up articles of former pupils. In 1906 the mathematician Eric Temple Bell reported news of an earthquake in San Francisco, where he was resident at the time.
