In 1938 a new Council Senior School was opened in Shefford for older children from the town and surrounding villages. The third of the great Education Acts was that of 1944 which established the principle of County Primary Schools for children up to the age of 11, at which time they took an examination to determine the nature of the secondary school they would attend until they were 15, the most academically able going to grammar schools, the rest to secondary or secondary modern schools. In 1946, when the act came into force, Shefford Council Senior School became Shefford County Secondary Modern School. The name changed to Robert Bloomfield County Secondary Modern School in the 1950s and in 1958 a two-storey extension was added to the school buildings.
In the 1970s Bedfordshire County Council introduced comprehensive education, doing away with the 11+ examination and grammar schools and introducing a tier of school between the old County Primary and County Secondary Schools. Robert Bloomfield CSM became Robert Bloomfield Middle School, for children aged 9 to 13 who at the latter age go on the Samuel Whitbread Upper School just over the parish boundary in Clifton.
In 2010, RBMS became one of the first new academies and gained a teaching school designation. The name was changed to Robert Bloomfield Academy.
