Cranbourne was founded as the Cranbourne Bi-Lateral School in 1967 as a bilateral school for 11- to 18-year-olds, on the site of a former nursery. It became a comprehensive school in 1972 following the establishment of Queen Mary's Sixth Form College, and then as Cranbourne Business and Enterprise Collegein September 2004. Cranbourne became the first of two Business and Enterprise Colleges in Hampshire in 2004 and features scola architecture refurbished in 2006. CBEC is separated into 9 blocks and features a small swimming pool and a 3-story Science block. The School changed its name to Cranbourne in September 2018 introducing a new Logo and Uniform.
Cranbourne introduced a new House System and Vertical Tutor Groups in September 2018. Cranbourne students are members of one of our four Houses. Each House has House Captains, Sports Captains and House Mentors to encourage and support every student. Each House has a Head of House and a Cranbourne Parent Partner overseeing each student’s progress and pastoral care. Cranbourne’s four Houses are dedicated to local people, who have achieved amazing things by following their passions and interests. They are true role models for Cranbourne students.
At the end of the 2015-2016 academic year, Headmistress Betty Elkins resigned and Jane Aplin took over as Head. There are plans to merge the students of Fort Hill Community School with CBEC's due to low numbers at Fort Hill. At the county councils decision in June 2017, it was recommended and approved that Fort Hill will close on 31 August 2017. All Fort Hill pupils will start at Cranbourne in September 2017. Parents who received a place at Fort Hill for their child have been automatically given a place at Cranbourne.
