Service Selection Boards and meet minimum academic requirements. Candidates had to be British citizens, or hold dual-nationality with one being British. Candidates were required to have an A grade in GCSE maths (or equivalent), a B grade in the equivalent level science, and a C grade in the equivalent level English language. A 2018 Independent Schools Inspectorate report noted that pupils at the school came from a very diverse range of backgrounds from across the United Kingdom. A similar report in 2014 noted that just under a quarter of the students were girls. A small number of private pupils were admitted annually, who paid £6,900 per term during 2019/2020, although the majority of students were classified as 'sponsored students' and had their tuition fees paid for by the Ministry of Defence. All students' parents were expected to contribute toward maintenance costs, including board, lodging, uniform, and any other services provided, though the amount varied based on gross annual household income and several other factors. Curriculum Structure Aiming to prepare students for careers in the armed forces, the school focused primarily on science, technology, engineering, and mathematics (STEM) subjects, and, shortly before its closure, offered a choice of 11 core subjects. Before its closure, all students were required to take four AS-levels in lower-sixth, including mathematics and physics, and all had to continue mathematics at A-level in their final year. An enrichment programme was also available, whereby students could attain additional qualifications such as developing language skills or completing an Extended Project Qualification (EPQ). A 2018 Independent Schools Inspectorate (ISI) report noted that A-level results from 2014 to 2016 were above the national average for sixth formers in maintained schools, similar to the 2014 ISI report which further found that over two-thirds of results were graded A* to B in 2013. Pupils of the school were given preferred entry to the Defence Technical Undergraduate Scheme (DTUS), which aimed to further prepare students for careers in the armed forces. Pupils typically went on to read science, engineering or management degrees at one of 11 universities on the scheme. Combined Cadet Force Unlike most schools, participation in the school's combined cadet force (CCF) was a compulsory part of the curriculum for all students. The school CCF did not follow the usual cadet training programme, instead holding sessions twice per week and placing more emphasis on skills and leadership, in order to better prepare
