school, now having to cope with both its new status as a comprehensive school and the raising of the school leaving age to 16. The new buildings provided a gym, indoor swimming pool and additional classrooms for art, pottery and other uses. New extensions were added also to the 1935 block, at the side-rear of the two halls. In 1974, a small block opposite the main building opened, formerly known as the 'ROSLA' (Raising of the School Leaving Age) block. It provided accommodation for the more academically able pupils, as Chesterton was a secondary modern school, for children who did not pass the 11-plus tests, and thus did not become a grammar school. The 'ROSLA' block now houses the school's science department. In 1992 a new high-tech extension was built to provide the school with a new library, computer facilities, new classrooms, new staff accommodation, and also to provide the school with a new reception and entrance. It was named The Newall Building, after former and now retired principal A. B. Newall. It was designed by Johns Partnership. The science block also received an extension at this time, adding two new classrooms and a preparations room. Johns Partnership also designed the new music block at the rear of the site, which provided a main performance room, classroom and practice suites. The building was purpose-built and was acoustically engineered. It featured a sundial on the front facade in memory of a former head of mathematics, Terry McConkey. In 2004, a new sports complex was built, providing a large sports hall, fitness suite, café, changing facilities, function area, floodlit tennis courts and reception area, as well as refurbishment of the existing swimming pool and gym, housed in the adjacent '60s buildings. The new sports centre is also used by the general public. The building was designed by Cambridgeshire County Council Design Team, and cost £2.9 million. The National Lottery, Cambridgeshire County Council and the school donated and raised money for the new building which opened in October 2004 by sports personality and heptathlon athlete, Caroline Pearce. However, the sports centre went into deficit by £150,000 in 2010. The college has been in bitter dispute with public users and community leaders after their swimming sessions were axed. The swimmers said they would be prepared to pay more money, but the college authorities have declined their offer and sacked five members of staff in
