The Billericay School is a mixed intake secondary and sixth form co-educational school for children aged between 11 and 18 (school years 7 to 13) . As of September 2004, the Student Body stood at 1673. The school has recent Artsmark and Sports Mark designations and has Investors in People Status.

The school is located in the town of Billericay, Essex in the United Kingdom of Great Britain and Northern Ireland. A school dating back to the early 20th Century, it originally had one building that is now recognised as 'A Block'. Over time The school has been developed and new school buildings have been raised upon existing school ground.

It is famous as the secondary school, which the comedian Lee Evans attended. The sixth form was visited in May 2006 by the MP Tony Benn who gave a speech on politics and political apathy. Other talkers who have visited school include the anti-fascist campaigner Leon Greenman who survived the Auschwitz concentration camp.

The 'block' buildings currently range from A to F, although mysteriously there is no 'B block'. The reason to this was actually that there was a 'B block’, which was believed to be used for scientific studies, but an unfortunate fire started within a science lab of the wooden built structure had caused the fire to spread quickly and to a point where there was irreversible repair. On this site currently stands one of the school's car parks.

In 2004, this trend was reversed when a 'V' block was created. It is thought that this refers to the concept of the block being a 'village' community. The V block was built partly in response to a fire which burnt down some of the buildings of 'D' block. However 2 of the 5 buildings still remain. Rumours circulate as to the cause of the fire; It was believed that it could have been an arson attack on the building, but the official explanation given was an “electrical fault” which caused fire to spread to other buildings.

The School achieved Maths and Computing college status in 2004 allowing some use of selection based on aptitude in these subjects. It was thought that this status would generate an additional £1 million worth of funding, but a government policy on foundation schools had reduced this sum significantly.

It is currently in the process of trying to sell the land adjacent to the school in order to raise funds for improvements to the school. This land was used for rural sciences when this formed part of the curriculum. There has been opposition to this as the land forms part of the green belt.

Between 2005 and 2006 the school made changes to its day structure. This involved cutting the lunchtime by 15 minutes reducing it to 45 minutes. In 2006 the school announced it was to split into houses groups. The houses are to be named after famous scientists.
