Grammar school

Originally called Apsley Grammar School, it began as a state grammar school in Hemel Hempstead. It was founded in 1955 as part of the development of the town after its designation as a new town and the need for expanded secondary school provision. Although named for the nearby village of Apsley the school is actually situated about one mile away, in the Bennetts End district of the town. Its first Head Teacher was Valentine (V.J.) Wrigley.

Comprehensive

The name of the school changed to Longdean School in 1970 on the amalgamation with the adjacent Bennett's End Secondary Modern School to form what was the third-largest comprehensive school in Hertfordshire at the time.

The school motto of Rejoice in Thy Youth was retained after the amalgamation.

Since September 2012 the headmaster has been Mr Graham Cunningham, replacing the previous headmaster, Mr Rhodri Bryant. The last Ofsted report classed the school as a 'GOOD'.

The school operates community facilities in the form of a sports centre, small Astro pitch, grass pitches and Multi Use Games Area.

Academy

During the summer term of 2011, Longdean School attained academy status.

The school works in consortium with two neighbouring schools to enhance post-16 provision. The group consists of Adeyfield Academy, Astley Cooper School and Longdean School. Staff development and well-being are also coordinated at consortium level.

In May 2012, Longdean was included in the Government's £2 billion Priority School Building Programme.^[1] Longdean's inclusion was based upon the condition of its existing buildings that have exceeded their 25-year life expectancy. As a result, a completely new school building was constructed by Interserve/Kajima^[2] on former playing fields and both the existing premises were demolished. The new school opened at the end of 2016.
