Admissions at age 16 to the Sixth Form requires high enough GCSE grades but no formal exam. History The Princess Mary High School (which was known as Halifax High School for Girls before 1931) had around 350 girls and was opened on 21 September 1931 by Princess Mary. It became known as the Princess Mary School in 1969 and was situated on Francis Street. There was a Service of Thanksgiving in July 1985 at the Halifax Parish Church when the school amalgamated with The Highlands School to become North Halifax High School.The buildings remained in use as part of North Halifax High School, though with some facilities used by the Percival Whitley College, until in 1987 all school pupils moved to the former Highlands School site and the buildings were taken over by the College, later becoming part of Halifax New College (which eventually became Calderdale College when it combined with the Halifax School of Integrated Arts). The site is currently scheduled to be demolished and redeveloped. The Halifax Technical High School was formed in 1957. This was before its Moorbottom Road premises were completed and opened in May 1959 by the Vice-Chancellor of the University of Leeds. It had around 725 boys and girls. It became the Highlands School in 1969. Amalgamation The North Halifax High School was formed with the 1985 amalgamation of the Highlands Grammar School and the Princess Mary School.
