 Halesowen was absorbed by Dudley (which had adopted 5-8 first and 8-12 middle schools in 1972) in April 1974, but the system in Halesowen continued until September 1982, when the traditional age ranges were reinstated, although the remaining parts of Dudley did not revert to this system for another eight years.Leasowes became an 11-16 comprehensive as a result of this reorganisation, resulting in the closure of Greenhill Middle School.The three oldest year groups at Greenhill moved up to Leasowes, while the youngest year group were transferred to Olive Hill Primary School.
