Abbotsgrange Middle School and Moray Middle School were schools that operated in Grangemouth, Scotland, between 1974 and 1988. They were the only two middle schools in the whole of Scotland and Grangemouth remains the only area of Scotland where experimentation in three-tier education was ever tried. Grangemouth is in the historic county of Stirlingshire in central Scotland and, following local government reorganisation in 1975, became part of the Falkirk District of the Central Region.
