Westhill Academy opened in the autumn of 1979 with buildings designed to accommodate 500 pupils. The school was extended in 1982 and then again in 1996 raising the capacity of the school to 1000 pupils. The roll of the school, in recent years, has fluctuated between 890 and 1200 pupils. In 2019 the school celebrated its 40th anniversary. It was celebrated by inviting current and ex staff members to look at year books and to see how it has changed through the years.
