The school was established in 1974 by a merger of Fylde Lodge High School, which was located in Priestnall Road, Heaton Mersey, and Stockport High School for Girls, which was located in Cale Green. Priestnall School took over the Fylde Lodge High School building. The Stockport High School building was subsequently used first by Davenport High School, then by Hillcrest Grammar School from 1983.[2]
Fylde Lodge High School was built in the 1960s as an all girls school. It was still an all girls school at the time of the merger. Males were allowed to study at Priestnall School from 1987. Priestnall still to this day keeps some heritage of Fylde Lodge.
Previously a community school administered by Stockport Metropolitan Borough Council,[3] in September 2023 Priestnall School converted to academy status.[4] The school is now sponsored by The Laurus Trust. Prior to the Laurus Trust sponsoring the school the school was led by two Acting Headteachers (Mr Timothy Clarey and Mr Robert Jones), this was for the period April 2023 to September 2023.[5]
