High master (academic)
High master is the term used, in place of the more conventional "headmaster", "head teacher" or "principal", to denote the head teachers of two English public schools: The [Manchester Grammar School] and St Paul's [School, London |St Paul's School] in London. Two notable high masters of both schools were Frederick William Walker, who served at Manchester Grammar 1860–1877, and St Paul's 1877–1905; and Martin Stephen, who served at Manchester Grammar 1994–2004, and St Paul's 2004–2011. The incumbent high masters of Manchester Grammar and St Paul's are Martin Boulton and Sally-Anne Huang respectively.
The equivalent high mistress is used for female headteachers at some independent schools, including St Paul's Girls' School and Abercorn School.
