The Association of Head Mistresses of Endowed and Proprietary Schools was founded in 1874 by Miss Frances Mary Buss, Head Mistress of the North London Collegiate School for Girls. There were thirteen members. She was first President of the Association holding office from its foundation until her death in 1894, when succeeded by the other great 'pioneer' headmistress, Miss Dorothea Beale of the Ladies College, Cheltenham.
In 1896, when there were 166 ordinary women members, the Association became incorporated with the title 'The Association of Head Mistresses, Incorporated 1896'. In 1959 membership had risen to 892 ordinary members, including Head Mistresses of 'approved' secondary schools. [MSS.188/3/6/1].The Association merged with the Association of Headmasters on 1 January 1978 to become the Secondary Heads' Association.
Archives of academic and financial interest have also been deposited with the North London Collegiate School for Girls by the Association of Head Mistresses. Miss Buss was founder and Head of the school as well as founder of the Association.
