Wrenn School traces its history back to the 1907 establishment of the Wellingborough Grammar School for Girls and arose from the merger of that school with Wellingborough Grammar School, opened in 1930. The now comprehensive

Wrenn School opened in September 1975, having been named after the final Headmaster of the grammar school, Mr Wrenn.

The Wellingborough Grammar School for girls was opened at The Lindens in Midland Road by the governors of Wellingborough School to offer a ‘higher education to girls from comparatively ordinary backgrounds.’ In its first year it had 7 staff and welcomed 28 girls.

The school developed such that by 1911 the county council had taken over its running and it relocated to the impressive site on London Road, now the upper school section of Wrenn School, welcoming 105 girls.

The school continued to develop under the leadership of Miss Tinkler (1907-1937), Miss Schofield (1937-44), Miss Horton (1944-1968) whose term of office saw a number of initiatives introduced to raise funds for the opening of the swimming pool in 1960. The school’s final Headteacher, Miss Hubbert (1968-75), would go on to be the first Headteacher of Wrenn School.
