With the removal of the Direct Grant, the school became independent in September 1976 under the headship of David Richards. In the same year, the governors accepted the principle of co-education and the first girl was admitted to the school. In the following year the Pre-Prep department opened. By 1978, the school had 920 pupils in the Upper and Lower Schools.
In 1979, Saturday mornings was dropped from the school timetable.
