In 1921, the school was bought by Miss Norris, who set about a programme of modernisation and enlargement which continued under the supervision of succeeding headships.

In the year 2000, under the headship of Miss Juett, a new indoor swimming pool, sports hall, fitness studio and senior library were opened.

However, very little interaction took place between the two institutions other than co-hosting a Sixth Form Prom and an invitation to participate in the annual theatre production, which suited the more dramatic students.

Subsequently, John Lyon School made links with Northwood College with a programme designed to enable boys and girls to interact.

Such events include joint quizzes, debates, book discussions, cookery workshops, theatre trips, gallery visits, careers evenings, newsletter and inter-school competitions.

In 2013, iPod Touch devices were given to students with relevant apps uploaded in order to incorporate technology in class, in the name of e-learning.

From Lower Kindergarten (nursery) through to the Sixth Form, each girl belonged to one of four houses: Brontë, Curie, Nightingale or Pankhurst.

The houses represented pioneering women, whose stories were repeated to the girls every year, serving as role models to students.

Moreover, as a GDST school, female empowerment was integral to the fabric of the school, with the majority of assemblies and the curriculum tailored around women growing up in a stable environment[clarification needed] with an understanding the significance of the sacrifices by the Suffrage Movement, achievements by women, and how to enhance their prospects in order to break the glass ceiling.
