Katherine Warington School opened in September 2019 to address a critical shortage of secondary places in Harpenden. Named after the pioneering plant physiologist who worked at the nearby Rothamsted Research, the school has established itself as a formidable addition to the local educational landscape. It serves a community accustomed to high academic standards, and recent performance data suggests it is meeting those expectations comfortably.
With a Progress 8 score of +0.48, students here make significantly more progress than their peers across England. This is a school built on a foundation of contemporary facilities and a curriculum that leans into the scientific heritage of its location. David Martin, the Headteacher who took up his post in February 2024, oversees the school's growth into a full secondary and sixth form provision, maintaining a focus on core values of knowledge, integrity, and pride.
The atmosphere at Katherine Warington School is one of purposeful modernism. Being a recent build, the site offers a bright, tech-forward environment with functionality and space specifically considered.

The culture is influenced by its namesake's legacy. There is a palpable emphasis on curiosity and the scientific method across the curriculum.
