Job Description

About the School - The British School of Barcelona (Castelldefels):
The British School of Barcelona (BSB) is a great school in a wonderful location. We are an HMC school and were judged by a recent BSO (British Schools Overseas) inspection to be outstanding in every area, including quality of education, safeguarding, pupil welfare and academic outcomes.

BSB is a large, very popular school for children aged 3 to 18. Our curriculum is based on the English National Curriculum, and we offer a wide range of GCSEs, A levels and the International Baccalaureate Diploma, all alongside a significant enrichment programme.

Over 2000 pupils from more than 74 nationalities attend the school and over 315 staff work at BSB. We are based in three locations, two just outside the city of Barcelona – in Castelldefels, where we have a Primary, Secondary and Pre-University campus, and in the cosmopolitan town of Sitges, where we have another Primary campus. BSB City is in the heart of the city of Barcelona itself with a Foundation campus (built September 2021), and a brand-new main campus which opened in September 2023.

The growth of the school has been accompanied by significant investment over recent years, including the building of a state-of–the art Pre-University Centre (Nexus), a full-sized 4G rugby and football pitch, dedicated STEM facilities and the new BSB City campuses.

Barcelona is a wonderful place to live, combining an amazing city with beach and mountains nearby. The quality of life is excellent with a mild climate and year-round sunshine.

The school now has an exciting opportunity for an experienced Secondary Biology Teacher to join our fantastic team.
