The curriculum is broad and challenging, encouraging boys to embrace academic ambition while developing independence and analytical thinking. Teaching is supported by modern facilities including science laboratories, a Sixth Form centre, a music department equipped for both classical and contemporary study, and a well resourced library. The school also benefits from additional teaching and sports spaces across its Marylebone campus, including facilities shared with its partner preparatory schools.

Co-curricular life is an integral part of the Wetherby Senior experience. Pupils engage in a wide range of activities including debating, coding, orchestra, drama, Model UN, and academic societies. Sport plays a prominent role, with football, cricket, rugby, athletics, and basketball among the most popular options. Matches and training take place at high quality sports grounds in West London. Outdoor education and Duke of Edinburgh’s Award also feature strongly, supporting leadership, teamwork, and resilience. Pastoral care is a defining feature of the school, based on strong relationships, a house system, and personalised support designed to help boys develop confidence, wellbeing, and maturity.
