City of London School (CLS) is a popular London-based independent day school for boys, located opposite Tate Modern. One of the nation’s top-performing schools, City was founded in 1834 and boasts a long list of notable alumni, better known as Old Citizens. Its facilities are modern and spacious and include a 25-metre swimming pool, a multipurpose indoor sports hall, a rooftop football pitch and extensive playing fields. [1]


Benefitting from a rich range of academic opportunities, City’s pupils are known to excel across the abundant curriculum. Subjects on offer range from English, MFL and politics to science, Latin and design computing, including extras such as the Extended Project (EP), which helps students develop university-style research skills.


An array of clubs and societies form an integral part of the co-curricular programme, aimed at comprehensively improving each student’s non-academic abilities. School trips to thrilling destinations, such as Nepal, Vietnam, Ecuador, Cuba, China and the States, further enhances the versatility of pupils, exposing them to a variety of cultural settings. [2]


CLS is noted for the success of its community-related initiatives such as the Green Schools Project, which focuses on transforming the school into an environmentally-aware institution. Volunteering is another popular activity, allowing students to contribute to society and maximise their awareness of the needs of others. [3]


Distinguished institutions, such as the University of Cambridge, the University of Oxford, the University of Edinburgh, Durham University and the University of Sheffield, alongside the top 25 American universities, frequently feature on the list of leavers’ destinations. City’s exemplary academic standing is further underlined by recent GCSE results, where an impressive 97% of students secured the top-tier 9-7 grades.
