Leweston provides a curriculum that, in keeping with the School's ethos, ensures for each of its girls balanced, appropriate and interesting opportunities for academic study. It is intended and planned to instil a love of learning and to inspire the life of the mind. The focus is to enable pupils to achieve the best possible academic success. Broadly, pupils in Years 7 to 11 are taught in the fields of linguistic, mathematical, scientific, technological, human, social, moral, spiritual, physical, aesthetic, and creative knowledge and the School, throughout its curriculum, educates for high standards of speaking, listening, literacy, and numeracy.
The School includes in its core provision English, History, Geography, HEF, Maths, Science, PSHE and RE, Drama, Classical Studies or Latin, Music, one Modern Foreign Language, and PE. While traditional in the rigour and range of the subjects and teaching, in keeping with the 'contemporary' aspect of the School's Mission Statement and the School's intention to prepare girls for life beyond Leweston, the curriculum is considered, developed and changed to suit the academic needs of girls in a given year on an annual basis.
