St Swithun's moved to its present location on Magdalen Hill Down on the edge of Winchester in 1931.

[1] Today, St Swithun's includes both junior and senior schools, meaning pupils can attend from nursery all the way to sixth form level.

St Swithun's retains a strong Anglican tradition through its links with Winchester Cathedral.

The house system is an integral part of school life as there are inter-house competitions in many co-curricular activities such as sports, public speaking and drama.

[10] St Swithun's has a strong sporting tradition and has enjoyed success at county level and inter-school competitions.

[11][12][13] Girls are encouraged to take up a sport and may choose from athletics, badminton, basketball, cricket, lacrosse and netball, Zumba, handball, trampolining, touch rugby, tennis, pilates and fitness.

[14] As for many other independent schools, candidates for entry to St Swithun's must sit the Common Entrance Examination.

Sixth form scholarship candidates (16+) are selected based solely on the results of academic assessments in the subjects that they intend to take at A level.
