St Columba's College is located 25 miles from central London in the Cathedral city of St Albans, Hertfordshire. It is a thriving HMC, Catholic independent day school for students aged 4-18. There are 195 pupils in Prep and 590 in the Senior school of whom 150 are in the Sixth Form.

Columba's is an academic and aspirational school with a mixed ability intake devoted to scholarship and holistic development of each individual child. The College challenges students to the best they can be in intellectual achievement and their person and character. Formation of the whole child is at the core of the school's educational philosophy.

The school is at an interesting and exciting phase of its history as it transitions from an all-boys establishment to one that is coeducational.
