St Columb's College () is a Roman Catholic boys' grammar school in Derry, Northern Ireland and, since 2008, a specialist school in mathematics. It is named after Saint Columba, the missionary monk from County Donegal who founded a monastery in the area. The college was originally built to educate young men into the priesthood, but now educates boys in a variety of disciplines. St Columb's College was established in 1879 on Bishop Street (now the site of Lumen Christi College), but later moved to Buncrana Road in the suburbs of the city. Early history St Columb's College was preceded by several failed attempts to create such an institution in Derry. Repeated but sporadic efforts were made to maintain a seminary for almost a century; at Clady, near Strabane, in the late eighteenth century, at Ferguson's Lane in Derry in the early nineteenth century and at Pump Street (first reference to St Columb's College as such) in the city from 1841 to 1864. St Columb's finally opened its doors on 3 November 1879 with two priest teachers, Edward O'Brien and John Hassan. The school was considered to be quite large at the time and was expected to accommodate 20–30 boarders. The school quickly gained a reputation for academic achievement. On 18 September 1931 the Derry Journal listed St Columb's College's academic results. They were as follows: 2 university scholarships 3 exhibitions and prizes 6 calls in King's Scholarship exam (calls to teacher training) 2 pupil teacherships 8 regional committee scholarships 31 passed matriculation 26 passed Senior Leaving Cert. exam 52 passed Junior Leaving Cert. exam The Education Act 1947 and expansion One of the most notable alumni of St Columb's College, John Hume, noted, "When the history of St. Columb's College in this century is written, it will be clear that one of its major transformations, if not its major transformation, took place as a result of the Eleven Plus examination." The Education Act 1947 provided for free secondary education to all throughout the United Kingdom. Entry to St. Columb's College, a grammar school, would be determined by one's performance in the 11-plus or Transfer Test. The immediate result was an explosion in pupil numbers, a shortfall in teaching staff and greater pressure on existing resources. In 1941 the student body numbered 263. By 1960 the number stood at 770 with a teaching staff of 35. In under twenty years the
