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 school's size had tripled. It was now clear that additional facilities would be needed. In September 1973 St. Columb's College opened a new campus on the Buncrana Road in the city. The new site would cater for the senior years; its initial enrolment was of 900. The new building was designed by Frank Corr of Corr & McCormick and constructed by J Kennedy & Co. The total cost was £762,000. This figure does not include the £56,000 spent employing W & J McMonagle Ltd to construct the playing fields. == Sport ==
