History of Deele College
In 1958, the provision of another school in Raphoe in addition to the existing Royal and Prior School was recommended. This would eventually become Deele College which opened on 29 March 1965 (by the Minister for Local Government at the time, Neil Blaney, T.D.) on two acres and on which the school stands today, albeit with a further seven acres added to it on which the school building was extended in 1985. One of the highlights for Deele College in recent years came in November 2002 when Her Excellency, Mary McAleese, Uachtarann na hEireann visited the school. Other such visitors to the school have included Nobel Prize–winning politician John Hume and former head of Coca-Cola and television personality Gerry Robinson . Students who have attended the school have gone on to many in third level institutions all across Ireland and the UK in recent years. 
The school contains first class sporting facilities with a gym, three pitches (one of which is astroturfed). Prefabricated Accommodation was erected at the school in 2008. A school library was constructed in 2009 and a new staff room is to be completed in 2010
Due to increasing number of students attending Deele College, provision has been approved for a new extension to the school, costing approximately €3 million. The new extension will consist of 2 new floors added to the school, linked via a corridor connecting to the old school building. New science facilities, art room and computer labs are just a few of the many facilities that will be provided. As of January 2013, the design plans have been complete and approved by the Department of Education and Skills. The extension will also provide a fitness suite for the adjoining sports hall. The extension is due to be complete by September 2014.
