The
Ordnance Survey Ireland map 1837–1842 shows
Clonkeen School Ho[use], located in the present day
Cornelscourt Village. Although the same building appears on the OSI 1888–1913 map, it is not named as a school any more. The original junior school was St. Joseph's Private
Preparatory School, built in September 1965 close to where the present Clonkeen College stands. It was run by a staff of three
Christian Brothers until the school was closed in 1975. The secondary school was also called St. Joseph's, until renamed Clonkeen College. The present school stands on the site of
Charles Stewart Parnell’s second last public meeting. The first pupils to the current school were admitted in the autumn of 1970, there was one fifth-year class and two third-year classes (there was no fourth year then). Thirteen students completed the first
Leaving Certificate. The school principal was Br. Jo Hogan; other original teachers were Br. Collins and Mr. B. Toomey. The school was officially opened by
David Andrews TD on 31 January 1972. In 2019, Clonkeen College underwent substantial renovations, adding facilities including a gym, sports hall and new science classrooms. == Curriculum ==
