Records show that there was a school functioning in 1864 near where the N17 Electrical Store is today. Its first master was James Corcoran, succeeded by Martin Mannion, Julie Smyth and Ellen Geraghty.
In 1881 the “old” school on this site was built on land donated by Jack Tierney. It had one room at first, later enlarged in 1900 with an enrolment of 138 pupils. There was no compulsion on children to attend. There was low attendance at harvest/spring time.
By 1970 the physical condition of the school building was diminishing. Windows and doors were in desperate need of repair. By July the 4th, the construction of a third school in just over a century got underway. The old school was demolished to the ground and the new school was open on the same site and finally completed on November the 20th, 1972. The school consisted of three classrooms and Mrs. O’Connor became principal.
In the 1990’s, Dalgin N.S. closed. They amalgamated with Belmont N.S. and a school bus was put in operation to bring children from the Dalgin area to Belmont N.S.
The first principal was Ellen Geraghty. Second principal was James O’Kane, followed by Michael Acton, Christy Molloy, Seán Callaghan, Kathleen O’Connor, Eleanor Sheridan & Martina McGrath.
