The old Boys and Girls School opened in September 1842 and was located in the Priest’s Yard beside the church. There are very few records from this time, but in the 1885 edition of Wexford County Guide and Directory edited by George Henry Basset, John Jourdan is listed as Master of the Boy’s School and Ms. Anne Meyler as Mistress of the Girl’s School.
The first official records began in 1897, but on New Years Day 1900 a fire destroyed records from the Girl’s School, as well as some Parish records. Official records did not begin again until 1918.
In January 1933, the Office of National Education ordered both schools to amalgamate, due to low attendance numbers in the Boy’s School. This later became known as the Old  School. 
The total number of pupils listed on the Roll Books from 1897 t0 1932 was 540 boys and 348 girls.
In May 1949, the last classes to attend the Old School marched down the street in Adamstown to a brand new school.
