The civil service was the best source of employment for those who received further education. Lack School has a good record, with 31 past-pupils obtaining employment in the public service from the late 1940s up to the late 1960s. The education was obtained mainly in one of the secondary schools in Ennis or the Convent of Mercy, Templemore, County Tipperary, which specialised in preparing girls for the civil service examination. The employment was exclusively in the Dublin area.

Vera Gavin, Ardnagla
Vera Gavin from Ardnagla holds the distinction of being the first pupil from Lack School to sit the Leaving Certificate examination. Vera registered at Lack School in 1931.
She obtained her secondary education at Coláiste Mhuire, Ennis and entered the civil service in 1946. She was assigned to the Department of the Taoiseach. Having worked there for 13 years, she resigned on her marriage to Michael Bermingham in 1959 and moved to Doonbeg, County Clare, where she remained until her death in 2009.

James Hehir, Lack
Marie Clohessy from Ardnagla holds the distinction of being one of the first persons in the history of the state to hold the position of Equality Officer. Marie registered at Lack School in 1952. She obtained a county council scholarship to assist in meeting the cost of her secondary education, which she obtained at Coláiste Mhuire, Ennis. She entered the civil service in 1966 as an executive officer and was assigned to the Department of Labour.
On the passing of the Equality and Equal Pay Acts by the Oireachtas, Marie was appointed as one of the first equality officers with the responsibility of implementing this new legislation.
She resigned from the position in 1980 to attend to the rearing of her children and later returned to her home parish taking up residence at Lavalla. In the period since 1995 she has been employed by the Clare County Library service.
