St. Mary’s Secondary School Edenderry is a Catholic School held in trust by the Kildare and Leighlin Diocesan Trust and under the patronage of the Bishop of Kildare and Leighlin. The purpose of the school as a centre of post-primary education is to help the students to take their place in society as educated, mature and committed Christians with a philosophy of life which is spiritually enriching and which will enable them to contribute positively to the society in which they live. The school authority wants the school to be, not only a centre of academic excellence, but a community animated by the spirit of the Gospel, where personal faith is nurtured and developed.
The educational programme of the school is directed to the growth of the whole person, and has its source in a Christian vision of reality. The Principal/Teacher who joins the school community must be willing to take his/her share of responsibility in the formation and education of young Christians. This calls for witness to and support for the Catholic ethos of the school and its educational programme.
