About St. Mary Catholic School

We are Proud!




St. Mary Catholic School in Centralia Illinois, founded in 1867, offers Pre-Kindergarten through Grade Eight education to members of St. Mary Parish and the community. In partnership with the parents and guardians, St. Mary Catholic School provides a Christian atmosphere that allows for the development of the whole child, striving to nurture acceptance, respect, self-discipline, and responsibility. Loving and caring for others are fostered through the teaching of the Catholic Faith and the living of Christian values. St. Mary Catholic School, a leader in the community, is dedicated to high standards of personal and academic achievement so that the students may reach their fullest potential. 



Since every man and woman of whatever race, condition and age is endowed with the dignity of a person, he / she has an inalienable right to an education corresponding to his / her proper destiny and suited to his / her native talents, sex, cultural background and ancestral heritage. At the same time, this education should pave the way to friendly association with other peoples so that genuine unity and peace on earth may be promoted. 

The school faculty must provide for its students an atmosphere conducive to learning. They must be continually ready to renew and adapt themselves and their methods so as to better carry out their teaching vocation; they must also be totally committed to the process of Catholic education. 

Although several agencies cooperate in the task of Christian education, the first and foremost educators are the parents. It is within the family that the child is first taught to know and worship God and to love his / her neighbor. Here the child experiences what it means to be a member of human society
