Catholic schools are pre-primary, primary and secondary educational institutions administered in association with the Catholic Church. , the Catholic Church operates the world's largest religious, non-governmental school system. In 2016, the church supported 43,800 secondary schools and 95,200 primary schools. The schools include religious education alongside secular subjects in their curriculum.
Across Europe, North America, Australia and New Zealand, the main historical driver for the establishment of Catholic schools was Irish immigration. Historically, the establishment of Catholic schools in Europe encountered various struggles following the creation of the Church of England in the Elizabethan Religious settlements of 1558–63. Anti-Catholicism in this period encouraged Catholics to create modern Catholic education systems to preserve their traditions. The Relief Acts of 1782 and the Catholic Emancipation Act of 1829 later increased the possibility to practice Catholic Christianity in England openly and to create charitable institutions by the Church. This led to the development of numerous native religious congregations which established schools, hospitals, orphanages, reformatories, and workhouses.
Catholic schools are distinct from their public school counterparts in focusing on the development of individuals as practitioners of the Christian faith. The leaders, teachers, and students must focus on four fundamental rules initiated by the Church and school. This includes the Catholic identity of the school, education in regards to life and faith, the celebration of life and faith, and action and social equality.
Like other Christian-affiliated institutions, Catholic schools are generally nondenominational, in that they accept anyone regardless of religion or denominational affiliation, sex, race or ethnicity, or nationality, provided the admission or enrollment requirements and legal documents are submitted, and rules & regulations are obeyed for a fruitful school life.
