A Christian school is a school run on Christian principles or by a Christian organization.
The nature of Christian schools varies enormously from country to country, according to the religious, educational, and political cultures. In some countries, there is a strict separation of church and state, so all religious schools are private; in others, there is an established church whose teachings form an integral part of the state-operated educational system; in yet others, the state subsidizes religious schools of various denominations.
Traditionally, many Christian denominations have seen providing catechesis as a necessary part of the educational formation of children; the Emmanuel Association of Churches, a Methodist denomination in the conservative holiness movement teaches, for example:
To this end, Christian Churches have established schools around the world.
In the United States, religion is generally not taught by state-funded educational systems, though schools must allow students wanting to study religion to do so as an extracurricular activity, as they would with any other such activity.
Over 4 million students, about 1 child in 12, attend religious schools, most of them Christian.
There is great variety in the educational and religious philosophies of these schools, as might be expected from the large number of religious denominations in the United States.
