A parochial school is a school that provides religious education in addition to conventional education. In a narrower sense, a parochial school is a Christian grammar school or high school which is part of, and run by, a parish.

In British education, parish schools from the established church of the relevant constituent country formed the basis of the state-funded education system, and many schools retain a church connection while essentially providing secular education in accordance with standards set by the government of the country concerned. These are often primary schools, and may be designated as name C.E. School or name C.E. (Aided) School, depending on whether they are wholly or partly funded by the church (the latter is more common).

In 2002, Frank Dobson proposed an amendment to the Education Bill (for England & Wales) which would limit the selection rights of faith schools by requiring them to offer at least a quarter of places to children of another or no religion, in order to increase inclusivity and lessening social division. The proposal was defeated in Parliament.
