Private schools can also be divided into two groups. Religion-based systems of education are operated by the Anglican, Lutheran, Roman Catholic denominations as well as a number of other church or parachurch-based low-fee schools. By far the most numerous are Catholic schools, which are run by diocese-based educational institutions within the Catholic Church called the Catholic Education/Schools Offices,[2] although some more prestigious Catholic schools are independent. The rest are known as independent schools, which are largely Protestant grammar schools. There are also a few Jewish and Islamic schools, and a growing number of independent Montessori and Steiner schools.
