The National Christian School Association is an educational association of 98 secondary schools in 26 states serving more than 30,000 students. Most NCSA schools are independent, governed by a self-perpetuating board. A few are a ministry of a particular congregation, children's home or university. All of the schools have a historical relationship with the churches from the Restoration movement and most have a tie to the Churches of Christ. Students of all faiths are welcome at member schools of the National Christian School Association.
