All religious and independent schools have a responsibility to provide their students with the knowledge, skills, and values they need to succeed in life and to contribute to the common good. Schools employ a variety of means to demonstrate, both to the families and communities that support them and to the public at large, that they live up to that responsibility. Many schools use accreditation to review and evaluate all aspects of their institutions, to identify successes as well as areas for improvement, and to remain accountable to parents and the public.
