The school becomes an accredited member of the accrediting group and is entitled to advertise as an accredited school. All accredited schools are not equally good. A school must be a good school to meet the minimum standards for accreditation. Schools may exceed those standards by varying degrees. Any accredited school, then, is considered a good school.
Some accredited schools are better than minimal and are superior schools.
Still other accredited schools are even better and are schools of distinction. Accrediting organizations do not designate schools as good, superior, or distinctive. They simply grant accreditation to, schools which have met their minimal standards, but it is obvious that some accredited schools are better than other accredited schools. No accredited school is perfect. Accreditation is valuable for many reasons, some of which are now given.
