Middle States Commission on Elementary Schools  Even sixty years ago when I was in high school, the three-day visit of a Middle States evaluation team was a big deal. Later, I learned that preparation for these visits involved many meetings, much paperwork, many questions. The important thing for Catholic schools was that the Middle States first asked the goals of the institution, then inspected it as meeting these goals, then offered suggestions for improvement. It was and is possible to have accreditation suspended. Please note that accreditation on the K-12 level is probably very different from the accreditation of colleges and universities.
