In the fall of 1995 St. Clement School received its reaccreditation from Middle States based on a project that infused multiculturalism into the existing curriculum.
In May 1999, as part of its five year post reaccreditation update, St. Clement M.H. School created a website for the Middle States Online Descriptions of Accredited Schools.
In 2005 St. Clement School received another reaccreditation from Middle States based on a self-study and action plan.
