Who We Are

The Middle States Association is a worldwide leader in accreditation and school improvement. For over 125 years, Middle States has been helping school leaders establish and reach their goals, develop strategic plans, promote staff development and advance student achievement.
Historically, MSA-CESS has operated in the mid-Atlantic region (Delaware, Maryland, New Jersey, New York, Pennsylvania, and the District of Columbia); with its cooperative partners, it has expanded its scope to include schools and institutions seeking accreditation throughout the United States. The Commissions also award accreditation to member institutions in more than 100 countries around the world.
