The Middle States Association Commissions on Elementary and Secondary Schools (MSA-CESS) announced today the appointment of John J. D’Adamo, Head of the Middle and Upper School at York Country Day School in York, Pa.
D’Adamo is one of 11 new commissioners.
“Middle States commissioners serve an important role in helping to improve the quality of education in the United States and around the world,” said MSA-CESS Interim President Henry Cram, Ed.D. “We are grateful to John for his commitment to Middle States and look forward to his continued contributions to helping schools grow and improve through accreditation.” 
Prior to his role at York Country Day School, D’Adamo served as principal for multiple schools in the Archdiocese of Baltimore for more than a decade. He brings extensive experience in instructional leadership, institutional advancement, and professional leadership, and has participated in and chaired several peer review teams for Middle States.
D’Adamo has a Master of Science in education from Johns Hopkins University, a Master of Arts in liberal studies from Loyola University Maryland and a Bachelor of Arts in English education from Mount Saint Mary’s University.
“The Middle States accreditation process is one of the most effective tools for improving student outcomes and advancing academic excellence,” said D’Adamo, who lives in Jarrettsville, Md. “I am honored to join Middle States as a Commissioner and to have the opportunity to help ensure all students have access to a quality education.”
Commissioners meet twice annually to review accreditation recommendations and the organization’s finances, policies and strategic plan.
