Prince George’s County Schools Chief Executive Officer Kevin M. Maxwell was named the 2014 Educator of the Year by the Chesapeake Bay Foundation for his work in promoting environmental education in Maryland.

Maxwell co-chaired a state workgroup that was created to look at the integration of environmental education from kindergarten through 12th grade. The workgroup recommended that the state adopt environmental literacy as a graduation requirement and the state Board of Education approved the recommendation, making Maryland the first state in the country to adopt the graduation requirement.

Will Baker, president of the foundation, called Maxwell a “tireless champion” of environmental education.

“He knows what hundreds of classroom teachers and building principals have discovered in Maryland — students learn outside,” Baker said in a statement.

Last year, Maxwell was named the 2014 Maryland Superintendent of the Year for his work as the Anne Arundel County Schools Superintendent. He was also one of four finalists for the national award.
