Underscoring its commitment to excellence in education, Wilmington Montessori School (WMS) was reaccredited by both the American Montessori Society (AMS) and the Middle States Association of Colleges and Schools for a seven-year term ending May 1, 2025, for upholding to the highest standards of Montessori education.

Every seven years, representatives from AMS visit WMS to closely examine the school's practices and determine whether it meets the standards to be accredited for another term. During the reaccreditation process, all aspects of the school are examined, including governance, curriculum, fiscal and personnel policies, facilities, health and safety practices, teacher preparation and learner outcomes. The AMS review team also evaluates the school to see how well it is achieving its own mission and goals.

After the evaluation process is completed, the school commits to a plan that incorporates the AMS review team's recommendations. All AMS-accredited schools must comply with school accreditation standards and work toward continuous improvement. Each year, accredited schools must submit a report that outlines their progress toward their strategic plan objectives.

In its final report, the visiting AMS team shared commendations and recommendations, which let WMS know what it does well and what it can improve. The strengths AMS noted at WMS included: 

• The relationships between students, teachers, parents and other community members -  the way in which we all work together to encourage and support autonomy and independence in the children.
• Our teaching practice, our care for the social and emotional well-being of the children, and our engagement with each other as a strong community.

As part of a cooperative accreditation effort between AMS and Middle States, WMS also received reaccreditation from Middle States, which accepted AMS's accreditation maintenance requirements as fulfilling its own requirements.
