In 2013, Undercroft Montessori School achieved the distinction of becoming the first accredited Montessori school in Oklahoma through both the American Montessori Society and AdvancEd. The two-year-long process leading to accreditation engaged the entire community of board, staff, parents and students and is a reflection of our commitment to excellence in Montessori education.
