The Manor Montessori school, with locations in Potomac, Rockville and at St. Dunstan's Episcopal Church in Bethesda, was founded in 1962. The St. Dunstan's location serves children from ages two to nine, with a half-day program provided for two-year-olds. As at other Montessori schools, children at The Manor are encouraged to work independently under a teacher's supervision, with an emphasis on hands-on learning. Accredited elementary education is also available through the third grade.
