Our model

Acorn Montessori School is an early childhood, independent Montessori School for children ages 15 months through age 12. We are affiliated with the American Montessori Society, and a member of the New Jersey Montessori Administrators Council.

Acorn has assembled a dedicated Montessori faculty balanced by academic, art, music, foreign language, yoga/mindfulness and education specialists and professionals. Each classroom is led by a Montessori-certified teacher, supported by assistant teachers.

Our Elementary students may continue their education at public or private schools, assured of well-rounded and developed study skills and knowledge. Students leave Acorn with a sense of self-confidence and comfort in tackling a new environment and expectations.

Our history

On September 5, 1984, Acorn Montessori School welcomed ten eager children into their carefully prepared classroom, the Fellowship Hall at the Allerton Methodist Church. Clinton Township Mayor Ted Savage attended the opening day ceremony, planting an oak tree to symbolize how little acorn seeds grow into strong and glorious oaks. By the end of the first year, there were 24 children, ages three to six in the class.

Enrollment reached fifty by the end of the second year, and Acorn moved south on Route 31 to the Karma Restaurant building, formerly a farmer’s home that had been displaced by Round Valley Reservoir. After a summer of scrubbing, painting and ordering new furniture and materials, Black Oak and Golden Oak were ready in the fall of 1985. As enrollment increased, new classrooms were added, White Oak in 1990 and Red Oak in 1991.

In September 1994, ten dogwoods were planted to celebrate our tenth anniversary along with a ribbon cutting ceremony to inaugurate the new Toddler House and Enrichment Barn (Greenhouse). At that time, Acorn had a staff of 20 and 154 children. In September 1999, Acorn grew to include the Great Oaks Elementary Class.

Over the years, Acorn Montessori School has strived to develop in each of its students a love of learning and to create an environment that nurtures the child at a time in their young lives when he or she absorbs knowledge naturally and enthusiastically.
