Raritan Valley Montessori was founded as a Montessori school in 1967 in the South Branch section of Hillsborough, New Jersey. It is one of the oldest Montessori schools in New Jersey and one of the older ones in the United States. The original name was The Carroll School. In 1969, the school changed ownership from a private individual to a parent cooperative and was renamed Raritan Valley Montessori School. In June of 1984, the school was sold to Leslie S. Meldrum, once again becoming a private corporation. In September of 1997, the Elementary program moved to Bridgewater and became a non-profit school, Raritan Valley Montessori Academy. In September of 1998, 2 more classrooms opened and in the fall of 2009 we added a Stepping Stones program at the Academy. Raritan Valley now has programs for children aged 16 months – 12 years (6th grade).
Raritan Valley Montessori Academy is affiliated with The Cherry Blossom Montessori School located in Hillsborough, New Jersey.
