We are an independent, non-profit, progressive, co-educational school located in Montclair, New Jersey. The school enrolls approximately 200 children from nursery through eighth grade. Founded in 1963, it is one of a handful of cooperative schools nationwide. The school is accredited by the New Jersey Association of Independent Schools.

At MCS, teachers, parents and administrators work together to create a rich and rewarding educational environment. Every child is known, respected, and nurtured. All of our students receive the support they need to flourish academically, socially, and creatively. Graduates of the Co-op succeed at the most rigorous private schools and highly rated public schools. By the time they graduate they are inspired learners who value intellectual curiosity. They care passionately about ideas and feel a sense of responsibility to the world and people around them.
