Children happily and eagerly learn both life skills and academics, show care and compassion for their peers and their environment, develop refined and coordinated manual dexterity and fine motor coordination, and have an accurate sense of their own abilities, giving them confidence. We make these claims about Montessori, because we know from over a hundred years of hands-on classroom experience that it works.

But many other educational methods make the same claims. In Montessori, we're proud to be able to back ours up. Here you will find links to some of the most accurate and up-to-date research conducted on the benefits of Montessori education. This list is by no means exhaustive. If you know of a study that should be included here, please feel free to contact us with that information.
