The first 5 years of your child's development can never be recaptured. Dr Maria Montessori coined the phrase the "Absorbent Mind" to describe the child's most crucial development stage: the first 6 years. Our infant-toddler classroom is staffed with an experienced Montessori-trained head teacher and infant-toddler certified assistants who are licensed by the Ma. Early Education Commission. Care is taken, as with all of our classrooms, to create a beautiful and engaging classroom environment that fosters the unique developmental needs of infants aged 3 to 15 months and toddlers aged 15 to 33 months. Between 33 and 36 months your toddler will be ready to transition into our Children's House program for ages 3 to 6. Please inquire for more information and to arrange a visit.

Why Kindergarten in Montessori? Our Full Day Kindergarten students received an enriching daily program, fully immersed in Montessori lessons in the morning with our mixed age classroom, followed with a focused afternoon work cycle. During the afternoon all of our 5 year olds come together to refine their academic skills through geography, handwriting, science, math, language; and also build self-confidence and independent research skills. They also have the opportunity to participate in our Health & Wellness program where they will enjoy on-site dance, karate, zumba, yoga ; and they also participate in off-site physical activities including tennis, skiing, and swim! Call us today at (978) 251 - 2929 to learn why our program is standards ahead of traditional education!

"If you want your child to be an independent problem-solver, critical thinker, then you need to discover Montessori, and more importantly discover Keystone. It has transformed our way of life and our view of our own children as these young, incredibly intelligent human beings who are capable of so much if given the proper support and means. Thank you Keystone for educating our children, who are educating us! This world would be a better place if there were more schools like this!" Read more...

“After looking around at other local day care centers and comparing prices, programs and teacher quality, I have to admit, I was a bit hesitant to spend the extra money on ‘Preschool’. After all, 3 year olds just like to color, right? Wrong. I took a leap of faith and enrolled my daughter at Keystone. For 2 years now she has been in the Children’s House full day program, and despite not really understanding how the full breadth of the Montessori philosophy at the time of enrollment, we couldn’t be more pleased with the outcome. She has shown me that 3 and 4 year olds are so much more capable then we give them credit for. " Read more...

Enrolling for January 2021! Due to Covid restrictions, we have reduced the size of our class rosters, going up to 10 students in each classroom for prek - K. We offer large, spacious classrooms allowing for freedom of movement & to support social distancing. Each child will be working with his/her individualized work space. We've also upgraded our HVAC unit with hospital grade filtration called needlepoint bipolar ionization, refreshing the air up to 6 times per hour. Available openings remain in our Prek-Kindergarten program, with very limited openings in our Infant-Toddler classroom & our Elementary classrooms. Call us at (978) 251 - 2929 or submit an inquiry below to learn more. A Montessori education is the best start you can provide for your growing child! Even more importantly, during these uncertain times, finding a quality school that supports the entire needs of your child (including social & emotional), while also addressing health & safety are paramount. Come see what makes Keystone so special and essential for your child during these times.

Boston Museum of Science Teams up with Keystone. What’s all this talk about STEM?  Education is catching on to what Montessori education has been doing for years. A couple of years ago, the Boston MOS filmed and documented our EL curriculum, as a model for other schools.
