Let the school know you're thinking of applying — they can share their prerequisites and help you through the process.
It's best to ask — circumstances can change at any time.
The 2026-2027 Admission Cycle began in October 2025. Contact LMS for information at 781-862-8571 or inquire online. Campus tours are hosted every fall for prospective parents, and campus tours can be scheduled after submitting an inquiry. After touring, complete an admission application; other forms may be required depending on the age of the applicant, including student evaluation forms from the current teacher, report cards, and, for middle school applicants, an essay. Downloadable forms include AISNE Release Form, AISNE Form for Pre-K–1st Grade, AISNE Form for Grades 2–5, AISNE English Form for Grades 6–12, AISNE Math Form for Grades 6–12, Toddler Program Applicants' Teacher Evaluation, and Essay Question for Middle School Applicants. Meet with the Director of Enrollment after your completed application; the interview usually lasts about an hour and attended by parents. Schedule a visit and assessment for your child: toddlers participate in a visit; Children's House applicants may have admission videos; Kindergarten through Upper Elementary visit in person for their assessment; third through sixth grade applicants experience the rhythm of the school day, and middle school applicants typically visit for a full day with an academic assessment.
Financial aid at LMS provides need-based aid to families who might not otherwise be able to attend LMS. To apply for financial aid, fill out the Clarity application by January 31, 2026 (this does not replace the admission application, but is an additional step). You will be notified of your qualification with your admission decision. For more information, consult our Financial Aid Guidelines and Policies or contact Aimee Randall, Director of Enrollment.
Lexington Montessori School is an independent day school serving children from 21 months to 14 years. It delivers Montessori pedagogy in classrooms guided by certified Montessori educators, with students learning through self-discovery. The curriculum spans Practical Life, Sensorial, Math, Language and Cultural Studies, and integrates anti-bias education across all learning. In addition to core Montessori work, students participate in art, farming, library, music, physical education and a Spanish language program. The campus hosts METTC, the Montessori Elementary Teacher Training Collaborative, on site for eight weeks each summer, and Horizons@LMS as a Horizons National affiliate. The community emphasizes outdoor learning, Diversity, Equity, Inclusion and Belonging, and maintains small class sizes with an average 6:1 ratio. The 23-acre campus includes 19 acres acquired in 2018 with woods, streams and wetlands, plus an A-Frame meeting space, a greenhouse and a farming program. Outdoor field studies and service projects broaden civic awareness and environmental stewardship.
