MS LAM MONTESSORI SCHOOL

Families committed to both authentic Montessori and full Mandarin immersion, with a child up through grade 5, who want a small, philosophy-driven school and are comfortable planning ahead for middle school.

• Full Mandarin immersion wrapped around a classical Montessori framework, not a watered-down "Mandarin enrichment" bolted onto a mainstream curriculum.
• The four classic Montessori curriculum areas — Practical Life, Sensorial, Language, and Math — are explicitly named, signaling adherence to the original Montessori design rather than a hybrid.
• Three age-staged programs (Toddler, Primary 3–6, Elementary 6–11) with mixed-age classrooms within each stage, the hallmark of authentic Montessori grouping.
• Founder-led school bearing Ms. Lam's name, which parents often read as a sign of direct accountability and a single, consistent educational vision.
• An after-school program on site, useful for working families who need coverage past dismissal.

• Tuition is roughly $41,000 for 2025–2026 — at the higher end for an early-childhood Montessori, which is worth weighing against dual-language value and class size.
• The rooftop outdoor space is, by parent accounts, small — so most "outdoor" time depends on neighborhood sidewalks and nearby parks rather than a school yard.
• The program tops out at grade 5, so families will need to plan a middle-school transition (and that transition is the moment when full Mandarin immersion typically ends).
• Williamsburg waterfront commutes can be slow even with the L nearby; the nearest stations are walks, not right at the door.
• Because the school is small and language-specific, the social and cultural fit needs to be a deliberate family choice — a child with no Mandarin exposure at home is starting from a fully-immersed position, which is the point, but worth walking in with eyes open.
