Financial District
The Financial District is Manhattan's historic tip — dense skyscrapers and the columns of Wall Street, now a fast-growing residential neighborhood with harbor access, waterfront esplanades, and some of the city's best transit convergence.
Overview
Pine Street School is a Financial District independent school running from age one through Grade 8. Academically it's an International Baccalaureate school (Primary Years Programme), with early-childhood classrooms the school describes as Montessori-influenced. It's part of Green Ivy Schools, a for-profit operator (the same group behind Battery Park Montessori), and offers a trilingual environment with Spanish and Mandarin.
Programs & ages
Toddler and early-childhood classes flow into an IB Primary Years elementary and on through middle school (Grade 8) — one of the few downtown options that continues in-house that far, with language immersion throughout.

Accreditation & authenticity
This is the key nuance: Pine Street is an IB school, not an AMS/AMI-accredited Montessori. Its early years borrow from Montessori, but the through-line is the IB framework. If authentic Montessori is your priority, weigh that carefully — see our authenticity guide.
What parents say
Independent review volume is limited. The draw is a trilingual, IB continuum from toddlerhood through middle school in a convenient downtown location; the trade-off for Montessori purists is the IB (not accredited-Montessori) identity.
