Twin Parks runs three AMS-accredited Montessori campuses on the Upper West Side — Central Park, Park West and Riverside — each serving roughly three months through age six. All three disclose their staff and credentials (our highest transparency rating), and two offer free NYC Pre-K seats.
Headline tuition is the comparable full-day early-childhood (3–6) rate for 2026–27; confirm the exact figure and schedule with each campus.
| Campus | Neighborhood | Ages | Tuition 2026–27 | Notable |
|---|---|---|---|---|
| Park West | UWS · Central Park West | 3 mo–6 | $27,180 | Lowest price of the three; Columbia-affiliated; offers free Pre-K for All seats |
| Riverside | UWS · Riverside Dr | 3 mo–6 | $32,360 | Riverside Park campus; offers free Pre-K for All seats |
| Central Park | UWS · at Central Park | 3 mo–6 | $33,960 | Daily Central Park time |
All three are AMS-accredited (a formal review against AMS standards, not just membership), run infant/toddler through primary (3–6) Montessori, and earn a green staff-transparency rating on this site for publishing who teaches and their credentials. Park West and Riverside participate in NYC's free Pre-K for All, so a 4-year-old's year can be tuition-free at those campuses — see our free 3-K & Pre-K guide.
The programs are closely aligned; the practical differences are location, price and outdoor access. Park West is the most affordable and Columbia-affiliated; Riverside sits by Riverside Park; Central Park builds in daily park time. Tour the specific campus you'd enroll in and confirm current tuition and free-seat availability for your child's year.
