A warm, small school, but it presents as Montessori-inspired and its credentials aren't fully documented — ask what Montessori training the teachers hold and whether the program is AMS/AMI affiliated. Why this matters →


Park Slope is the quintessential family neighborhood — tree-lined blocks of brownstones with stoops, a strong stroller-and-playground culture, and Prospect Park on its doorstep, served by the F/G and 2/3.
Little Thinkers Montessori is a small, independent early-childhood school founded in 2012 in Park Slope, serving children from 12 months through Pre-K. It presents as Montessori-inspired, and — helpfully for local families — participates in NYC's free Pre-K for All.
Toddler through Pre-K in an intimate setting. Because it ends at Pre-K, families plan a kindergarten move afterward (public, charter or private).
Private tuition is provided on request. Importantly, the school offers free Pre-K for All seats, so eligible four-year-olds can attend at no cost via MySchools. See our free 3-K & Pre-K guide.
As a small owner-run school, named staff and their Montessori training aren't fully published. Ask who leads each classroom and what certification they hold.
Little Thinkers describes itself as Montessori-inspired rather than an accredited Montessori, and we couldn't verify AMS/AMI affiliation — so treat the "Montessori" label accordingly. Our authenticity guide covers what to ask.
Independent review volume is limited; the appeal is a warm, small program in a family-dense neighborhood with a free Pre-K option. Weigh a tour heavily.
Signals from public parent forums and listservs (Park Slope Parents is the key local source). Forum chatter is opinion — take it with a grain of salt.
Inquire and tour directly for private spots; for the free Pre-K seats, apply through the DOE's MySchools process on the city's timeline. Our admissions timeline and planner help you track both.
