If you’re in the vicinity of a major U.S. city, you’ve probably heard about its elite private schools. For many families, they have to consider whether they choose to go public or private. If they choose the latter, what type of private school makes the perfect fit?
Boarding schools can be a good fit for some students. However, most families prefer a day school model where students return home daily, stay connected to siblings and local activities, and remain rooted in their community.
In this guide, we want to highlight 12 prominent private day schools in four areas:
- New York City
- Greater Boston

What To Do Next?
Seeing these prestigious school names all in one place can feel intimidating with a hint of excitement. These are schools with long histories, established reputations, and very competitive admissions. However, the elephant in the room is not “Which school looks most impressive on paper?” Rather, it is “Where will my child grow, stay healthy, and actually enjoy learning every day?”
This list is meant to be a starting point, not a finish line. Each school has a distinct culture: single sex or coed, one-on-one or seminar types, traditional versus progressive, humanities or STEM focused, city-centered or suburban? As you explore your options, look beyond rankings and college rankings. Pay attention to class size, teaching style, workload, stress level, commute, and their level of emotional quotient.
