The Best Private Schools in America

Private schools have played a very important role in American education historically, a tradition that continues today for parents who want their children to have a stellar education with very good collegiate prospects to the best colleges in the nation.

Private schools come in two varieties: those with and those without boarding facilities.

This article ranks the best Private Schools in America, which include boarding and day schools.

This article was first written in 2014, and relied on data from 2013 or 2014 that was available, such as tuition rates.

While making this update, we've calculated the tuition increase since 2014. Many of these schools have increased their tuition 40% - 50% since 2014.

Private schools without boarding facilities are called day schools, given that the students only attend during the day.

Students who attend private schools can receive first-rate academic instruction and develop valuable social and personal skills through social clubs and the like. Many students from these schools go on to attend many of the best colleges in America.

As with all of the ranking articles on SuccessfulStudent.org, this ranking is considered from the students' point of view, and takes into consideration academic excellence, academic and student diversity, student development, collegiate prospects, and cost.

Academic Excellence. To prepare students academically for their years of college, private schools need to have top tier academics. Good private schools make the transition to college as seamless as is possible. The quality and expertise of the faculty is very important, and one arbiter of this is the faculty that holds advanced degrees.

Academic and Student Diversity. Academics shouldn't be an echo chamber, nor should the student body necessarily be homogenous. In modern society our world is more interconnected than ever before, and economics are becoming increasingly interdependent. The business world and the marketplace of ideas are wide and varied, and those students who can approach them with a wide and varied academic training and backdrop of diversity are best suited for producing successful endeavors. The roots should begin in grade school and be further developed in college as the complexities of the world are explored.

Student Development. Being a successful student doesn't stop with grades, it includes growing in personal and interpersonal relationship skills and social awareness. Good private schools will nurture this environment, and encourage academic awards and honors programs, as well as sponsor extracurricular activities, participation in student groups and internships. An important factor is preparing students for the competitive, yet cooperative environment in the college setting.

Collegiate Prospects. Getting into a good college is often paramount to students and their parents. It is important that private schools maintain an ongoing relationship with reputable colleges and pipeline their students to them. Parents will intentionally send their children to private schools such as these in our list, so that they can attend prestigious universities.

Cost. There are cost factors to be considered by parents who've decided to send their children to private school, such total tuition and financial aid. Many private schools will provide significant financial aid to the admitted students who qualify, and financial aid is usually need based.

A private school education shouldn't be excluded from bright students because of tuition costs, and many schools attribute significant amounts of financial aid for those families who can demonstrate their need, thus making private school affordable. In some cases at some schools tuition is fully covered by grants (if the parents qualify).

This spirit lives on in more than just the Laboratory School's name. The high school's resources are integrated into the larger, nearly 7 billion dollar University of Chicago.

This gives the day school unmatched resources that dwarf its competition. It also gets students in the laboratory early and often, which prepares them to hit the ground running after graduation at another major research university. While other schools pride themselves on offering many languages or art programs, Lab's students are thought to use university libraries as they study the natural world with a hands on approach.

Tuition is $18,546 for half day nursery school through $29,424 for full time high school.
