What It Is

What is a Independent Schools?

Independent schools are a category of private school that are nonprofit and governed by their own board of trustees, funded through tuition, endowment, and donations. They are "independent" of both the public system and (usually) any church or larger organization, setting their own mission, curriculum, and policies.

Where It Came From

History & origins

Many of America's oldest and most prestigious schools are independent, with roots stretching back centuries. The sector is represented by the National Association of Independent Schools (NAIS) and regional associations that set standards for governance and quality.

The Approach

Philosophy & approach

Independent schools emphasize self-governance, a distinctive educational mission, and accountability to families and their board rather than to a district or denomination. This independence lets them pursue particular academic, values-based, or pedagogical visions.

The Learning

Curriculum & academics

Independent schools are often known for academic rigor, small classes, and strong college preparation, with rich offerings in the arts, athletics, and extracurriculars. Many are day schools; some are boarding or both.

Inside the School

The classroom & school day

Hallmarks include low student-teacher ratios, well-resourced facilities, and a strong sense of community and tradition. Culture and rigor vary by school and mission.

Ages & Grades

Grade levels & structure

Independent schools span preschool through grade 12; some are elementary or secondary only, others full PreK–12.

Getting In

Admissions & enrollment

Admission is selective and application-based, commonly involving records, teacher recommendations, interviews, a student visit, and admissions testing (ISEE or SSAT). Selectivity ranges from accessible to highly competitive.

Paying for It

Costs & financial aid

Independent schools charge tuition, often among the higher private-school prices, but most offer substantial financial aid funded by endowment — so families should not rule them out on sticker price alone.

Oversight

Accreditation & governance

Independent schools are governed by a nonprofit board of trustees and typically accredited by a regional or state association and affiliated with NAIS, which signals adherence to standards of governance, ethics, and quality.

Is It Right?

Is a Independent Schools right for your child?

Independent schools suit families seeking rigor, small classes, strong college placement, and a distinctive mission, who can afford tuition or qualify for aid. They are worth exploring even for cost-conscious families, given the financial aid many provide.

How It Compares

How it compares to other schools

Independent schools are a subset of private schools — specifically the nonprofit, board-governed, non-religious ones. They differ from religious private schools (governed by a church) and from public charters/magnets (free and public).
