Private Schools List: Campuses, Dioceses and Trading Names

A usable private schools list is free: NCES publishes the national universe with filters for affiliation, grade span and state. The hard part is not finding schools, it is working out whether the campus, the diocese or a management organisation actually signs the contract.

Education is one of the better-documented markets in this series, and it still breaks generic prospect data, because the entity that appears in a business database is often the owning organisation rather than the school you want to reach.

How many private schools are there in the US?

NCES published the current figures in 2026, describing the 2023-24 school year. There were 30,553 US private schools, enrolling 5,096,365 students and employing 517,780 full-time-equivalent teachers.

Affiliation dominates the shape of this market: 6,228 Roman Catholic private schools served 1,715,733 students in that year. Roughly one in five private schools, and one in three private-school students, sits inside a single affiliation with its own purchasing conventions.

Note the vintage carefully when you quote these. The figures describe schools operating during the 2023-24 school year and the report was published in 2026, which is the most recent complete picture rather than a stale one.

For current industry context, private educational-services establishments numbered 173,246 in the first quarter of 2026, preliminary, with educational-services employment at 4,049.7 thousand in July 2026, preliminary. That is the whole NAICS 61 sector, including tutoring, training and higher education, so it is context rather than a school count.

Where the official list actually is

NCES is the national starting point, and it is better than most paid alternatives. The Private School Locator can filter by religious affiliation, association membership, state, grade span, program emphasis and gender, and the underlying PSS data is downloadable.

States add depth where they collect it. Florida, for example, maintains a statewide Directory of Private Schools built from an annual survey that private schools are required to complete. Where a state mandates the survey, its directory is more current and more complete than any commercial file.

A workable sequence:

1. Pull the national universe from NCES and treat it as your account list.
2. Segment on affiliation first, because it predicts both the buying process and the budget more reliably than enrolment.
3. Layer state directories where the state requires reporting, which fills gaps and refreshes contacts.
4. Use enrolment bands rather than employee counts to size accounts, since staffing ratios are relatively fixed.
5. Record the campus, the owning organisation and any management organisation as three separate fields from the start.

Resolving campuses to their owning and purchasing organisations is the specific problem Causo's private school prospecting is built for.

Why generic databases miss private schools

They record the wrong entity. Generic databases frequently carry the legal nonprofit, diocese, foundation or parent organisation rather than the school's trading name, so your outreach reaches an administrative office instead of a campus.

Campus-level records go missing. A network operating twelve schools may appear as one record, hiding eleven buildings where the actual users work.

The qualifying attributes are absent: affiliation, grades served, enrolment, tuition and accreditation are what determine fit, and none are standard business-data fields.

And the term "private school" itself spans day schools, boarding schools, parochial schools, Montessori programmes and specialist provision, which have almost nothing in common commercially. The general failure of buying rows rather than qualifying them is covered in B2B prospecting for founders.

Selling software to private schools: who decides, and when

At an independent school, the head of school or principal decides, with a business manager or CFO involved once the amount is material. In diocesan and network schools, administrative and technology systems are often decided centrally while classroom tools stay with the campus, so establish which model applies before pitching anyone.

Two timing realities govern this market. Budgets are annual and tied to the academic calendar, so a decision missed in spring usually waits a full year rather than a quarter. And the summer is when implementation happens, which means the practical selling window closes well before the school year does. Plan the pipeline around the calendar rather than your own. If you are still choosing a vertical, how to find customers for your startup covers the sequencing.
