School Social Worker: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this School Social Worker classification, the sole-proprietor share describes NPPES records with that status, not the number of providers who operate a private practice. The field is self-reported: 2,196 records, or 33.1%, are flagged as sole proprietors. It is an imperfect proxy because the flag does not by itself establish a provider's practice setting or business arrangement.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• - These figures count active NPI records using School Social Worker as the primary taxonomy, not every provider who may perform school social work.
• - An NPI record is not necessarily a direct measure of a unique person, practice location, or full-time-equivalent clinician.
• - The year of first enumeration indicates when an NPI was assigned, not necessarily when the provider began practicing in this specialty.
• Providers are counted once, by their primary taxonomy code only.
