Reading the sole-proprietor share
For this specialty, 3,892 of 10,274 active records, or 37.9%, carry that flag, so it answers a narrow question about how many records are marked as sole proprietors. The field is self-reported in NPPES and is an imperfect proxy for private practice: it does not by itself establish employment setting, ownership, independence, or whether a nurse works in a school or another arrangement.

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.
- An NPI count is a count of active records, not a count of nurses, jobs, school programs, or patient capacity.
- NUCC publishes no official definition for this taxonomy, so the classification may not capture every provider performing school nursing or every related role.
- Enumeration-year totals show when NPIs were first enumerated, not necessarily when providers began practicing or entered a particular employment arrangement.
- Providers are counted once, by their primary taxonomy code only.
