What this specialty covers
A behavior analyst is qualified by at least a master's degree and Behavior Analyst Certification Board certification and/or a state-issued credential (such as a license) to practice behavior analysis independently. Behavior analysts provide the required supervision to assistant behavior analysts and behavior technicians. A behavior analyst delivers services consistent with the dimensions of applied behavior analysis. Common services may include, but are not limited to, conducting behavioral assessments, analyzing data, writing and revising behavior-analytic treatment plans, training others to implement components of treatment plans, and overseeing implementation of treatment plans.
Reading the sole-proprietor share
For this specialty, the sole-proprietor flag can help describe how many NPI records identify an individual business structure, but it should not be read as a count of behavior analysts working in private practice. It is a self-reported NPPES field and may not capture employed clinicians, group arrangements, or other practice relationships, so the share is an imperfect proxy.

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 may represent an individual provider or an organization, so the active-record total may not equal the number of unique behavior analysts or currently practicing clinicians.
- - The primary taxonomy is an NPPES classification and may be updated over time; it does not by itself verify credentials, services, or current clinical activity.
- Providers are counted once, by their primary taxonomy code only.
