What the code means

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.

Where they are

Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Who registers under this code

108,001 of these are people and 17,102 are organisations, so 14% of the code is businesses rather than clinicians. Half of them had registered by 2019, and 49,613 registered in the last five years, 40% of the current population.

That is close to the pace of the registry as a whole.

Where the practices are

By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

What else they list

Providers whose primary code is Behavior Analyst most often carry these secondary taxonomies as well. This is the closest thing the registry has to a map of which specialties overlap in practice, and it is not published anywhere else.

Looking up a specific provider

These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
