What the code means
An assistant behavior analyst is qualified by Behavior Analyst Certification Board certification and/or a state-issued license or credential in behavior analysis to practice under the supervision of an appropriately credentialed professional behavior analyst. An assistant behavior analyst delivers services consistent with the dimensions of applied behavior analysis and supervision requirements defined in state laws or regulations and/or national certification standards. Common services may include, but are not limited to, conducting behavioral assessments, analyzing data, writing behavior-analytic treatment plans, training and supervising others in implementation of components of treatment plans, and direct 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
9,640 of these are people and 107 are organisations, so 1% of the code is businesses rather than clinicians. Half of them had registered by 2022, and 6,365 registered in the last five years, 65% of the current population.
That is a fast-growing code. A population where a large share registered recently is either a genuinely expanding field or a category NPPES added late, and the taxonomy definition above usually tells you which.
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.

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.
