Arizona recorded 178 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. With 80 new providers added this week, the state’s activity signals continued behavioral health expansion, although the national concentration remains distributed across a broad provider market.

ABA Workforce Dynamics

The registry lists 15 BCBA credentials and 43 RBT credentials, plus 1 dual BCBA-RBT credential. These categories overlap with broader taxonomy and credential fields, so they should not be treated as mutually exclusive shares of Arizona’s provider total. The RBT-to-BCBA balance points to a larger direct-service workforce than supervisory workforce. Because BCBAs supervise RBTs and oversee treatment planning, that structure can support service delivery but may also leave supervisory capacity as a constraint as the technician workforce grows. Several additional records use credentials that include BCBA, such as “M.S.W., B.C.B.A.” and “MED, BCBA, LBA,” reinforcing the need to interpret registry labels carefully.

Workforce Profile

Of the individual providers, 101 women represented 75%, while 29 men represented 21% and 5 nonbinary providers represented 4%. No notable organization appeared multiple times in the update. Providers were concentrated in Phoenix, Tucson, Gilbert, Mesa and Scottsdale, but records also extended to rural and tribal communities, including Yuma, Winslow, Sacaton and Kayenta.

Arizona’s strong weekly additions, technician-heavy ABA mix and broad geographic footprint suggest expanding access, while the comparatively smaller BCBA pool underscores the importance of developing supervisory capacity alongside frontline hiring.
