Arizona had 151 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. That share signals a modest portion of nationwide registry activity, not a measure of Arizona’s full workforce or service capacity. The update includes 55 new providers this week and 67 this year. It lists 109 individuals and 42 organizations, which together make up the state’s provider total.

ABA Workforce Mix

The credential summary reports 14 BCBAs, 31 RBTs and one provider with dual BCBA-RBT credentials. These categories overlap: the dual-credential provider may be included in both credential totals, so they should not be added as separate workforce groups. RBTs outnumber BCBAs, a pattern consistent with a technician-heavy service model. But BCBAs supervise RBTs, and the relatively smaller BCBA count points to a potential constraint on supervision capacity as technician participation grows. The registry also identifies 34 providers with multiple taxonomies, another reason not to treat classifications as mutually exclusive.

Demographics and Organizations

The listed population includes 89 women, or 82%; 18 men, or 17%; and two nonbinary providers, or 2%. The rounded percentages sum to more than 100%, and these demographics cover all listed providers, not only ABA professionals. TERROS appears repeatedly: the notable-organizations field reports six records under “TERROS, INC.” and two under “TERROS INC,” name variants that may refer to the same organization. NAZCARE and SABA Integrated Behavioral Health Services each appear three times. Phoenix, Mesa and Tucson are among the leading listed cities.

Arizona’s update shows more RBT than BCBA records, suggesting that ABA access will depend on whether supervisory capacity keeps pace with the technician workforce.
