California recorded 1,651 providers in the latest CMS NPI registry weekly update, representing 16% of the national weekly total. The registry includes 968 new providers this week, with 1,537 individuals and 114 organizations. That concentration underscores California’s scale as a behavioral health market and suggests that provider activity there can materially influence national workforce and access trends. NPI records do not, however, confirm active caseloads, employment relationships or available appointment capacity.

ABA Workforce Mix

The credential data lists 52 BCBA credentials and 714 RBT credentials, including 10 dual credentials held by providers identified as both BCBA and RBT. These categories overlap and are not mutually exclusive shares of the provider total; credential fields and taxonomy fields can describe the same provider in different ways. The large gap between RBTs and BCBAs points to a workforce weighted toward direct service delivery. Because BCBAs supervise RBTs, design treatment programs and oversee clinical quality, the relatively smaller BCBA pool may limit how quickly clinics can expand services, even when technician recruitment is strong. The dual-credential count indicates some career progression between technician and analyst roles, but it remains limited in this update.

Demographics and Organizations

Gender records identify 1,127 female providers, 290 male providers and 120 nonbinary providers, corresponding to 73%, 19% and 8%. The leading cities listed are Los Angeles, San Diego, Colton, Sacramento and Monrovia, showing activity across major metropolitan areas and inland communities. Momentum for Health appears nine times, while Olive Crest appears twice. Repeated organizational entries reflect separate NPI records and should not be read as equivalent to nine or two distinct employers, sites or service teams.

California’s strong RBT presence signals continued frontline ABA workforce growth, while the smaller BCBA pool makes supervisory capacity a key determinant of future access.
