California recorded 1,430 providers in the latest CMS NPI registry weekly update, representing 16% of the national weekly total. The update includes 785 providers added this week and 857 added this year, with 1,352 individuals and 78 organizations. That concentration makes California the largest state-level presence in this snapshot and signals a substantial pipeline of behavioral health participation. NPI activity reflects registry records, however, not confirmed staffing, caseloads or appointment availability.

ABA Workforce Mix

The credential summary lists 79 BCBAs and 623 RBTs, along with 12 dual BCBA-RBT credentials. These categories overlap: dual-credential providers are included in the broader BCBA and RBT counts and should not be treated as separate, mutually exclusive groups. The pattern is strongly technician-heavy, with roughly eight RBT credentials for every BCBA credential. That can support direct-service capacity, but it also places pressure on the supervisory workforce. BCBAs are needed to design treatment, supervise RBTs and maintain clinical quality. The registry also identifies 286 providers with multiple taxonomies, another indication that these classifications overlap and do not map cleanly to staffing roles.

Demographics and Organizations

Gender data identifies 947 female providers, 285 male providers and 120 nonbinary providers, reported as 70%, 21% and 9%. The repeated organizational names include Telecare Corporation, listed 3 times, while IPW Licensed Clinical Social Worker, Professional Corporation; Catholic Charities of Santa Clara County; Bonita House, Inc.; and Turning Point Community Programs each appear 2 times. Los Angeles, San Diego, Sacramento, Concord and Fresno are the leading listed cities.

California’s update points to expanding ABA technician capacity, but the smaller BCBA pool makes supervisory recruitment a key constraint on broader access.
