Washington added 232 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. With 104 new providers recorded this week, the state’s activity signals a meaningful, though not dominant, contribution to national behavioral health workforce growth.

ABA Workforce Dynamics

The registry lists 4 BCBA credentials and 39 RBT credentials, with no dual BCBA-RBT credentials reported. These credential counts overlap with taxonomy and other credential fields, so they should not be read as mutually exclusive shares of Washington’s provider total. The roughly ten-to-one RBT-to-BCBA count points to a direct-service-heavy ABA workforce and limited documented supervisory capacity. Because BCBAs design treatment plans and supervise RBTs, that imbalance can constrain how quickly clinics expand caseloads unless additional supervisors are available outside this weekly registry count.

Workforce Profile

Individuals accounted for 204 providers, compared with 28 organizations. The gender breakdown was 159 female providers (78%), 35 male providers (17%), and 10 nonbinary providers (5%). The credential mix also extends well beyond ABA: LMHCA appeared 11 times, while LMHC, LCSW and LICSW each appeared 4 times in the summarized credential text. No organization appeared multiple times among the notable organizations, although the registry includes providers across Seattle, Tacoma, Spokane, Bellevue and Vancouver.

Washington’s strong weekly intake, combined with many RBT records but few documented BCBAs, suggests expanding frontline ABA capacity that may face supervisory bottlenecks as access grows.
