Washington recorded 307 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The registry added 107 new providers this week, giving Washington a substantial presence in nationwide behavioral health activity. That concentration signals an active and expanding provider market, although the registry includes multiple behavioral health disciplines and does not measure service capacity or patient access directly.

ABA Workforce Mix

Washington’s registry includes 16 BCBA credentials and 45 RBT credentials, along with 2 dual credentials held by providers listed as both BCBA and RBT. These categories overlap and are not mutually exclusive shares of the state’s provider total; credential and taxonomy fields can capture the same provider more than once. The pattern still points to a much larger direct-service RBT workforce than supervisory BCBA workforce. Because BCBAs oversee RBTs, treatment planning and clinical quality, the ratio suggests that supervision capacity could constrain how quickly ABA organizations convert workforce growth into additional treatment slots.

Demographics and Provider Activity

The update lists 268 individuals and 39 organizations. Gender data identifies 202 female providers, 53 male providers and 13 nonbinary providers, corresponding to 75%, 20% and 5%. Those gender counts should be read as a demographic subset rather than a complete description of every registry entry. Seattle, Vancouver, Spokane, Kent and Olympia are the leading cities listed for activity.

Children's Home Society of Washington appears 4 times among notable organizations, while Inland Virtual Counseling PLLC appears 2 times. The combination of broad provider growth, strong RBT representation and fewer BCBAs suggests Washington’s ABA access may expand, but supervisory depth will remain central to workforce planning.
