Washington recorded 282 providers in the latest CMS NPI registry weekly update, equal to 3% of the national weekly total. The file includes 129 providers added this week and 156 added this year. That concentration signals a sizable presence in the national registry, but NPI records track enrollment activity, not confirmed hiring, staffing levels or appointment availability.

ABA workforce mix

The credential summary lists 17 BCBAs and 57 RBTs, plus 3 providers with dual BCBA-RBT credentials. These counts overlap: dual-credential providers may also appear in the BCBA and RBT counts, so the categories are not separate workforce shares. The larger RBT count points to a technician-heavy profile, while the smaller BCBA count highlights the importance of supervisory capacity as direct-service staffing grows. The file also reports 61 providers with multiple taxonomies, another reason not to treat classifications as mutually exclusive. Its separate credential-text summary uses a different presentation and should not be read as a complete workforce census.

Demographics and organizations

Women account for 175 providers (72%), men for 48 (20%) and nonbinary providers for 19 (8%). Those figures describe the full provider file, not ABA staff alone. The registry identifies ILLAHEE HOME CORP and EVERSIDE HEALTH, LLC twice each among notable organizations; repeated records do not necessarily represent distinct employers. Seattle, Spokane, Vancouver, Bellevue and Tacoma are the leading listed cities, indicating activity across several urban centers.

Overall, the update suggests Washington’s ABA workforce includes more registered technicians than BCBAs, making BCBA recruitment and retention important to sustaining supervision and expanding access.
