Massachusetts has 250 providers in the latest CMS NPI registry weekly update, accounting for 2% of the national weekly total. That share marks a measurable concentration of registry activity in the state, though NPI listings do not confirm employment, active caseloads or appointment availability. The update reports 145 new providers this week and 160 this year; 222 are individuals and 28 are organizations.

ABA Workforce Mix

The credential summary lists 53 RBTs and 15 BCBAs, plus 2 providers with dual BCBA-RBT credentials. These categories overlap: dual-credential providers may also be counted among the BCBA and RBT totals, so the figures are not mutually exclusive. The RBT count is more than three times the BCBA count, suggesting a larger technician pipeline than pool of potential supervisors. Because BCBAs supervise RBTs, that imbalance makes supervisory capacity a key consideration as the listed workforce grows. One provider is listed with BCBA and LABA credentials; the LABA is a state-level license layered on top of BCBA certification. Separately, 28 providers have multiple taxonomies, another overlapping classification that should not be treated as a distinct workforce group.

Demographics and Organizations

Women account for 181 providers (82%), men 36 (16%), and nonbinary providers 5 (2%). Those figures describe the full listed provider population, not ABA professionals alone. The notable-organizations field identifies no organizations appearing multiple times. Boston, Worcester, Holyoke, New Bedford and Cambridge are the leading cities in the update.

The registry points to broad behavioral-health activity and a substantial RBT presence, but expanding ABA access will also require enough BCBA supervisors to support direct-service staff across Massachusetts.
