Pennsylvania recorded 256 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. That share signals a meaningful contribution to national registry activity, though NPI listings do not establish hiring, staffing levels or appointment availability. The update includes 129 new this week and 149 new this year; those reporting periods are registry counts, not measures of service capacity.

ABA Workforce Mix

The credential summary lists 28 BCBAs and 53 RBTs, plus 4 dual credentials. The dual BCBA-RBT records may overlap with both credential totals, so these categories are not mutually exclusive. The RBT count is nearly twice the BCBA count, pointing to more listed technicians than potential supervisors. Because BCBAs supervise RBTs, that gap makes supervisory capacity important when assessing whether technician presence can translate into delivered ABA services. The registry also counts 51 providers with multiple taxonomies; those classifications can overlap and should not be read as distinct workforce groups.

Demographics and Organizations

The listed population includes 175 women (84%), 23 men (11%) and 10 nonbinary providers (5%). These figures cover the broader provider group, not ABA workers alone. ABH Pennsylvania Childrens Services Inc. appears twice in the notable-organizations field. Philadelphia and Pittsburgh are among the listed leading cities, alongside Bethlehem, Allentown and Du Bois.

The registry suggests a larger RBT pool than BCBA pool in Pennsylvania, making growth in supervisory capacity a key factor for expanding reliable ABA access.
