Tennessee recorded 123 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. That share signals a modest concentration of registry activity relative to the country, not a measure of the state’s total workforce or service availability. The update reports 65 new records this week and 77 this year; 109 are individuals and 14 are organizations.
ABA Workforce Mix
The credential summary lists 12 BCBAs and 48 RBTs, a four-to-one ratio of technician records to BCBA records. Four providers are reported with dual BCBA-RBT credentials. These credential categories overlap: dual-credential providers may also be counted in the BCBA and RBT totals, so they should not be added as a separate workforce group. The larger RBT count points to a technician-heavy mix, while the smaller BCBA count underscores the importance of supervisory capacity. BCBAs supervise RBTs, and the registry counts alone cannot show whether supervisors are available where technicians or clients need them.
Demographics and Organizations
Women account for 87 providers, or 80%; men account for 14, or 13%; and nonbinary providers account for 8, or 7%. These figures cover the reported provider population, not necessarily ABA professionals alone. The update’s notable-organizations field is empty, so it does not identify organizations appearing multiple times there. Knoxville, Nashville, Memphis, Clarksville and Chattanooga are the listed leading cities. The registry also reports 31 providers with multiple taxonomies, another classification overlap rather than a separate workforce category.
Tennessee’s records suggest a broad pool of RBTs relative to BCBAs, making the distribution and availability of BCBA supervision key considerations for expanding ABA access.
