Illinois added 305 behavioral health providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. With 159 new providers this week, Illinois ranks as a substantial contributor to national workforce activity. The concentration signals an active, expanding behavioral health market, although the registry includes both individual practitioners and organizations across multiple specialties.

ABA Workforce Dynamics

The registry lists 17 BCBA credentials and 59 RBT credentials, plus 3 dual credentials held by providers identified as both BCBA and RBT. These categories overlap, so they should not be added as mutually exclusive provider groups. The RBT-to-BCBA pattern points to a sizeable direct-service workforce relative to the listed supervisory workforce. Because BCBAs design treatment plans and supervise RBTs, that balance may support service delivery while also underscoring the importance of expanding supervisory capacity. Other ABA-related entries, including assistant behavior analyst and PLBA designations, appear separately in the registry.

Workforce Profile

Of the 242 individual providers, 203 identified as female, 33 as male and 6 as nonbinary. Those figures correspond to 84%, 14% and 2%, respectively. The registry also includes 63 organizations, with Chicago, Naperville, Springfield, Oak Park and Peoria among the top cities. Aunt Martha's Health and Wellness, Inc. appeared 2 times, suggesting activity across multiple locations or organizational records rather than a single practitioner listing.

Illinois's strong weekly activity, broad geographic spread and RBT-heavy ABA profile suggest continued workforce growth, while the smaller BCBA pool may remain a constraint on expanding supervised ABA access.
