Summary — HB 4146 (Introduced 2025)

Title: Health occupations: psychologists; supervised postgraduate experience requirements; modify. (Adds MCL 333.18223a to 1978 PA 368; tie-bar with HB 4165'25)

Purpose / Intent

The bill adds a new section (18223a) to Michigan’s Public Health Code to regulate supervision requirements for individuals issued a “limited license” under MCL 333.18223(2) (postgraduate/limited psychologist licensure). Its intent is to require supervisory oversight by a fully licensed psychologist for limited-license holders, with narrow exceptions for certain government or nonprofit employees and special rules where autism spectrum disorder (ASD) diagnoses are involved.

Key provisions

  • Adds MCL 333.18223a to the Public Health Code.
  • Transitional rule (first 180 days after the amendatory act’s effective date): the licensing board must place one limitation on any license issued under MCL 333.18223(2) requiring supervision by a psychologist who holds a non‑limited (full) license — except for duties performed as an employee of a governmental entity or of a nonprofit organization serving benevolent and charitable purposes.
  • After the initial 180 days: each limited license under MCL 333.18223(2) must include one limitation requiring supervision by a fully licensed psychologist.
  • Exception for government/nonprofit employees:
    • The supervision limitation does not apply if the individual is not diagnosing patients with an autism spectrum disorder.
    • If the individual is diagnosing ASD, the exemption applies only if the individual has held the limited license for at least 3 years.
  • Conditional enactment clause: the amendatory act “does not take effect” unless a companion bill (identified as Senate Bill No. ____ / House Bill No. ____ request no. S00384'25 / H00384'25) of the 103rd Legislature is enacted. (This creates a legislative dependency.)

Who is affected

  • Individuals holding or seeking a limited psychologist license under MCL 333.18223(2) — they will generally be required to practice under supervision by a fully licensed psychologist.
  • Employers that are governmental entities or qualifying benevolent/nonprofit organizations — some employees in those settings may be exempt from the supervision requirement under the bill’s conditions.
  • Full-license psychologists — will serve as required supervisors for limited-license holders.
  • Licensing board (Michigan Board of Psychology or relevant board within the Department of Licensing and Regulatory Affairs) — must apply the limitation to licenses and implement the rule changes.

Procedural / timing notes

  • Introduced: Filed 02/26/2025; introduced 03/10/2025 (per chamber records). Referred to Committee on Health Policy (and other committee references appear in the legislative history).
  • Transitional supervision rule applies for the first 180 days; thereafter the supervision requirement is generally mandatory.
  • The act is conditionally effective only if the referenced companion bill(s) are also enacted (see “Enacting section”).

Potential impacts / considerations

  • Increases supervisory oversight of limited-license psychologists, which may aim to protect client safety and ensure clinical competence during postgraduate practice.
  • Could restrict autonomous practice opportunities for limited-license holders, particularly those diagnosing ASD, unless they meet the 3‑year limited license tenure or work in settings where the exemption applies.
  • Employers (government and qualifying nonprofits) may need to track license tenure and supervision status for staff diagnosing ASD to determine exemptions.
  • Practical effect depends on the companion bill’s enactment — the bill may not take effect without the specified related legislation.

Important note on source materials

The legislative files provided include mixed/contradictory content: an unrelated Illinois appropriation bill text (an Illinois HB 4146 appropriating $5,000,000 for levee work) appears alongside the Michigan Public Health Code amendment. The summary above reflects the Michigan Public Health Code amendment language (addition of MCL 333.18223a) and the Health Policy committee referral. If you need, I can verify the official, current Michigan bill text and status from the Michigan Legislature website to confirm final language and whether the companion conditional bill has progressed.
