Supervision Agreement for Certified Nurse-Midwives in Wisconsin
No. Certified Nurse-Midwives practice independently here. Wisconsin does not require one.
Uniquely among Wisconsin's four APRN roles, CNMs are automatically licensed under the new APRN system with NO 3,840-hour/24-month transition requirement — the APRN Modernization Act carves midwives out of the general transition-to-practice framework entirely.

Prescriptive authority
Covered by the practice agreement · controlled substances permitted
Schedule II-V with DEA registration, same CE requirement as other Wisconsin APRN roles.
Written agreement
Not required
Unconditional since the APRN Modernization Act (eff. Sept. 1, 2026) — CNMs are auto-licensed with no collaborative-agreement requirement, unlike the other three APRN roles above, which must transition through a collaborative period first.
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — Service Corporation under Wis. Stat. ch. 180, subch. XIX — a CNM may co-own a multi-discipline service corporation as a health care professional; non-licensees may not hold equity.

About Wisconsin's rules
The APRN Modernization Act (2025 Act 17) took effect September 1, 2026 — days before this data's last-verified date — replacing permanent NP/CRNA/CNS collaborative arrangements with a 3,840-hour/24-month transition to independent practice; CNMs are auto-licensed with NO such threshold. Given how recent this is, verify current DSPS/Board of Nursing implementation guidance before relying on transition-period details below.
