Supervision Agreement for Certified Nurse-Midwives in Maine
No. Certified Nurse-Midwives practice independently here. Maine does not require one.
Maine CNMs practice with full independent authority from initial APRN licensure, with no physician-supervision or collaborative-agreement requirement — a materially different framework from general NPs' 24-month pathway.

About Maine's rules
Maine's provider categories follow different independence models: NPs graduate to full practice after 24 months of registered (not written-agreement) supervision; PAs graduate after 4,000 documented clinical hours but still need a lighter 'practice agreement' afterward; CNMs/CNSs appear independent from initial licensure; and CRNAs remain physician/dentist-accountable except in critical-access/rural hospitals. Do not assume a single APRN framework applies uniformly.
