For nurse practitioners · Colorado
Colorado APRNs hold independent practice authority from licensure, but full prescriptive authority requires first obtaining provisional prescriptive authority and then completing a 750-hour structured prescribing mentorship with a Colorado physician or fully-prescribing APRN.
Colorado splits the question in two, and the split matters. Practice authority is fully independent at licensure — no physician oversight of the clinical role, ever. The transition applies only to prescribing: provisional prescriptive authority first, then a 750-hour structured prescribing mentorship with a Colorado physician or a fully-prescribing APRN, completed within three years of the provisional grant.
The transition
750-hour prescribing mentorship (completed within 3 years of the provisional grant); practice itself is independent from day one
The moment it ends
The mentor's signature and attestation verifying successful completion of the 750-hour mentorship, which converts provisional prescriptive authority to full prescriptive authority through the Board of Nursing
The timeline
SB 23-167 signed and effective May 25, 2023 (reduced mentorship from 1,000 hours set by HB 20-1216 in 2020; approximately 3,600 hours before that)
SB 23-167 (signed May 25, 2023) not only cut the prescribing mentorship to 750 hours — it made it unlawful for a mentor to require payment or employment as a condition of the mentorship, outlawing Colorado's pay-to-mentor market.
C.R.S. §12-255-112(4)(b)(I)(A), as amended by SB 23-167 (2023)
Practice scope is fully independent at licensure with no physician oversight; the transition gate applies only to prescribing. During the provisional period the APRN prescribes within the mentorship; after full authority, prescribing includes controlled substances subject to the opioid-prescription limits built into C.R.S. 12-255-112. Provisional authority expires if the mentorship is not completed within 3 years.

Built, on sample data for now
During the transition, someone signs — and the signature is a cost line, in money or in kind. Independence retires it. What Gale adds is built to stay just as legible.
The deepest state cluster we have built is California’s — eight guides on the 103/104 ladder, cited to the statute and the board’s own filings. They are California’s rules, not Colorado’s; the same treatment is coming state by state. Until then, they show the depth of homework to expect from us.
