PMHNP Practice Requirements in Delaware: Scope, Prescribing & Collaboration

Please Read First

Informational only, not legal advice. Requirements change, so verify with the Delaware Board of Nursing and the AANP State Practice Environment map. Last reviewed: July 2026. This page focuses on PMHNPs but reflects general nurse practitioner rules in Delaware, which differ by role and change over time, so always confirm your specific situation with the Delaware Board of Nursing.

Practice Authority

Delaware Practice-Authority Category (Full Practice)

AANP currently classifies Delaware as a full practice state on its State Practice Environment map. In practice, that means a PMHNP in Delaware may evaluate and diagnose patients, order and interpret tests, and initiate and manage treatments, including prescribing medications, under the exclusive licensure authority of the Delaware Board of Nursing, without a state-mandated career-long collaborative or supervisory agreement. An initial period of collaborative practice hours may apply before fully independent practice. Because these designations and the rules behind them can change, confirm the current category directly with the Delaware Board of Nursing and the AANP map before you rely on it.

You can see how Delaware compares nationally on the AANP State Practice Environment map and review state-specific detail on AANP’s practice information by state. For the controlling rules, go to Delaware Board of Nursing.

Collaboration

Is a Collaborative or Supervisory Agreement Required?

In a full practice authority state like Delaware, an ongoing, career-long collaborative or supervisory agreement is generally not required in order to practice. Some full practice authority states do, however, require a defined transition-to-practice period of supervised or collaborative practice before a nurse practitioner moves to fully independent practice. Whether any such transition requirement applies to you, how long it lasts, and how it is documented are set by state rule and can change, so confirm the current requirements with the Delaware Board of Nursing rather than relying on a summary.

For a plain-language walkthrough of what these arrangements typically contain, see our guide to PMHNP collaborative practice agreements, and compare requirements across states on our PMHNP scope of practice by state overview.

Prescriptive Authority

Prescriptive Authority and Controlled Substances

Delaware nurse practitioners who meet the state’s requirements may be granted prescriptive authority, and in general that authority can extend to controlled substances when the appropriate conditions are met. Controlled-substance prescribing also requires a separate federal DEA registration, and some substances carry additional federal or state conditions. Because the specific scope, any limits, and the documentation tied to prescriptive authority are governed by state law and board rule, verify the current details with the Delaware Board of Nursing and the U.S. Drug Enforcement Administration before prescribing.

Controlled-substance prescribing is regulated at both the state and federal level. For the federal side, see the U.S. Drug Enforcement Administration, and for the state side, confirm current rules with Delaware Board of Nursing.

Credentialing Is a Separate Track

Scope of practice decides how you can practice in Delaware. Getting paid is a separate track, with its own payer rules, Medicaid program, and enrollment timelines. We cover that in detail on the Delaware credentialing and payer enrollment page, and nationally in our PMHNP credentialing guide.
