Collaborative Practice Agreement for Nurse Practitioners in Delaware
Yes, a written physician agreement is required. Delaware calls it a Collaborative Agreement.
Once the 2-year/4,000-hour transition-to-practice threshold is met, no collaborative agreement is required to continue practicing (24 Del.C. § 1906(20); 24 DE Admin. Code 1900 § 8.0).
Independent practice requires: ≥2 years of collaborative practice; ≥4,000 hours of clinical practice with a physician or experienced APRN in the same role/population focus.
What the collaboration must look like
The rules the physician relationship has to follow. Each fact comes from the statute or board rule listed under sources.
Proximity
below the 2-year/4,000-hour transition threshold: Available remotely (no on-site requirement)
No codified mile/minute radius or on-site requirement was found for the collaborative/mentorship relationship during the transition period (24 DE Admin. Code 1900 § 8.0).
Supervision ratio

Chart review

Prescriptive authority
below the 2-year/4,000-hour transition threshold: Covered by the practice agreement · controlled substances permitted
Full prescriptive authority, including controlled substances, is granted upon APRN licensure, subject to completing the transition requirements and standard DEA registration (24 Del.C. § 1906(20)).
at/after the 2-year/4,000-hour transition threshold: Covered by the practice agreement · controlled substances permitted
Independent prescriptive authority, no agreement-based restriction.
Written agreement
Required
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — Professional (service) corporation under 8 Del.C. Ch. 6, owned by nursing licensees — non-licensees may not hold equity. Ch. 6 does not list a nurse+physician cross-license combination the way it does for medicine+podiatry.
Ownership is legally distinct from, and unaffected by, whether the NP has reached independent-practice status.

About Delaware's rules
Delaware grants full independent practice to APRNs (NP/CRNA/CNM/CNS) after a uniform 2-year/4,000-hour transition period (24 Del.C. § 1906(20); 24 DE Admin. Code 1900 § 8.0) — this research pass treats that rule as applying identically across all four APRN roles; confirm role-specific nuance with the Board of Nursing before relying on it. PAs have no independent-practice pathway.
