Signing for a Pharmacist in Washington: what the physician takes on
The agreement is mandatory for the clinician, which makes its duties mandatory for you. Washington calls the instrument a Collaborative Drug Therapy Agreement (CDTA).
Represents Washington's Collaborative Drug Therapy Agreement (CDTA) tier — one of the broadest CDTA frameworks in the U.S. (WAC 246-945-350; RCW 18.64.011) — not ordinary pharmacist licensure. A CDTA is voluntary/negotiated with any WA-licensed prescriber and must be filed with the Pharmacy Quality Assurance Commission and kept at the practice site; no numeric per-prescriber cap was found.

About Washington's rules
Washington is a full-independence state for ALL FOUR ARNP roles (NP, CRNA, CNM, CNS) under RCW 18.79, not just NPs — confirmed current via WAC 246-840-300/420 and Board of Nursing guidance. PAs are separate: HB 2041 (eff. Jan. 1, 2025) replaced supervision-only with a 4,000-hour supervision→collaboration tier (RCW 18.71A.120) with no numeric ratio cap.
