Supervising Physicians

Note: The Oregon Legislature passed HB 3036(2021) to shift PA practice from a supervision to a collaboration model. Starting July 15, 2022, a physician may not apply to be a supervising physician. See the HB 3036 webpage for more information.

Application and Approval

Prior to using the services of a physician assistant (PA), a physician must be approved as a supervising physician by the Board. This one-time application is submitted online and includes a 20-question, open-book exam on supervising physician requirements and responsibilities. The application fee is $100. The Board makes a determination on the application within seven (7) days unless the physician is under a Board investigation.  Supervising physician approval does not need to be renewed (see OAR 847-050-0027 and OAR 847-050-0037).

Once approved by the Board, a supervising physician may use the services of a physician assistant (PA) in accordance with a practice agreement
You may apply to be a supervising physician at Licensee Services.

Supervising Physician Organization (SPO)

A “Supervising Physician Organization” (SPO) is a group of supervising physicians who collectively supervise the physician assistant(s). Effective September 1, 2016, all supervising physicians in a SPO must apply to the Board before supervising a PA (see OAR 847-050-0037).
Supervising physicians within a SPO are subject to the same responsibilities, requirements, and supervisory duties as any other supervising physician except that the supervision may be shared and physician-to-PA ratios do not apply.

Establishing and Maintaining a SPO

A letter should be sent to the Board, preferably on the organization's letterhead, providing the name of the SPO, the name of the primary supervising physician, and the names of all member physicians who will be supervising physician assistants as part of the SPO. The SPO must ensure that the list of supervising physicians is continually updated with any changes and sent to the Board.

Designation of Primary Supervising Physician

One physician within the SPO must be designated as the primary supervising physician. The primary supervising physician is responsible for the administrative direction of the SPO and may also provide clinical supervision. The primary supervising physician must submit, modify, and terminate the practice agreements for PAs who are supervised by the SPO.


An agent is a physician designated in writing to supervise a physician assistant when the supervising physician is unavailable for short periods of time, such as but not limited to when the supervising physician is on vacation.  The agent must be an Oregon-licensed physician in good standing. In the absence of the supervising physician, the agent assumes the same responsibilities as the supervising physician (see OAR 847-050-0038). 

An Agent Acknowledgement Form memorializing this agreement should be kept at the primary practice site (not filed with the Board).

Note: Agents may not be used by Supervising Physician Organizations.

Personal Responsibility

When the supervising physician is a member or an employee of a professional corporation or partnership, the primary supervising physician and any acting supervising physician are in all cases individually responsible for the direction and supervision of the physician assistant's work. Such responsibility for supervision cannot be transferred to the corporation or partnership (see OAR 847-050-0055).
