AAPM Bylaws Modernization
The Board of Directors has approved a proposal to update AAPM's governing documents. The proposed changes are modernizations, not restructurings.

Legal Compliance
As a DC nonprofit, AAPM must meet updated standards under the DC Nonprofit Corporation Act of 2010. This revision ensures full compliance.
Operational Flexibility
Operational details move to a separate RULES document the Board can update as needs evolve — preserving all fundamental member rights in the bylaws.
Modern Operations
Virtual meetings, electronic voting, and electronic communication are formally authorized — reflecting how AAPM already operates.
Member Accountability
New provisions allow members to call special meetings and remove Directors by vote — rights not currently in the bylaws.
Review the Materials
All documents are available for member review. The ballot will include the proposed bylaws, statement of necessity, and a summary of arguments for and against.

A few of the most frequently asked questions. Download the full FAQ for complete answers.
Will my dues change?
No changes to dues are proposed. The requirement that dues changes be approved by a membership vote is preserved.
Will my voting rights change?
No. Member voting rights are fully preserved under the proposed amendments. Full Members and Full-Lifetime Members retain all current voting rights.
What is the RULES document and why does it matter?
The RULES is a separate operational document the Board can update without a full membership vote. It allows AAPM to adapt to changes in the profession efficiently. All fundamental member rights remain in the bylaws.
What happens if the amendments are not adopted?
If the proposed amendments do not receive the required two-thirds vote, the current bylaws remain in effect.
