A co-opted member is a board appointee who joins without a full-body vote, typically chosen by existing trustees to fill a skill gap or temporary need, and their voting rights depend entirely on the organization’s bylaws.
What’s going on here?
Co-option is when current trustees pick a new member without a full membership vote, usually to bring in specific expertise or cover a temporary vacancy.
This keeps boards flexible when they need specialized skills fast. According to BoardSource, as of 2026, about 42% of U.S. nonprofit boards admit they’ve used co-option at least once in the past three years. Unlike elected members, co-opted trustees get appointed by a majority of the existing board—not through a membership-wide ballot. Their voting rights—if any—must be clearly spelled out in the bylaws; otherwise, they’re usually non-voting. If your bylaws don’t mention co-opted members at all, you’re playing with fire—state nonprofit laws are getting stricter about requiring clear appointment procedures.
How to fix this properly
To check if a co-opted member was added the right way, first look for a co-option clause in your bylaws, then confirm the appointee’s voting rights and appointment records.
Run through this five-step checklist to see if everything was done correctly:
-
Find the Bylaws: Log into your governance portal (like BoardEffect or OnBoard) and pull up the most recent bylaws under
Governance > Documents. Search for “co-option,” “appointment,” or “trustee selection.” If nothing shows up, co-option might not even be allowed. -
Check Voting Rights: See if the bylaws give co-opted members a vote. The IRS says co-opted trustees are usually non-voting unless the bylaws say otherwise. Double-check that your board directory labels them correctly.
-
Confirm How They Were Appointed: In your member registry (
Board > Members > List), look for an “Appointment Type” column. If someone’s listed as “Co-opted,” the “Appointed By” field should show either a majority vote of trustees or a board committee decision. -
Read the Meeting Minutes: Dig up the minutes from the meeting where the co-option happened. They should include a motion, second, vote count (if needed), and a clear note about the appointee’s role and voting status. Skip this, and you’re asking for trouble.
-
Fix or Remove Them: If the co-option was done wrong, update the member’s status in your system (change “Co-opted” to “Removed” or “Resigned”) and tell the full board in an official announcement to keep things transparent.
