ACM Professional Chapter Membership Requirements
The ACM Bylaws specify the membership requirements for Professional and student chapters:
Each ACM General Interest chapter must have a minimum of three officers at all times; a Chair, Vice-Chair, and Treasurer. The bylaws received by all chapters contain valuable information as to the individual duties all officers should execute; all amendments to the bylaws must receive approval by the ACM Chief Operating Officer. These approvals must be obtained before any amendment may be distributed for a vote to the members of the chapters.
The officers of a chapter will be elected and vacant offices filled as provided in its bylaws. All officers in student chapters must be ACM members. All officers in professional chapters must be ACM Members."
As chapters are subsidiaries of the ACM and share the non-profit status thereof, membership is required for indemnification against damage and loss:BYLAW 16: INDEMNIFCIATION
"The Association shall indemnify any person who was or is a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that the person is or was a member of the Council or an officer of the Association."
In addition to the chapter officers, chapters must consist of chapter members. To be considered active and viable by ACM, chapters must have a minimum of 10 members. Non-officer members are not required to have ACM membership, but ACM must be notified of all active chapter members by adding them through the chapter's web account. Chapters that fail to meet this minimum membership requirement jeopardize their status with the Association.
Student chapters must have a faculty sponsor. This sponsor must have ACM Professional Membership.
Officers of SIG chapters must have both ACM and the respective SIG membership.
