Growing and engaging ACS membership through innovative programs, benefits and opportunities.

The ACS President’s Challenge

Every local section, technical division, and international chapter is encouraged to help grow and strengthen the ACS membership. By combining our home office recruitment efforts with the efforts of ACS sections, divisions, and international chapters, we will maximize our outreach to prospective members and get the most out of our global recruitment efforts.

Council members, section and division chairs as well as section and division members interested in participating in the ACS President’s Challenge should take advantage of ACS resources such as the membership recruitment toolkit.

Who We Are

The Membership Affairs Committee (MAC) consists of ACS Members, Associates and Consultants. Members and Associates must also be ACS Councilors. Members are appointed to two-year terms (up to a maximum of three consecutive terms), by the ACS president-elect.

Associates and Consultants are selected to one-year terms. The total committee usually has under 30 participants (12-20 of which are Members). MAC currently consists of several working groups, which discuss, research, and make recommendations on the current needs of the ACS membership or tasks assigned by other governance entities.  

MAC welcomes your input via email. We especially appreciate feedback concerning:

  • Current MAC activities and initiatives
  • Pending petitions for changes in the ACS Constitution and Bylaws
  • Nontechnical benefits available to ACS members
  • Member recruitment and retention activities
  • Initiatives that MAC should be pursuing
  • Ways of increasing the value of ACS membership
