ACHE launched its chapter strategy in 2003 to increase the value of ACHE affiliation by offering local options for professional development, including education and networking opportunities. By 2007, ACHE grew from an initial 60 chapters to 83 independent chapters that provide access to US-based ACHE affiliates. While the chapter initiative has been extremely successful, it also can provide further value to affiliates and provide chapters with an opportunity for significant growth and development. Chapters have until Dec 31, 2008, to sign the new chapter agreement -- the core legal document that defines the respective obligations and duties of ACHE and its chapters. As of November 2007, 72 chapters had signed the new agreement and will operate under a combined membership structure effective Jan 1, 2008.
