AAALAC International is a private, nonprofit organization headquartered in Frederick, Maryland, that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs.^[1][2] The accreditation program started in 1965, when some veterinarians and researchers organized the American Association for Accreditation of Laboratory Animal Care, or AAALAC.^[3] In 1996, AAALAC changed its name to the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC International). The organization said the name change reflected the organization's growth in other countries and its commitment to enhancing life sciences and quality animal care around the world. Since 2016, the organization is officially known only by its acronym, AAALAC International.^[4] There are currently about 1,000 organizations worldwide accredited through its program.
