Animals used in biomedical research at Northwestern University are housed either in CCM facilities or in facilities administered by academic departments for which CCM provides the primary care and oversight. CCM has been AAALAC (Association for Assessment and Accreditation of Laboratory Animal Care, International) Accredited since 1985 and a member of AALAS (American Association for Laboratory Animal Science) since 1962.
