The role of the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) in accrediting educational programs is examined in this paper along with the level of involvement of two-year colleges in accreditation and the processes and outcomes of accreditation. First, the paper looks at the representation of two-year colleges on three accrediting review committees: (1) the Joint Review Committee for Radiography, of which 3 of 6 board members are from two-year colleges; (2) the Joint Review Committee for Respiratory Therapy, of which 8 of 13 members are two-year college representatives; and (3) the Review Board of NAACLS, of which 25% of the members are from two-year institutions. The paper then discusses the volunteer nature of accreditation, pointing to the high percentage of qualified individuals who are unwilling to participate in the process and stressing the importance of volunteers in peer review and self-regulation. Finally, the paper explores the process and outcomes of accreditation, examining selected requirements of associate degrees, problems in compliance with standards related to outcomes, and the high percentage of programs which do not receive accreditation.
