Arizona's medical laboratory personnel training programs were examined in relation to the nationwide development and distribution of laboratory personnel classifications (Medical Technologist--MT, Medical Laboratory Technician--MLT, and Certified Laboratory Assistant--CLA) and the national educational response which has resulted in an increase in the number of programs and program graduates and a standardization of curricula and expected competencies. Three state universities and four community colleges formally offer some level of training. Arizona Western College, Pima Community College, and Yavapai College offer only two-year transfer programs, approximately equivalent to the first two years at one of the university MT programs offered at Arizona State University, Northern Arizona University, and the University of Arizona. Phoenix College offers the two-year transfer program in addition to formal CLA and MLT training programs. Curricula data for all programs indicated that transfer programs required approximately the same courses as four-year programs, although lacking half of the humanities, social sciences, and mathematics requirements; at this level, there were no internships. The specifically accredited CLA and MLT programs required internships for completion. MT programs were broader and more in-depth. Enrollment data, plans for expansion and a bibliography are included.
