The revised requirements simply specify a set of core competencies. These are a subset of the competencies already covered by most programs. Certification implies that a set of standards have been met. Unless requirements are public it is not possible to evaluate if they are reasonable and to conduct a dialogue of what constitutes appropriate educational preparation. Accreditation evaluates the overall quality of the educational program.
Certification evaluates the qualifications of individuals.
ARRT's competency requirements are intended to assure that each individual has met certain clinical and didactic requirements. Accreditation adds value to the process, but does not serve as a substitute for the evaluation of individuals. Certification requires more than just passing the Registry examination. Certification's focus is on the cognitive, psychomotor and affective domains. That is, does the candidate understand the principles underlying professional practice, is the candidate able to perform specific skills, and has the candidate internalized a value system appropriate for professional practice.
