This document contains an introduction to the Ohio Integrated Technical and Academic Competency (ITAC) and Specialization ITAC; an overview of the dental assistant occupation; a list acknowledging professionals who helped develop the competency list; and the comprehensive list of the professional or occupational competencies deemed essential for graduates to be able to perform proficiently when they graduate from an Ohio specialization workforce development program for dental assistants. The introduction explains the following: (1) critical academic, employability, and information technology skills have been integrated throughout the list to support the technical skills; (2) the competency profile can be used as the basis for curriculum development in Ohio's secondary, adult, and postsecondary programs; and (3) the specialization competency profile is organized so that it can be clustered or grouped in a modular approach. The overview of the occupation, addressed to the reader considering preparing to be a dental assistant, describes general duties, some specific tasks, employment opportunities, length of program, type of program (classroom instruction and/or work experience), and types of certificates and/or degrees. The competencies are grouped under broader skills that are, in turn, categorized under these 13 major topics: dental assistant orientation; dental anatomy; infection control and hazards management; general health; emergency procedures; preventive dental assisting procedures; chairside assistance; dental specialties; dental laboratory procedures; dental office procedures; radiographic procedures; communications; and professionalism.
