This document, which is intended to serve as a guide for workforce preparation program providers, details the Illinois occupational skill standards for programs preparing students for employment as surgical technologists. The document begins with a brief overview of the Illinois perspective on occupational skill standards and credentialing, the process used to develop the skill standards, and assumptions underlying the standards. Presented next are skill standards for 49 tasks typically performed by surgical technologists in the preoperative, intraoperative, and postoperative phases of treatment. Each skill standard statement contains the following components: (1) the actual skill standard (including the conditions of performance, work to be performed, and performance criteria); (2) performance elements and assessment criteria; and (3) a recommended assessment and credentialing approach. The following are among the tasks for which skill standards are provided: obtain appropriate sterile and unsterile items for procedures; maintain highest standards of aseptic technique during procedures; and assist with preparing operating rooms for subsequent patients. Appended are the following: glossary; lists of Illinois Occupational Skill Standards and Credentialing Council, Health and Social Sciences Subcouncil, and Surgical Technologist Standards Development Committee members; Health and Social Sciences Subcouncil Surgical Technologist Standards recognition proposal; and a list of necessary workplace skills.
