This document, which is intended as a guide for workforce preparation program providers, details the Illinois occupational skill standards for programs preparing students for employment in occupations in the (vehicle) collision repair technician cluster. It begins with a brief overview of the Illinois perspective on occupational skill standards and credentialing, the process used to develop the skill standards, assumptions underlying the standards, and performance skill levels. Presented next are skill standards for 46 tasks typically performed in the following areas of collision repair: structural analysis and damage repair; nonstructural analysis and damage repair; mechanical and electrical components; plastics and adhesives; painting and refinishing; and estimating. 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 (3) performance assessment criteria. The following items are attached and appended: a matrix cross-referencing Automotive Service Excellence Tasks and the Inter-Industry Council on Auto Collision Repair Uniform Procedures for Collision Repair with related Illinois state standards; a collision repair glossary; a glossary of education-related terms; lists of Illinois Occupational Skill Standards and Credentialing Council, Transportation, Distribution and Logistics Subcouncil, and Collision Repair Technician Cluster Standards Development Committee members; and a list of necessary workplace skills.
