This document contains Illinois Occupational Skill Standards for occupations in the Information Technology Design and Build Cluster (technical writer, programmer, system analyst, network architect, application product architect, network engineer, and database administrator). The skill standards define what an individual should know and the expected level of performance required in an occupational setting. The standards focus on the most critical work performances for an occupation or occupational area. Each skill standard contains the following components: performance area, performance skill, skill standard, performance elements, and performance assessment criteria. Following an introduction that explains the standards and their components and includes a performance skill-level matrix, the document contains skill standards for the following areas: (1) analysis; (2) system design; (3) visual design; (4) functional design; (5) multimedia production and acquisition; (6) development; (7) testing; (8) implementation; (9) education and training; (10) documentation; and (11) project management. Six appendixes include glossaries of information technology terms and occupational skill standards terms; lists of members of the Illinois Occupational Skill Standards and Credentialing Council, the Communications Subcommittee, and the Information Technology Design/Build Cluster Standards Development Committee; and workplace skills standards.
