Performance technology (PT) is complex, drawing theory from instructional design, organizational development, communications, industrial psychology, and industrial engineering to name a few. The Standards of Performance Technology developed for the certified performance technology designation codified the processes used in the practice of performance improvement. The Human Performance Technology (HPT) Model of the International Society for Performance Improvement illustrates the Standards for the Performance Technology process, including the selection, design, and implementation of appropriate performance interventions. Research exists on specific PT interventions, such as problem solving, feedback, or job analysis. This foundational study considers intervention usage within organizations and the expertise of performance technologists. Findings indicate that years of experience in the field or related field is positively correlated to expertise. Some alignment was found between higher ranked PT expertise and higher ranked intervention usage within those organizations. (Contains 1 note, 7 tables, and 2 figures.)
