Instructor competencies, offered as professional development frameworks, identify the knowledge, skills, and attitudes that enable effective instruction. A 2021 version of Instructor Competencies is now available from The International Board for Standards, Training, Performance and Instruction (IBSTPI). These 2021 standards, appropriate for instructors and trainers in all settings, are based on well-established instructional principles that are flexible enough to allow for adjustments to new understandings in the science of teaching and learning, the integration of best practices, and adaptability to emerging tools and technology. With this update of IBSTPI's 2004 Instructor Competencies, the framework now includes four domains of performance, 19 competencies, 150 performance statements and these three conditions defining instructors' work: core, blended, and online.
