This document contains 31 competencies organized by these three themes related to effective adult instruction: (1) keeping current in content area and in instructional strategies; (2) communicating and collaborating with colleagues and learners to facilitate learning; and (3) working positively and nonjudgmentally with diverse populations. The specific skills that instructors can develop within these themes promote quality instruction across a variety of missions, program goals, and instructional content. For each competency, performance indicators and evidence examples that demonstrate the specific competency in practice are listed. The competencies are organized into these six categories: professional development, instructional delivery, management of instructional resources, assessment and monitoring of learning, management of program responsibilities and program organization, and providing learner guidance and referral. Three sections discuss the purposes of the competencies, the methodology for developing them, and ways in which they can be used; describe instructor competencies and performance indicators; and include a table containing each of the instructor competencies and performance indicators. Three appendixes provide illustrations of the performance indicators, a self-assessment instrument for instructors, and recommended professional development activities. (KC)
