This publication identifies a set of recognized skills and knowledge areas possessed by effective professional development (PD) coordinators. It is designed to enable PD staff and their supervisors to think reflectively about their PD system, to identify how the system builds on the strengths of the coordinator and the PD staff, to identify where there is room for improvement in the coordination and delivery of services, and to plan and implement strategies that enhance the overall quality of their program's PD activities. A brief overview of the competency development process is followed by a description of the overall organization of the competencies into these five categories, listed in the order in which the competencies and performance indicators appear: knowledge of adult education, PD leadership, design and delivery of PD, monitoring and reporting of PD activities, and community collaboration. Suggestions are made to use the competencies to improve PD at state, local, and PD coordinator levels. Appendixes include the Professional Development Coordinator Competencies and sample section of a Professional Development Coordinator Self-Assessment Instrument that uses four-point Likert scales to rate relevance to program, self-assessment, and existence of a goal for the year.
