This Infoline presents a set of core competencies for trainers-based on the ASTD Competency Model's foundational competencies-that fall into the categories of business and management (understanding the basics of business), interpersonal (being a great communicator and influencer), and personal (possessing adaptability and the ability to think ahead). For the trainer who continually works to improve his or her skills, this issue will enable him or her to develop and demonstrate these competencies on the job, assess competencies that may need to be developed further, and chart a path for future growth.
