This publication outlines recommended minimum competencies for training and development personnel, as developed by the Professional Development Committee of the Ontario Society for Training and Development. It is intended to provide basic checklists of necessary skills, knowledge, and behaviors for each of four categories of training and development personnel identified by the committee. These categories include instructors, designers, managers, and consultants. Most of the publication consists of a chart entitled "Schedule of Descriptors," which lists specific skills and behaviors for each of 11 core competency areas that are relevant to one or more of the four categories of training and development personnel.
