Donald Kirkpatrick (March 15, 1924 – May 9, 2014) was Professor Emeritus at the University of Wisconsin in the United States and a past president of the American Society for Training and Development (ASTD). He is best known for creating a highly influential 'four level' model for training course evaluation, which served as the subject of his Ph.D. dissertation in 1954. Kirkpatrick's ideas were published to a broader audience in 1959 in a series of articles in the US Training and Development Journal, but they are better known from a book he published in 1994 entitled Evaluating Training Programs. Other books that he has written on training evaluation include Transferring Learning to Behavior and Implementing the Four Levels.; Prof. of Management at the Management Institute, Univ. of Wisconsin; b. 3/15/24
