Can you believe my four articles on Reaction, Learning, Behavior, and Results were printed in ASTD’s Training & Developmentjournal more than 50 years ago? Immediately, they began to get the attention of training people. Some called them the “four levels,” while others named them the “Kirkpatrick Model” for evaluating training programs.
I had not called them either one. They were based on my 1954 dissertation for my Ph.D. at the University of Wisconsin and research I had done between 1954 and 1959.
