Don Kirkpatrick’s Contribution to Learning & Development
MARCH 1, 2011
By 1959, editors for the predecessor of ASTD’s T&D magazine had heard of his approach and asked him to write an article. The name evolved from the fact that they were published as four installments, each one adding another level to the analysis. Jack Phillips began applying the four levels in the late ’60s and later extended the work by adding ROI as the fifth level. I just saw an announcement that Don will retire from the speaking circuit this year.
