Donald L. Kirkpatrick

Donald L. Kirkpatrick was an American educator best known for developing the Kirkpatrick Model, a framework for evaluating training programs. Introduced in the 1950s, the model outlines four levels of evaluation: reaction (how participants feel about the training), learning (what knowledge or skills they gained), behavior (how they apply what they learned in the workplace), and results (the overall impact on the organization). Kirkpatrick's work has significantly influenced how organizations assess the effectiveness of their training initiatives, helping ensure that training investments lead to tangible benefits.
