Donald Kirpatrick

Donald Kirkpatrick was an expert who developed a widely used method to evaluate training programs’ effectiveness. His approach consists of four levels: 1) Reaction – how participants feel about the training; 2) Learning – what knowledge or skills they gained; 3) Behavior – how their workplace actions change afterward; and 4) Results – the overall impact on organizational goals, such as productivity or profits. This framework helps organizations assess if training is successful and worth the investment, ensuring learning translates into real-world improvements.
