This document discusses training evaluation and the Kirkpatrick model. It defines training evaluation as examining a training program to see if it achieved its desired effects. The Kirkpatrick model provides a framework for evaluation with four levels - reaction, learning, behavior, and results. Reaction evaluates satisfaction and engagement. Learning evaluates knowledge and skills acquisition. Behavior evaluates on-the-job application. Results evaluates tangible outcomes like productivity and costs. Proper evaluation is important for improving training programs and understanding their organizational benefits.
