The document discusses several models for evaluating training programs: Kirkpatrick's model, Phillips' ROI model, the CIPP model, and the COMA model. Kirkpatrick's model defines four levels of evaluation - reaction, learning, behavior, and results. Phillips' model adds a fifth level to Kirkpatrick's - return on investment (ROI). The CIPP model evaluates context, inputs, process, and products. The COMA model measures cognitive learning, organizational environment, motivation, and attitudes.
