This document discusses various models and methods for evaluating training programs to determine their effectiveness. It describes several frameworks for training evaluation, including Kirkpatrick's four-level model of reaction, learning, behavior, and results. It also discusses other models that build on Kirkpatrick's, such as Phillips' addition of return on investment and Kaufman's five levels. The document advocates regular evaluation of training programs to identify areas for improvement and determine whether programs should be continued or cancelled based on whether they meet organizational goals and objectives.
