Book excerpt: Evaluation Basics is the perfect tool for individuals wishing to build or enhance practical training evaluation skills from frontline trainers and designers of training to subject matter experts who occasionally function as a trainer. The four carefully constructed chapters on each of Kirkpatrick's classic four levels of evaluation offer you a clear path to success. Plus, you will find two invaluable chapters on how biases creep into all levels of evaluation and a chapter on how to communicate evaluation results effectively. Practical examples, worksheets, checklists, tips, and notes are included throughout the book.
