This much-needed book offers trainers, consultants, evaluation professionals, and human resource executives and practitioners a hands-on resource for understanding and applying the proven principles of confirmative evaluation. Confirmative evaluation is a marriage of evaluation and continuous improvement. Unlike other types of evaluation¾which are used during the design of a learning program or applied immediately after conducting a program¾confirmative evaluation follows several months after the program is implemented. It tests the endurance of outcomes, the return on investment, and establishes the effectivenss, efficiency, impact, and value of the training over time.
