Extent of Learning
Some organizations administer tests to determine what the participants in a T&D program have learned. T he pretest-posttest control group design is one evaluation procedure that may be used. In this procedure, both groups receive the same test before and after training. The experimental group receives the training but the control group does not. Each group receives randomly assigned trainees. Differences in pretest and posttest results between the groups are attributed to the training provided. a potential problem with this approach is controlling for variables other than training that might affect the outcome.
