Document Summary

Reaction to pretest: use of test before training causes trainees to pay attention to material on test. Reaction to evaluation: being evaluated causes trainees to try harder in training program. Interaction of selection & training: characteristics of trainees influence program effectiveness. Interaction of methods: results of trainees who received different methods can be generalized only to trainees who receive same training in same order, types of evaluation designs: Post-test-only design: only post-training outcomes are collected, design can be strengthened by adding comparison group, helps rule out alternative explanations for changes. Appropriate when trainees can be expected to have similar levels of knowledge/behavior/results outcomes prior to training. Pretest/post-test: both pretraining & posttraining outcome measures are collected, there is no comparison group, makes it difficult to rule out effects of business conditions/other factors as explanations for changes. Often used by companies that want to evaluate training program but are uncomfortable w/ excluding certain employees. Intend to train only small group of employees.
