Although a dollar amount cannot be specified, it is possible to describe the kinds of information you can obtain from evaluations at different cost levels. Think of the process of building a house. If you spend a small amount of money, you can build the foundation for the house. Additional money will be required to frame the house and still more money will be needed to put on the roof. To finish the inside of the house so that it is inhabitable will require even more money.
Evaluation is similar.
Some general guidelines follow on what you may be able to get at different evaluation cost levels. Lowest cost evaluations. If you spend only a minimal amount of money, you will be able to obtain numerical counts of participants, services, or products and information about the characteristics of participants. You also may be able to find out how satisfied participants were with the services or the training. But this is only the foundation for an evaluation.
