Your boss does not believe evaluating the current training system in your organization is important. He believes any evaluation is not valid, but admits he does not really understand the idea of validity and evaluation designs. He wants you to create a memo for the Board of Directors. In this memo explain:

1) the importance of validity and designs you learned from Chapter 6.

2) internal and external threats to validity

3) a design you recommend in detail

4) and how your chosen design will limit some threats to validity.
