Designing an evaluation is rather an art, as each must be designed according to its appropriateness to the situation being evaluated. The advantages of each feature of the design must be balanced against any sacrifices each of these choices entail.

This volume includes both new approaches to the design of educational evaluations, and discusses the pros and cons of frequently used design concepts.
