The question "How should one decide which jobs are related to a training program?" must be answered directly and consistently before specialized training can be planned or evaluated. A conceptual framework is needed to provide a useful structure for thinking about the concept of training-related jobs, and certain issues must be resolved…

Vocational education research and development (R&D) product evaluations are difficult to conduct for several reasons, such as the many types of R&D products, the multiple users of the products with different goals for evaluation, the limited time available, and the high cost. In order to meet these challenges, an internal evaluation team…

The methodology and findings of the Law-Related Education Project's research reports which evaluated the effects on secondary students of law-related education (LRE), are discussed.
