Advisory committees are used often in evaluation studies, yet this practice is little discussed or reported. This issue is the first full-length text devoted to the purpose, practice, and scholarship about this type of formal, structured advice.

It includes case studies and analyses of these to answer such basic topics as:

• What is an evaluation advisory group (EAG)?
• Why (not) use an EAG?
• How to organize an EAG, and how to evaluate it?

This is the 136^th volume of the Jossey-Bass quarterly report series New Directions for Evaluation, an official publication of the American Evaluation Association.
