"Measuring Performance in Engineering Education" is a guide to assessment in engineering education. It explains the development of the assessment program at the Albert Nerken School of Engineering, The Cooper Union, and shows you how some of our most successful assessment projects were implemented. The goal in creating this electronic publication is to make available for the assessment public a set of examples implemented in one of the first engineering schools to develop assessment in the United States. We believe that we have accumulated valuable experience in developing and implementing assessment, and that you might find our examples helpful. We present the reader with 15 selected assessment projects designed at The Cooper Union between 1997 and 2001 --their rationale, objectives, and process. What you will find in these pages are ideas about implementing a new program from scratch as well as detailed information about how to develop specific assessment projects in an engineering school. The book includes examples of the questionnaires used to gather data, and the tables and graphs used to report results. The book constitutes a guide for assessment practitioners engaged in innovative work at their institutions. It will help you to come to terms with methodological and practical questions related to assessment as they develop in practice.
