Evaluation Models is an up-to-date revision of the classic text first published in 1983. Organized in three sections, the first includes a historical perspective on the growth of evaluation theory and practice and two comparative analyses of the various alternative perspectives on evaluation. The second section includes articles representing the major schools of thought about evaluation written by the leaders who have developed these schools and models. The final section describes and discusses the Standards for Program Evaluation and the reformation of program evaluation.

This volume is organized around four dominant, interrelated core issues: professional standards; a guide to applying the Joint Committee's Standards; ten alternative models for the evaluation of teacher performance; and an analysis of these selected models. The book draws on research and development conducted by the federally-funded national Center for Research on Educational Accountability and Teacher Evaluation (CREATE). It aims to explain the essence of sound teacher evaluation in such a way that readers will be able to apply its principles, facts, ideas, processes, and procedures. In addition, it explores the latest developments in teacher evaluation.

This text is organized around four dominant, interrelated core issues: professional standards; a guide to applying the Joint Committee's Standards; ten alternative models for the evaluation of teacher performance; and an analysis of these selected models. The book draws heavily on research and development conducted by the Federally-funded National Center for Research on Educational Accountability and Teacher Evaluation (CREATE). It aims to teach the essence of sound teacher evaluation and help readers to apply its principles, facts, ideas, processes and procedures. Finally, the book invites and assists school professionals and other readers to examine the latest developments in teacher evaluation.

Every school district needs a system of sound superintendent performance evaluation. School district superintendents are and must be accountable to their school boards, communities, faculties, and students for delivering effective educational leadership. To assure that they are evaluated fairly, competently, and functionally, superintendents need to help their school boards plan and implement evaluation systems that adhere to the evaluation standards. This text outlines some of the problems and deficiencies in current evaluation practice and offers professionally-based leads for strengthening or replacing superintendent performance evaluation systems. The focus is on the on-the-job performance of school district superintendents as they implement school board policy. The decision to focus on performance evaluation reflects the importance of this kind of evaluation in the move to raise educational standards and improve educational accountability. Boards and superintendents are advised to make superintendent performance evaluation an integral part of the district's larger system for evaluating district needs, plans, processes, and accomplishments.

I personally learned to know Ralph Tyler rather late in his career when, in the 1960s, I spent a year as a Fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford. His term of office as Director of the Center was then approaching its end. This would seem to disqualify me thoroughly from preparing a Foreword to this "Classic Works. " Many of his colleagues and, not least, of his students at his dear Alma Mater, the University of Chicago, are certainly better prepared than I to put his role in American education in proper perspective. The reason for inviting me is, I assume, to bring out the influence that Tyler has had on the international educational scene. I am writing this Foreword on a personal note. Ralph Tyler's accomplishments in his roles as a scholar, policy maker, educational leader, and statesman have been amply put on record in this book, not least in the editors' Preface. My reflections are those of an observer from abroad but who, over the last 25 years, has been close enough to overcome the aloofness of the foreigner. Tyler has over many years been criss-crossing the North American con­ tinent generously giving advice to agencies at the federal, state, and local levels, lecturing, and serving on many committees and task forces that have been instrumental in shaping American education.

This reference work is aimed at evaluation scholars and specialists, educators, policymakers, graduate students in evaluation and education, administrators and other school personnel, as well as personnel in funding organizations. The text: addresses both theoretical and practical areas of educational evaluation; provides up-to-date, comprehensive coverage of core concepts, methods, and areas of application; reflects the perspectives and experiences of leading evaluation scholars and practitioners from around the world; brings together a large group of notable authors presenting diverse national contexts; and presents in-depth treatment of core concepts and best ideas on how to design and conduct sound evaluations in education.

Attempting fonnally to evaluate something involves the evaluator coming to grips with a number of abstract concepts such as value, merit, worth, growth, criteria, standards, objectives, needs, nonns, client, audience, validity, reliability, objectivity, practical significance, accountability, improvement, process, pro­ duct, fonnative, summative, costs, impact, infonnation, credibility, and - of course - with the tenn evaluation itself. To communicate with colleagues and clients, evaluators need to clarify what they mean when they use such tenns to denote important concepts central to their work. Moreover, evaluators need to integrate these concepts and their meanings into a coherent framework that guides all aspects of their work. If evaluation is to lay claim to the mantle of a profession, then these conceptualizations of evaluation must lead to the conduct of defensible evaluations. The conceptualization of evaluation can never be a one-time activity nor can any conceptualization be static. Conceptualizations that guide evaluation work must keep pace with the growth of theory and practice in the field. Further, the design and conduct of any particular study involves a good deal of localized conceptualization.

Wingate The Evaluation Center, Western Michigan University, Ml, USA Educational evaluation encompasses a wide array of activities, including student assessment, measurement, testing, program evaluation, school personnel evalua­ tion, school accreditation, and curriculum evaluation. It occurs at all levels of education systems, from the individual student evaluations carried out by class­ room teachers, to evaluations of schools and districts, to district-wide program evaluations, to national assessments, to cross-national comparisons of student achievement. As in any area of scholarship and practice, the field is constantly evolving, as a result of advances in theory, methodology, and technology; increasing globalization; emerging needs and pressures; and cross-fertilization from other disciplines. The beginning of a new century would seem an appropriate time to provide a portrait of the current state of the theory and practice of educational evaluation across the globe. It is the purpose of this handbook to attempt to do this, to sketch the international landscape of educational evaluation - its conceptual­ izations, practice, methodology, and background, and the functions it serves. The book's 43 chapters, grouped in 10 sections, provide detailed accounts of major components of the educational evaluation enterprise. Together, they provide a panoramic view of an evolving field.

Every school district needs a system of sound superintendent performance evaluation. Superintendent Performance Evaluation outlines some of the problems and deficiencies in current evaluation practice and offers professionally-based leads for strengthening or replacing superintendent performance evaluation systems.

What goals should be addressed by educational programs? What priorities should be assigned to the different goals? What funds should be allocated to each goal? How can quality services be maintained with declining school enrollments and shrinking revenues? What programs could be cut if necessary? The ebb and flow of the student population, the changing needs of our society and the fluctuation of resources constantly impinge on the education system. Educators must deal with students, communities, and social institutions that are dynamic, resulting in changing needs. It is in the context of attempting to be responsive to these changes, and to the many wishes and needs that schools are asked to address, that needs assessment can be useful. Needs assessment is a process that helps one to identify and examine both values and information. It provides direction for making decisions about programs and resources. It can include such relatively objective procedures as the statistical description and analysis of standardized test data and such subjective procedures as public testimony and values clarification activities. Needs assessment can be a part of community relations, facilities planning and consolidation, program development and evaluation, and resource allocation. Needs assessment thus addresses a xiii XIV PREFACE broad array of purposes and requires that many different kinds of procedures be available for gathering and analyzing information. This book was written with this wide variation of practices in mind.
