Which do you prefer, an external or internal evaluator? Major Concepts and Theories 1. Evaluation is the identification, clarification, and application of defensible criteria to determine an evaluation object’s value, its merit or worth, in regard to those criteria. The specification and use of explicit criteria distinguish formal evaluation from the informal evaluations most of […]

The process of disciplined evaluation permeates all areas of thought and practice Given its many uses, it may seem almost axiomatic to assert that evaluation is not only valuable but essential in any effective system or society. Citizens look to eval- uation for accountability. Policymakers and decision makers call on it and use it Chapter

Internal and External Evaluations The adjectives “internal” and “external” distinguish between evaluations conducted by program employees and those conducted by outsiders. An experimental year- round education program in the San Francisco public schools might be evaluated by a member of the school district staff (internal) or by a site-visit team appointed by the California State

Needs Assessment, Process, and Outcome Evaluations The distinctions between formative and summative evaluation are concerned pri- marily with the kinds of decisions or judgments to be made with the evaluation results. The distinction between the relative emphasis on formative or summative evaluation is an important one to make at the beginning of a study because

Some Basic Types of Evaluation Formative and Summative Evaluation Scriven (1967) first distinguished between the formative and summative roles of evaluation. Since then, the terms have become almost universally accepted in the field. In practice, distinctions between these two types of evaluation may blur somewhat, but the terms serve an important function in highlighting the

Uses and Objects of Evaluation At this point, it might be useful to describe some of the ways in which evaluation can be used. An exhaustive list would be prohibitive, filling the rest of this book and more. Here we provide only a few representative examples of uses made of evaluation in selected sectors of

Roles and Activities of Professional Evaluators Evaluators as practitioners play numerous roles and conduct multiple activities in performing evaluation. Just as discussions on the purposes of evaluation help us to better understand what we mean by determining merit and worth, a brief dis- cussion of the roles and activities pursued by evaluators will acquaint the

The Purposes of Evaluation Consistent with our earlier definition of evaluation, we believe that the primary purpose of evaluation is to render judgments about the value of whatever is being evaluated. This view parallels that of Scriven (1967), who was one of the earliest to outline the purpose of formal evaluation. In his seminal paper,
