Selecting and Using Early Childhood Rating ScalesAmerican Guidance Service The purpose of this article is to help rating scale users organize their thinking about why and how rating scales are to be used and to provide them with information that will be useful in evaluating the adequacy of available rating scales. The first part of the article discusses issues related to establishing a rationale for the use of rating scales, pointing out questions that should be asked regarding purposes for and means of implementing scale use. The second part discusses issues related to selecting a rating scale to meet user needs, such as user friendliness, scale format, score interpretation, reliability, and validity. The section on reliability contains an expanded discussion of how to evaluate the reliability of a scale and the factors that can affect reliability. The validity section focuses discussion on two questions: Does the scale measure the trait validly? Can the scale be validly used to serve its intended purposes? Various methods for establishing the validity of a rating scale are discussed in relation to these two questions. Special attention is given to discussing the effects that rating scale score distributions can have on a scale's validity for specific purposes.
