In Gargani and Strong (2014), we describe The Rapid Assessment of Teacher Effectiveness (RATE), a new teacher evaluation instrument. Our account of the validation research associated with RATE inspired a review by Good and Lavigne (2015). Here, we reply to the main points of their review. We elaborate on the validity, reliability, theoretical…

This chapter describes a concrete process that stakeholders can use to make predictions about the future performance of programs in local contexts. Within the field of evaluation, the discussion of validity as it relates to outcome evaluation seems to be focused largely on questions of internal validity (Did it work?) with less emphasis on…

The 1999 "Standards for Educational and Psychological Testing" defines validity as the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests. Although quite explicit, there are ways in which this definition lacks precision, consistency, and clarity. The history of validity has taught us…

In this article, we highlight the need for a precisely defined construct in score-based validation and discuss the contribution of cognitive theories to accurately and comprehensively defining the construct. We propose a framework for integrating cognitively based theoretical and empirical evidence to specify and evaluate the construct. We apply…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

This body of evidence summary reports the results of the evaluation of technical evidence in support of the California English Language Development Test (CELDT), as analyzed against a validated list of technical adequacy criteria. The table presented in this paper outlines the types of validity, reliability, and bias and sensitivity evidence…
