This chapter broadly reviews measurement theory, scale development, testing, and assessment. The chapter is divided into two broad areas to represent distinct phases of testing involving test development and test application. A model is provided to illustrate the integrated role of testing with measurement and assessment components. Theories of measurement are reviewed with the use of the Item Response Theory, not only for the purpose of objective measurement, but as a basic model to analyze how personal attributes interact with test stimuli. Interpretive phases of tests within an assessment...

This chapter broadly reviews measurement theory, scale development, testing, and assessment. The chapter is divided into two broad areas to represent distinct phases of testing involving test development and test application. A model is provided to illustrate the integrated role of testing with measurement and assessment components. Theories of measurement are reviewed with the use of the Item Response Theory, not only for the purpose of objective measurement, but as a basic model to analyze how personal attributes interact with test stimuli. Interpretive phases of tests within an assessment process are described, which include decision-making, prescriptive action, and social outcomes.
