Calibration And Derivation Of Reference Norms

In this section, several psychometric characteristics of test construction are described as they relate to building individual scales and developing appropriate norm-referenced scores. Calibration refers to the analysis of properties of gradation in a measure, defined in part by properties of test items. Norming is the process of using scores obtained by an appropriate sample to build quantitative references that can be effectively used in the comparison and evaluation of individual performances relative to typical peer expectations.
