Document Summary

Good item for norm referenced: item for which high scorers respond correctly, low scorers score incorrectly. Same pattern for criterion-oriented, but not what makes item good. Need to meet criteria, not necessarily be first in class, although exceptions. Criterion uses group that have mastered, group that has not to test it. Pilot work: refer to the preliminary research surrounding the creation of a prototype of the test. Scaling: process of setting rules for assigning numbers in measurement. L. l thurstone credit for being creating methodologically sound scaling methods, also introduced absolute scaling, which is procedure for obtaining a measure of item difficulty across samples of testtakers who vary in ability. Aged-based scale, grade-based scale, stanine scale, uni/multidimensional, comparative or categorical. Testtaker presumed to have more or less of the characteristic measured by valid test as a function of the test score.
