The theory of educational measurement presented in this book has mainly to do with such things as the construction of tests and scales, the types of pupil preformances susceptible of measurement, the meanings of scores and norms, the validation of testing instruments, and the technique of the application. The material has been subjected to new organization, classification, definition, and critical interpretation. The result is a very intelligible treatment of questions that test makers and test users desire very much to understand.
