A course in the theory of mental tests

A systematic approach to the construction and evaluation of tests of ability.

“…This thesis is concerned with the first three of these problems, the consistency of a test, the choice of subtests or items, and the unit of measurement. A comparison of the contents of Part I of this thesis with Gulliksen's (14) outline for a course in mental testing, will verify further that these three topics comprise a major and central portion of the theoretical aspects of test construction. The writer believes that precisely these three problems, besides being the major problems in test construction per se, are first problems in the sense that their solution is presupposed by the most powerful instrument of test analysis now available, namely, factor analysis.…”
