Abstract
The K-ABC is examined within the setting of contemporary ability testing, with particular attention to the evolution of current psychometric concepts and methods, as well as the historical sources of popular misconceptions. The discussion focuses on five key questions relevant to test construction and to the interpretation of test results : what intelligence tests measure, the effects of training on the development of intelligence, cultural differences in the meaning of intelligence, how to construct valid tests, and the differentiation between aptitude and achievement testing. When examined in this light, the K-ABC reveals sophisticated application of current test construction methodology.
