The present article gives an overview of several studies on the predictive validity of the C-test. In the first part of the article, we discuss the construct validity of this test format. Only if the underlying construct of this test is understood, can a justification for high predictive validity be made. In the second part, we discuss several…

Although there have been numerous studies investigating the predictive validity of early assessment, observed predictive validity coefficients across studies are not stable. A validity generalization study was conducted in order to answer the question of whether the relationship between early assessment of children and later achievement is…

The idea that validity should be considered a property of inferences, rather than of assessments, has developed slowly over the past century. In early writings about the validity of educational assessments, validity was defined as a property of an assessment. The most common definition was that an assessment was valid to the extent that it…
