Assessing complex constructs such as those discussed under the umbrella of 21st century constructs highlights the need for a principled assessment design and validation approach. In our discussion, we made a case for three considerations: (a) taking construct complexity into account across various stages of assessment development such as the…

This study explores measurement of a construct called knowledge integration in science using multiple-choice and explanation items. We use construct and instructional validity evidence to examine the role multiple-choice and explanation items plays in measuring students' knowledge integration ability. For construct validity, we analyze item…

Methodological procedures used in validating the theoretical structure of academic self-concept and validating associated measurement instruments are reviewed. Substantive findings from research related to modes of inquiry are summarized, and recommendations for future research are outlined. (TJH)

This review of methods for validating writing assessments was conceptualized within a framework suggested by S. Messick (1989) that included five operational components of construct validation: (1) content representativeness; (2) structural fidelity; (3) nomological validity; (4) criterion-related validity; and (5) nomothetic span.

Using S. J. Messick's theoretical work concerning construct validity as a guide, underlying hypotheses for investigation when validating placement test decisions are assessed. Guidelines on validating placement decisions are offered, and the hypotheses and guidelines are applied in a validation study of the Written English Expression Placement…
