Published empirical evidence for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) does not address some essential questions pertaining to the applied practice of intellectual assessment. In this study, the structure and cross-age invariance of the latest WAIS-IV revision were examined to (a) elucidate the nature of the constructs measured and (b) determine whether the same constructs are measured across ages. Results suggest that a Cattell-Horn-Carroll (CHC)-inspired structure provides a better description of test performance than the published scoring structure does. Broad CHC abilities measured by the WAIS-IV include crystallized ability (Gc), fluid reasoning (Gf), visual processing (Gv), short-term memory (Gsm), and processing speed (Gs), although some of these abilities are measured more comprehensively than are others. Additionally, the WAIS-IV provides a measure of quantitative reasoning (QR). Results also suggest a lack of cross-age invariance resulting from age-related differences in factor loadings. Formulas for calculating CHC indexes and suggestions for interpretation are provided.

We explored relations between reading comprehension performance and self-reported components of metacognition in middle-school children. Students’ self-reported metacognitive strategies in planning and evaluation accounted for significant variance in reading comprehension performance on questions involving inferences. In Study 2, middle school students read a science text then made predictions about how they would perform on a comprehension test. Students’ metacomprehension accuracy was related to their performance at different levels of understanding. Students’ text-based question performance accounted for significant variance in metacomprehension accuracy for text-based questions, and inference-based question performance accounted for significant variance in metacomprehension accuracy for inference-based questions. Results from the two studies suggest that metacognitive and metacomprehension knowledge is aligned with the level of information given in text, and is related to deeper understanding of texts, particularly for inferential information. We discuss the implications of these findings and how future research on absolute metacomprehension accuracy should consider different levels of understanding.

This study examined the identification frameworks, specific models, and assessment practices used by school psychologists to identify students with specific learning disabilities (SLD) in public schools in the United States. We surveyed school psychologist practitioners using an online survey, conducted a review of state regulations addressing SLD, and evaluated the effects of state-level policies and school psychologists' characteristics on identification practices. Responses from more than 1,300 school psychologists revealed that multiple SLD identification frameworks are utilized and that state regulations generally have stronger effects on identification practices than do characteristics such as school psychologists' age, highest degree obtained, and years of experience. Frameworks with well-known psychometric limitations, such as those employing intelligence-achievement discrepancy formulas, remain commonly employed. We encourage more and better scientific research into both the conceptual and psychometric outcomes associated with SLD identification frameworks and urge application of evidence-based practices in the assessment and treatment of academic deficits.
