Previously Impossible Feats of Interpretation and Explanation with the Cognitive and Achievement Data

Traditionally, assessment professionals have placed great emphasis on discrepancies between cognitive and academic performance. More recently, finding explanations for these discrepancies has been emphasized (i.e., identifying cognitive processing deficits that are plausible causes of low academic performance). Often these deficits are identified without statistically defensible methods. In this poster, trainers will be shown new methods to explore previously impossible-to-test hypotheses about plausible causes of an individual’s academic problems using a free, downloadable software program called the Compositator. This new software uses multiple regression and path analysis, allowing the user to glean more information from WJ-III (and other) assessment data than was previously possible. Participants will be shown how to create custom composite scores so that all assessment data can be used more efficiently and reliably. More importantly, participants will be shown how to use this software as an informative teaching tool. That is, the use of this software is especially helpful for trainers interested in teaching state-of-the-art assessment methodology and interpretation. It will allow trainers to teach students defensible methods of providing parents and teachers with more plausible and precise explanations of an individual’s academic performance. With these better explanations, this program will also allow for better intervention planning.
