The Development and Applied Utility of a Normative Aptitude-Achievement Taxonomy for the Woodcock-Johnson Psycho-Educational Battery-Revised.

This study developed a normative core profile taxonomy of the four scholastic aptitude and corresponding achievement scales of the Woodcock-Johnson Psycho-Educational Battery (Revised). Cluster analysis was used to sort 2,620 students from the standardization sample. Results of internal and external validity analyses provided support for eight core profiles. Results suggest methods of evaluating students for learning disabilities. (Author/DB)
