Preschool-aged children with or at risk for attention deficit hyperactivity disorder (ADHD) experience significant challenges with behavioral, social, and preacademic skills. We conclude that interchanging MSEL and DAS-II scores without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution.

The purpose of this study was to determine whether distinct subgroups of children with learning disabilities could be identified using a single, recently developed instrumentthe Differential Ability Scales (DAS). Concerns about the ability-achievement discrepancy method for specific learning disability (SLD) determination led to alternative research-based methods, such as failure to respond to intervention.
