Although approximately 5–8% of students have a mathematical learning disability (MLD), researchers have yet to develop a consensus operational definition. To examine how MLD has been identified and what mathematics topics have been explored, we conducted a systematic review of 164 studies on MLD published between 1974 and 2013. Findings indicate that (a) there was great variability in the classification methods used, (b) studies rarely reported demographic differences between the MLD and typically achieving groups, and (c) studies overwhelmingly focused on elementary–aged students engaged in basic arithmetic calculation. To move the field toward a more precise and shared definition of MLD, we argue for standards for methodology and reporting, and we identify a need for research addressing more complex mathematics.

Mathematical learning disability (MLD) research often conflates low achievement with disabilities and focuses exclusively on deficits of students with MLDs. In this study, the author adopts an alternative approach using a response-to-intervention MLD classification model to identify the resources students draw on rather than the skills they lack. Detailed diagnostic analyses of the sessions revealed that the students understood mathematical representations in atypical ways and that this directly contributed to the persistent difficulties they experienced. Implications for screening and remediation approaches are discussed.
