Introduction to Learning Disorders
Learning Disorders are diagnosed when a student’s achievement in particular areas of learning (such as spoken or written language, mathematics abilities, etc.), as measured by formal and standardized tests of academic achievement) are significantly less well developed than would be expected given that students’ intelligence (as measured by a formal and standardized test of intelligence), and grade level. Formal subtypes of learning disorder (as documented in the Diagnostic and Statistical Manual of Mental Disorders, the clinician’s diagnostic bible) include: Reading Disorder, Mathematics Disorder, and Disorder of Written Expression. As with most disorder families, a ‘not otherwise specified’ catchall category is made available so that cases that don’t quite fit the established categories can be described.
