In Portugal the field of Specific Learning Disabilities is characterized by a lack of a technically adequate system of school-wide screening and progress monitoring (Martins, 2006). Emphasis on the need of this system has increased as a result of national research (i.e., Mourão, 2011; Patrão, 2010) within the context of a Multi-level Prevention System. Additionally, Portuguese educational theorists who teach, research, conduct clinics, and write about specific learning disabilities, also documented this need (Martins, 2006).info:eu-repo/semantics/publishedVersio
