Post 1: Specific learning disability (SLD) is a disability category included in the federal definition of educational disabilities. A learning disability is a disorder that generally includes the inability to use or understand language sufficiently enough to learn core academic subjects like reading, writing, or mathematics. The best practices for the identification, classification, and support of students in need of SLD services have been the focus of considerable research over the past century. The evidence-based practices schools have chosen to assess students who are at risk and identify SLD have ranged from the evaluation and comparison of test scores to more subject interventions and psychological assessments. As research uncovers more data regarding learning, each generation tries to improve how students are identified and classified (Fletcher, Stuebing, Morris, & Lyon, 2013). Currently, Multitiered system of supports (MTSS) is widely used in K-12 schools in the United States to identify and support students receiving SLD services. MTSS was intended to help all students by using a multifaceted approach to identifying students at risk or simply in need of additional support to be successful in a specific subject. MTSS includes evidence-based response to intervention (RTI) procedures (Barrett & Newman, 2018). Barrett & Newman (2018) evaluated the effectiveness of MTSS for the identification and classification of students in special education departments serviced under the SLD label as well as the level of achievement attained over a period of ten years. Examining MTSS Implementation Across Systems for SLD Identification: A Case Study describes the effect of MTSS implementation on the identification and achievement of students in a midwestern regional educational service agency (RESA). The authors found that a significant body of research conducted in local schools showed improvement in academic achievement and student behavior when MTSS or RTI frameworks were implemented. Decreases in special education placements and less misclassification of learning disabilities were also significant (Barrett & Newman, 2018). However, these positive findings were shown to be incomplete or inaccurate by a recent nationwide study conducted across 13 states by the Department of Education (2015). This study revealed either a negative or neutral effect of MTSS on students. Referencing this seemingly contradictory data, Barrett and Newman (2018) recognize that one evidence-based approach is insufficient to meet the multifaceted and individual needs of students. The authors suggest that the reliance on IQ test and achievement test discrepancies, or an attempt to identify an SLD through a series of interventions are inadequate. There are a multitude of factors .
