In accordance with 23 Illinois Administrative Code 226.130, beginning with the 2010-2011 school year, Illinois districts are required to use a process that determines how a child responds to scientific, research-based interventions as part of the evaluation procedures to determine special education eligibility under the category of specific learning disability (SLD). While this requirement is specific to SLD, districts also have the option of using such a process as part of the evaluation procedures for other disability categories.
