2023 South Carolina Code of Laws › Title 59 - Education › Chapter 33 - Special Education For Handicapped Children › Section 59-33-510. Definitions.

As used in this section:
(1) "Evidence-based reading instruction" means reading, writing, and spelling instruction that employs direct instruction of systematic and cumulative content, with the sequence beginning with the easiest and most basic elements, and progressing methodically to more difficult material. Each step also must be based on steps already learned. Components of evidence-based reading instruction include instruction targeting phonemic awareness, phonics, fluency, vocabulary, and comprehension.
(2) "Dyslexia-specific intervention" means evidence-based, specialized reading, writing, and spelling instruction that is multisensory in nature, equipping students to simultaneously use multiple senses, such as vision, hearing, touch, and movement. Dyslexia-specific intervention requires greater intensity, such as smaller groups, increased frequency of instruction, and individualized progression through steps, than typical evidence-based reading instruction.
(3) "Multi-tiered system of supports" or "MTSS" means an evidence-based model of schooling that uses data-based problem solving to integrate academic and behavioral instruction and intervention. The integrated academic and behavioral supports are delivered to students at varying intensities by means of multiple tiers based on student need. Need-driven decision making seeks to ensure that district resources reach the appropriate students at their schools at the appropriate levels to accelerate the performance of all students to fulfill the profile of the South Carolina Graduate.
(4) "Response to Intervention" or "RTI" means the process of providing high-quality instruction and intervention matched to student needs using learning rate over time and level of performance to make important instructional decisions. To ensure efficient use of resources, schools begin with the identification of trends and patterns using schoolwide data and grade level data. Students who need instructional intervention beyond what is provided universally for positive behavior or academic content areas are provided with targeted, supplemental interventions delivered individually or in small groups at increasing levels of intensity. RTI is a process that is driven by the use of a problem-solving model and is used for the purpose of revealing what works best for groups of students and individual students, regardless of placement.
(5) "Tiered instruction" means instruction and intervention provided with increasing intensity in response to student needs. This instruction is typically provided in an RTI process depicted as a three-tier model. Data is collected at each tier and is used to measure the efficacy of the instruction and intervention so that meaningful decisions may be made about how instruction and intervention should be maintained and layered. Tier 1 is the foundation and consists of scientific, research-based core instructional and behavioral methodologies, practices, and supports designed for all students in the general curriculum. Tier 2 consists of supplemental, targeted instruction and interventions that are provided in addition to and in alignment with effective core instruction and behavioral supports to groups of targeted students who need additional instructional support, behavioral support, or both. Tier 3 consists of intensive instructional or behavioral interventions provided in addition to and in alignment with effective core instruction with the goal of increasing an individual student's rate of progress. Tier 3 interventions are developed for individual students using a problem-solving process. Students receiving Tier 3 level supports may or may not be eligible for specially designed instruction and related services in accordance with the Individuals with Disabilities Education Improvement Act.
(6) "Problem-solving model" means a problem-solving method used to match instructional resources to educational need. The problem-solving model uses data to define the problem, establish performance goals, develop intervention plans, monitor progress, and evaluate outcomes.
(7) "Universal screening process (USP)" means the process a district employs to screen all students who may be experiencing academic and/or social-emotional difficulties. The screening tools and the process must be based on approval and guidelines provided by the department, which must include screening tools that must be administered at no cost to the district.
