The Director and Principal shall organize available resources to implement a multi-tiered system of support that uses data-driven problem-solving and research-based instructional practices for all students. The Director and Principal shall establish processes and standards for addressing concerns about student performance and for documenting student responses to research-based instruction and interventions within the MTSS. Using information about the student’s response to instruction and/or interventions and other student performance data, school personnel must identify students at risk of academic failure as early as reasonably may be done, beginning in kindergarten. School administrators and teachers shall address the needs of students identified as at risk of academic failure through the supports available in the MTSS. The parents or guardians of such students should be included, through oral or written communication or other means, in the implementation and review of academic and/or behavioral interventions for their children.
