Multi-Tier System of Supports (MTSS)

Under IDEA 2004, states may no longer require school districts to use a discrepancy model (a comparison of a student’s academic achievement and intellectual ability) when determining eligibility for specific learning disabilities (SLD). Furthermore, states must allow (but not require) for the use of “a process based on the child’s response to scientific, research based intervention” or RTI. Lastly, states may also allow the use of other alternative research-based procedures for determining whether a child has SLD.

IDEA federal regulations issued in 2006 require every state to develop criteria for SLD identification that comply with the requirements above. These state-developed eligibility criteria vary significantly across states.

In Kansas RTI is referred to MTSS
