Multitiered systems of support (MTSS) is a system of targeted support for students struggling academically or behaviorally. MTSS is considered to be a pre–special education process in which students receive targeted interventions to address areas of need, which are evaluated to determine if the students are responding to the intervention or making progress towards a goal. When implemented in preschool, MTSS aids in early identification of at-risk students, minimizes inappropriate special education referrals, and remediates potential delays affecting school readiness and later learning or social–emotional outcomes (Greenwood et al., 2019).
