Behavioral Modification and Social-Emotional Learning Frameworks in Pre-Kindergarten Settings: A Scoping Review of the Literature

Ask any Pre-K teacher what the hardest part of their day is, and the answer is rarely the lesson plan. It is almost always a child — or several — whose behavior has derailed instruction, exhausted the classroom, and left the teacher wondering what they missed. This is not a story about bad children or overwhelmed teachers. It is a story about a missing system. Pre-Kindergarten behavioral disruption has reached levels that federal data now describes as a national crisis, with expulsion rates three times higher than K-12 and mounting evidence that children from underserved communities bear the heaviest weight of this failure. And yet, despite years of research investment in social-emotional learning and behavioral intervention, nobody has built the specific thing that Pre-K classrooms actually need: a framework that is tiered, data-generating, somatically grounded, and fully operational even when the lead teacher is absent. This scoping review set out to map what the literature actually contains on this topic. Following PRISMA-ScR guidelines, I searched Google Scholar, ERIC, PsycINFO, and CINAHL for peer-reviewed studies published between 2000 and 2024 examining behavioral modification and SEL frameworks for children aged 3 to 5. What I found confirmed a pattern that any experienced Pre-K educator would recognize: plenty of good individual pieces, but no single framework that puts them together in a way that works in the real world. The review identifies four specific structural gaps — the absence of MTSS-tiered architecture integrated with a Pre-K SEL curriculum, the lack of a simple educator-operated quantifiable rubric, the neglect of somatic regulation instruction calibrated for 3-5 year olds, and the near-universal absence of substitute-teacher-ready protocols. Together these gaps define exactly what a new framework needs to be. The implications for curriculum development, equity, and national early childhood policy are discussed.
