Equity is the consistent thread that runs through major California education policies of the last decade, which have focused on providing access and opportunity tailored to students' needs in order to reduce disparities in learning outcomes. Equity challenges, already significant prior to COVID-19, have been exacerbated by the pandemic's education disruptions. Multi-Tiered System of Supports (MTSS) offers a framework for identifying students who are struggling and who need focused support to meet academic, behavioral, and social-emotional challenges. How can California make MTSS implementation more accessible to school districts as they strive to support all students equitably? From 2018 to 2020, Pivot Learning led a demonstration project involving the Sanger, Monterey Peninsula, and Lancaster school districts. Sanger has coherently and cohesively implemented MTSS in a way that adapts the framework to the district's culture. The Pivot-led project, with Monterey and Lancaster as pilot sites, sought to determine if direct support by Sanger, based on its expertise, could help Monterey and Lancaster develop their own district-relevant MTSS implementation strategies. This study combines previous research about Sanger's education improvement efforts with data from the Pivot-Sanger MTSS Project to identify a set of lessons learned that might help guide the state's continued expansion of MTSS.
