Personalized, competency-based learning efforts often take place in a single classroom or school, but not systematically across districts, let alone states. To address this dynamic and increase the scale of personalized, competency-based learning, KnowledgeWorks, an independent nonprofit organization that partners with education stakeholders to advance personalized competency-based learning efforts, has engaged in state level implementation support of personalized, competency-based learning in a number of states, including Arizona, Nevada, North Dakota, and South Carolina. The purpose of this report is to serve as a resource for the states and districts already involved in personalized, competency-based learning, provide considerations for other states adopting personalized, competency-based learning, and offer lessons learned for the wider field. The research team and KnowledgeWorks established three goals for the study at the outset: (1) Document approaches and lessons learned from policy adoption and implementation of personalized, competency-based learning policies in four states; (2) Identify how the COVID-19 pandemic impacted the move towards personalized, competency-based learning in each state; and (3) Identify how each state defines and operationalizes its equity commitment within the state's personalized, competency-based learning efforts.
