The 2011 NAA national Core Knowledge and Competencies (CKCs) have been revised in 2021 with an eye toward equity and culturally responsive practices. The retitled Core Knowledge, Skills, and Competencies (CKSCs) reflect updated research and best practices in promoting equity, inclusion, access, and antiracism in youth work. There are 10 content areas, which each have a rationale, as well as skills and competencies that are grouped into three categories: identify, apply, and amplify. The 2019 companion self-assessment tools and guide on practices that support effective social-emotional learning can be found at SEL to the Core: Building from Foundational Youth Development to Support Social and Emotional Learning.
