Lifelong Learning Skills (LLS) provide the foundation for learning and working. They broadly support student thinking, self-management, and social interaction, enabling the pursuit of education and career goals. Collectively, LLS are the means by which students master academic content and translate knowledge into action. There is a growing consensus among researchers that LLS are discretely identifiable and actionable levers of support for meeting college and career readiness (CCR) objectives. In an attempt to highlight this, and to consolidate some of the key evidence behind LLS, the College and Career Readiness and Success Center (CCRS Center) at American Institutes for Research has developed an annotated bibliography, which summarizes a broadly applicable and representative sample of LLS research. This executive summary describes uses for the annotated bibliography, highlights key takeaways from the research, provides a sample of LLS assessments, and suggests policy considerations for policymakers and leaders in education.
