The purpose of this overview is to highlight select common elements of state definitions of "college and career readiness." Although preparing students for postgraduation opportunities has long been a priority for states, districts, and schools, a burgeoning global economy and ongoing labor market shifts call for renewed attention to the readiness requirements for student success in this changing postsecondary landscape. The current domestic workforce demands employees who can fill middle-and high-skills jobs that require a combination of technical and academic skills (Carnevale, Smith, & Strohl, 2010). However, employers struggle to find such qualified workers (Organisation for Economic Co-operation and Development, 2013). A definition of college and career readiness can help build an understanding of what these skills are, by highlighting the knowledge, skills, and dispositions of learners who are prepared for postsecondary success. In addition, these definitions can guide educators' efforts to identify which students are on track to succeed in the economy of the 21st century. Recent widespread adoption of the Common Core State Standards or other similar standards in English language arts and mathematics has furthered the conversation about what prepared students look like. The adoption of these standards and the Next Generation Science Standards are designed to set higher expectations for critical thinking, problem-solving, and collaborative skills across a range of academic subjects. As these standards create a set of academic expectations for college and career readiness, definitions of college and career readiness can reinforce these goals and set similar expectations in other areas of student performance. In addition, definitions can play an essential role in guiding states' efforts to achieve their visions for college and career readiness to ensure that students receive the multidimensional preparation necessary for success in the global economy. An appendix entitled, "College and Career Readiness: Actionable State Definitions," is included.
