The National Forum on Education Statistics (Forum) organized the College and Career Ready (CCR) Working Group to explore how state and local education agencies (SEAs and LEAs) can use data to support college and career readiness initiatives. The working group determined that high-quality data in integrated K12, postsecondary, and workforce data systems can be of value to all CCR stakeholders when they are used to: (1) foster individualized learning for students; (2) support educators in identifying and addressing student-specific needs; (3) measure progress made by education agencies in achieving CCR accountability and continuous improvement goals; and (4) maximize career opportunities for all students. Through the presentation of five data use cases related to these goals, this document can serve as a practical guide for determining the appropriate data elements, metrics, and reporting tools needed to support specific CCR initiatives within SEAs and LEAs. A list of references and resources is appended.
