In this article, we discuss the use of administrative data from schools, colleges and universities, and other public and private agencies and organizations for tracking students through their educational pathways. We focus on existing data collection systems that can be used to study successful postsecondary education transitions, including both statewide and local initiatives. We describe in detail the Youth Data Archive, which combines administrative data from multiple public and private agencies and organizations on a local level to ask and answer community questions about the youth they serve.
