The "Forum Guide to Exit Codes" provides an updated taxonomy for exit codes, information on best practices related to exit coding, and case studies that highlight different education agencies' approaches to and experiences with exit coding. In 2006, the Forum addressed the need for a voluntary, common format for tracking data about when students transferred, completed high school, dropped out, or otherwise exited an education agency with the publication of "Accounting for Every Student: A Taxonomy for Standard Student Exit Codes." This new publication updates information originally published in the 2006 document. This resource is intended for education agency leaders and staff who collect and use data on student enrollment and exit status to accurately account for all students. This resource includes the following chapters and appendices: (1) Introduction to Exit Codes; (2) The Exit Codes Taxonomy; (3) Best Practices in Exit Coding; (4) Case Studies; and (5) Characteristics of Sound Exit Code Taxonomies.
