This manual is a guide to handling data related to the federal student financial aid program through the electronic data exchange (EDE) system EDExpress. The overview defines how data is exchanged and identifies key players in the exchange of data. The overall process for sending and receiving data is outlined, along with the overall processing schedule, and the role of EDExpress and Edconnect, the computer software provided to institutions participating in the Student Aid Internet Gateway. Schools actually exchange information within five Student Financial Aid processors, and these are described. The second lesson sets forth the basics of EDE processing of student records, and the third explains how to import student data into the system. Lesson 4 discusses identifying records, and lesson 5 explains how to make corrections. Lesson 6 focuses on exporting data. Exercises are included to reinforce the messages of each lesson. (SLD)
