An overview chapter defines terms for processing financial aid applications through EDE, explains the seven-step process for sending and receiving data using EDE, and describes good practices for setting up and implementing EDE. Chapter 2 explains features which establish codes and default operating parameters for global EDExpress functions, as well as general navigation and Windows system issues. Chapter 3 explains the creation and use of query and document-tracking functions in EDExpress. Chapters 4 and 5 detail the process of entering data from the Free Application for Federal Student Aid (FAFSA) in the EDExpress application processing module for the purpose of transmitting FAFSA data to the Central Processing System. Chapter 6 explains the procedural steps involved in transmitting and tracking data using the EDconnect telecommunications package. Chapters 7 and 8 then consider the importation of processed Institutional Student Individual Records (ISIRs), management and correction of records in the ISIR database, and development of ISIR reports. Many examples of computer screens illustrate the procedures. Sample printouts of records are appended. (DB)
