These training materials were designed to be used by participants at a National Student Loan Data System (NSLDS) workshop which explains how to use the NSLDS Web site. Following an overview, the guide is organized into four sessions: (1) students' access and use of the NSLDS Web site; (2) navigating the financial aid professional Web site; (3) reporting data (data providers and types and timing of data sent to NSLDS); and (4) resolving conflicts (case studies on loan issues, social security number and date of birth issues, and other issues). A wrap-up session, including questions and comments, evaluation of the workshop, and answer keys for sessions 3 and 4 complete the guide. A Training Satisfaction Survey sheet is included. (CH)
