Changes that have been made in reporting and disseminating information from the National Assessment of Educational Progress are discussed, focusing on those changes brought about by the first Trial State Assessment (TSA). The TSA collected data on the mathematics performance of students in grades 4, 8, and 12 in public and private schools in 40 states. This voluminous material was not well-digested by the media or the public. In contrast, briefer and more focused reports on science achievement and writing achievement were more enthusiastically received and more readily used. The National Center for Education Statistics (NCES) then developed a two-part plan for data release. Part 1 involved data release in smaller portions, and part 2 consisted of improvement of the data presentation. These improvements were initiated with a conference of measurement professionals who planned new comparison charts and better ways of formatting the information. Five figures illustrate some of the new approaches. (SLD)
