This CD-ROM contains data and documentation files for the main 1996 national assessment and the 1996 long-term trend assessments. The national main assessments were conducted for mathematics and science at grades 4, 8, and 12. The long-term trend studies were conducted in reading, mathematics, writing, and science to provide links to results from previous assessments. Included on the CD-ROM is a User's Guide provided in electronic portable document format (PDF). This guide contains information on the contents and use of the data files on this disk as well as the assessment design and its implications for analysis. NAEP datasets from 2002 onward require a Tool Kit with the updated NAEPEX. Your organization must apply for and be granted a restricted-use data license in order to obtain these data.
