This CD-ROM contains data and documentation files for the main 1994 national assessment and the 1994 long-term trend assessments. The national main assessments were conducted for reading, geography, and U.S. history 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. A User's Guide is provided in electronic portable document format (PDF). This document contains information on the contents and use of the data files 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.
