NAEP 1990 National and Long-Term Trend Assessments Restricted-Use Data Files

This dataset contains data and documentation files for the 1990 national main assessments and the bridge assessments. The national main assessments were conducted for reading, mathematics, and science at ages 9, 13, and 17, and the corresponding modal grades 4, 8, and 12. The bridge studies were conducted at the same ages/grades in reading, mathematics, writing, and science to provide links to results from previous assessments. Included on the dataset 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.
