  4. NCES U.S. IALS Restricted-Use Data File
    The IALS U.S. 1994 restricted-use file (RUF) with rescaled literacy scores (found here) contains individual unit data including both responses to the background questionnaire and the cognitive assessment from the U.S. IALS data collection, completed in 1994. The file contains rescaled plausible values for literacy and some trend background questionnaire items to allow for trend analysis with the U.S. Program for the International Assessment of Adult Competencies (PIAAC) data. The RUF with rescaled scores can be accessed through a restricted use license agreement with the National Center for Education Statistics.
