The purpose of this data guide is to provide users of the National Household Education Survey (NHES) data with suggested techniques for working with the data files. Special attention is paid to topics that will help users avoid the most commonly made mistakes in working with NHES data. The NHES is a data collection system developed by the National Center for Education Statistics to provide descriptive data on the educational activities of the U.S. population. It offers policymakers, researchers, and educators a variety of statistics on the condition of education in the United States. The NHES is a telephone survey of the noninstitutionalized population of the United States for which households are selected through random digit dialing methods. The methodology for any single fielding of the NHES is linked to the research issues under study, the level of data required to address the issues, and how precise the estimates generated from the survey data need to be in order to meet study objectives. Topics addressed by NHES:91 through screening about 60,000 households were early childhood education and adult education. NHES:93 screened about 64,000 households about school readiness and school safety and discipline. The two survey components of NHES:95, early childhood program participation and adult education, paralleled NHES:91 with over 45,000 households. Three appendixes present information about commonly asked questions, data examples, and weighting and sample variance estimation. (Contains 13 appendix tables and 10 references.) (SLD)
