NCES 2009003	Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K), Eighth-Grade Methodology Report This methodology report provides technical information about the development, design, and conduct of the eighth grade data collection of the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K). Detailed information on the development of the instruments, sample design, data collection methods, data preparation and editing, response rates, and weighting and variance estimation is included.	9/30/2009
NCES 2009029	An Evaluation of Bias in the 2007 National Households Education Surveys Program: Results From a Special Data Collection Effort The National Household Education Surveys Program (NHES) is a random digit dialing (RDD) survey program developed by the National Center for Education Statistics (NCES) in the Institute of Education Sciences, U.S. Department of Education. The surveys are designed to help NCES collect data directly from households about important education topics. Like many household studies that rely on landline phone sampling frames, NHES has experienced both declining response rates and increasing undercoverage rates. The study described in this report was designed to examine bias in the NHES:2007 due to nonresponse, as well as bias due to noncoverage of households that only had cell phones and households without any telephones. Results from this study suggest that there is no systematic pattern of bias in key statistics from the NHES:2007, though it might underestimate some indicators such as the percentage of preschoolers who watch two or more hours of TV in a typical weekday and overestimate some indicators such as the percentage of preschoolers with mothers who are not in the labor force.	5/12/2009
NCES 2009047	National Household Education Surveys Program of 2007: Methodology Report This report documents the design and collection of the National Household Education Surveys Program (NHES) of 2007. Chapter 1 provides an overview of the collection and the report. Chapter 2 discusses the design of the questionnaires. Chapter 3 presents the sample design. Chapter 4 provides information about the data collection experience. Chapter 5 focuses on unit response rates. Item response rates and imputation are discussed in chapter 6. Chapter 7 contains information about weighting and variance estimation. Chapter 8 provides a summary of bias analyses conducted as part of the study. Chapter 9 provides a comparison of estimates to extant data sources. Chapter 10 summarizes the re-interview study.	4/20/2009
NCES 2007016	Nonresponse Bias in the 2005 National Household Education Surveys Program This report includes assessments of the potential for both unit and item nonresponse bias in the surveys fielded as part of the 2005 National Household Education Surveys Program. The analysis of unit nonresponse bias showed no evidence of bias in the estimates considered from the Early Childhood Program Participation and After-School Programs and Activities Surveys. For the Adult Education Survey, the only evidence of unit nonresponse bias is in estimates of sex: females were more likely to respond than males. The weighting class adjustment for nonresponse should reduce or correct this bias.	3/26/2007
