This report provides the results of a systematic analysis of bias due to the nonresponding persons in the 2003 ALL sample. The ALL estimates of literacy-related skills in the United States are subject to potential bias due to nonresponse at various levels of data collection. The ALL survey estimates of literacy-related skills are subject to unit nonresponse from the screener, background questionnaire (BQ), and assessment, and also subject to item nonresponse to BQ items. The unit analyses were composed of a bivariate analysis, multivariate analysis, and an analysis of the weighting effects on nonresponse bias. The item analyses included a similar study into the effect of nonresponse. The general conclusion of the unit analysis is that the potential amount of nonresponse bias due to unit nonresponse in ALL is likely to be negligible. The item nonresponse analysis revealed some low response rates in certain domains and some indication that a potential for bias may exist.

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.

|NCES 2008346||Education Longitudinal Study of 2002/06: Restricted Use Second Follow-up Data Files, Data File Documentation, and Electronic Codebook System
This ELS:2002/2004 CDROM contains a revised version of the restricted-use base-year to second follow-up data that were previously released. Manuals documenting the sample design of these data, how they were collected, and how they should be used are included. This documentation is public use and can be downloaded directly from the ELS website (http://nces.ed.gov/surveys/els2002 /manuals.asp).
The ELS:2002 longitudinal study is designed to monitor a national sample of young people as they progress from tenth grade through high school and on to postsecondary education and/or the world of work. By the third follow-up in 2012, these young people will be in their mid-twenties.
Users of the original second follow-up restricted-use data (NCES 2008-346) can obtain this revised version (NCES 2008-346r) by requesting it from the IES Data Security Office (IESData.Security@ed.gov). Nearly all of the changes that have been made in the original data are in base year and first follow-up variables and not transcript or second follow-up variables.
However, none of these changes affect data that were originally released in the base year to first follow-up restricted-use data (NCES 2006-430 ), or the transcript restricted-use data (NCES-2006-351).

|NCES 2007044||Trends in International Mathematics and Science Study (TIMSS) 2003 Nonresponse Bias Analysis
This technical report explores the extent of potential bias introduced into the U.S. TIMSS study through nonresponse on the part of schools. Data from the third cycle of TIMSS, conducted in April-June, 2003, are the basis for the analyses. The analyses compare selected characteristics likely to reflect bias in participation from participating and non-participating schools. Two forms of analysis were undertaken: a test of the independence of each school characteristic and participation status, and logistic regression in which the conditional independence of selected school characteristics as predictors of participation was examined. The investigation into nonresponse bias at the school level for U.S. TIMSS 2003 samples for grades 4 and 8 shows that there was no statistically significant relationship detected between participation status and the majority of school characteristics that are available for analysis.

This report is designed to give readers an accurate picture of this important study and the data generated by its methodology. The report is organized into 6 chapters, including information about the purpose of the study, the sample design, the data collection instruments, data collection and data processing procedures, an evaluation of data quality, and weighting and variance estimation. Of the 34,330 eligible sample members, 26,110 (76 percent) completed the faculty questionnaire during a field period from January to October of 2004. Seventy-six percent of respondents completed the self-administered web questionnaire, and 24 percent were interviewed by telephone. The average time to complete the survey was 30 minutes. Of the 1,070 eligible institutions, 980 (91 percent) provided faculty lists and 920 (84 percent) completed the institution questionnaire. Evaluations of operations and procedures focused on the institution contacting endeavor, the timeline for data collection from institutions (faculty lists and institution questionnaires) and faculty (CATI and self-administered interviews), tracing and locating procedures, refusal conversion efforts, the effectiveness of incentives, and the length of the faculty interview. Item nonresponse was below 15 percent for 87 of the 90 items in the institution questionnaire and for 141 out of the 162 items in the faculty questionnaire.

During each of the three school years the Census Bureau also conducted a reinterview of the administrators, schools, and teachers. This report contains the reinterview results from the 1993-94 school year.
