An Evaluation of Bias in the 2007 National Household 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 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.
