The data were collected via mailed questionnaires with telephone and field follow-up. The first questionnaires were mailed in September 2007, and data collection ended in June 2008. The unit response rates varied from 72 percent for private school principals to 88 percent for public school districts (appendix table B-1 shows the unit and overall response rates for each survey). Nonresponse bias analyses were performed when survey response rates for major reporting groups were less than 85 percent. For information about bias analysis results, methodology, and design of the 2007-08 SASS, please see the technical notes of this report in appendix B and the Documentation for the 2007-08 Schools and Staffing Survey (Tourkin et al. forthcoming).

Because the purpose of First Look reports is to introduce new data, it is possible to only include a small selection of the information in the survey. This First Look report highlights findings from SASS’s district survey. Findings from the school, principal, teacher, and library media center data files will be presented in four companion First Look reports:

  • Characteristics of Public, Private, and Bureau of Indian Education Elementary and Secondary Schools in the United States: Results From the 2007–08 Schools and Staffing Survey (NCES 2009-321);

  • Characteristics of Public, Private, and Bureau of Indian Education Elementary and Secondary School Principals in the United States: Results From the 2007–08 Schools and Staffing Survey (NCES 2009-323);

  • Characteristics of Public, Private, and Bureau of Indian Education Elementary and Secondary School Teachers in the United States: Results From the 2007–08 Schools and Staffing Survey (NCES 2009-324); and

  • Characteristics of Public and Bureau of Indian Education Elementary and Secondary School Library Media Centers in the United States: Results From the 2007–08 Schools and Staffing Survey (NCES 2009-322).

The tables in this report contain counts and percentages demonstrating bivariate relationships between variables. All of the results have been weighted to reflect the sample design and to account for nonresponse and other adjustments. Comparisons drawn in the selected findings have been tested for statistical significance at the .05 level using Student’s t statistics to ensure that the differences are larger than those that might be expected due to sampling variation. No adjustments were made for multiple comparisons. Many of the variables are related to one another, and complex interactions and relationships have not been explored. Statistical Analysis Software (SAS) (9.1) and SUDAAN (10.0) were used to compute the statistics for this report.
