The Common Core of Data (CCD) is an annual collection of public elementary and secondary education data administered by the National Center for Education Statistics (NCES) and its collection agent, the U.S. Census Bureau. Data for CCD surveys are provided by state education agencies (SEAs). This report presents findings on public education revenues and expenditures using fiscal year 2006 (FY 06) data from the National Public Education Financial Survey (NPEFS) of the CCD survey system. Programs covered in the NPEFS include regular, special, and vocational education; charter schools (if they reported data to the SEA); and state-run education programs (such as special education centers or education programs for incarcerated youth). The CCD NPEFS is a universe collection of public elementary and secondary education finance data reported annually by SEAs in each of the 50 states, the District of Columbia, Puerto Rico, and the four other jurisdictions of American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands. The NPEFS provides SEA-level data for all revenues and expenditures associated with each reporting state or jurisdiction, including revenues by source and expenditures by function and object. The nonfiscal data item of average daily attendance is also collected. SEAs participate in the CCD voluntarily, following standard definitions for the data items they report. In some cases, SEAs may be unable to report a key data item or may be unable to report a key data item in exact accordance with a CCD definition. When this happens, NCES imputes or adjusts values for these items. Appendix A, Methodology and Technical Notes, in this report contains a detailed discussion of imputations and adjustments. While the tables in this report include data for all NPEFS respondents, the discussion in the text is limited to the 50 states and the District of Columbia. Data for all of the current expenditure functions collected on NPEFS are presented in tables 2, 3, and 4. These 10 functions are combined to make 4 categories in tables 5 and 6. Appended are: (1) Methodology and Technical Notes; and (2) Common Core of Data Glossary. (Contains 8 tables and 3 figures.)
