ContactCommon Core of Data Survey system. The State Nonfiscal Survey of Public Elementary/Secondary Education, the Local Education Agency Universe Survey, and the Public Elementary/Secondary School Universe Survey are the nonfiscal components of the Common Core of Data (CCD) survey system. These surveys are reported annually by state education agencies (SEAs).
Participation in 2007-08. The data are collected from SEAs through the Department of Education's EDFacts system. The 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands participated in EDFacts for the 2007-08 school year; the Department of Defense dependents schools (overseas and domestic) and the Commonwealth of the Northern Mariana Islands reported directly to the CCD. The Bureau of Indian Education, American Samoa, and Guam did not report data for the 2007-08 school year.
The 2007-08 school year EDFacts collection of CCD data opened in January 2008 and closed in July 2009.
Totals. "United States" and "reporting states" totals in the tables are limited to the 50 states and the District of Columbia. They do not include data from the Bureau of Indian Education, Department of Defense dependents schools (overseas and domestic), Puerto Rico, or the other jurisdictions of American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, or the U.S. Virgin Islands.
Missing data. Not all states collect and report all of the data items requested in the CCD surveys. NCES attempts to correct missing data first by drawing on other sources. For example, a state may be unable to report data during the collection period, but publishes them later, through a written report or website. NCES imports data from these other published sources to correct missing items. NCES will also carry some information, such as address or telephone number, from a prior year's report if it is missing in the current year. (Statistical information, such as the number of students in membership, would not be carried forward.) These procedures are used for any data item, and for all of the three nonfiscal CCD surveys. In 2007-08, the CCD carried forward from prior years the numbers and types of schools for the Bureau of Indian Education, American Samoa, and Guam.
NCES imputes (replaces a nonresponse with a plausible value) some missing items in the State Nonfiscal Survey of Public Elementary/Secondary Education Survey, but does not impute missing items in the Public Elementary/ Secondary School Universe Survey (used in this report) or the Local Education Agency Universe Survey.
When reporting results, NCES treats missing data within individual states differently than it treats missing data across all states and the District of Columbia. An individual state is considered to have missing data if an item is reported for less than 80 percent of possible cases.
If information is missing for some, but no more than 15 percent, of possible cases across the 50 states and District of Columbia, NCES calculates totals and identifies them as "reporting states" totals (rather than totals for the United States). For example, New Jersey reported the magnet status of fewer than 80 percent of the state's schools in 2007-08 (see table 2). Because the schools in New Jersey comprised less than 15 percent of all schools in the United States, the table shows a total for reporting states. Precise information about the extent of missing data is included in the documentation for the Public Elementary/Secondary School Universe Survey 2007-08 file.
EDFacts accepted blank responses in 2007-08 school year reports and did not require that states distinguish among missing, not applicable, and "zero" values. Every effort was made to correctly identify responses as missing, not applicable, or zero after the fact, but it is possible that some blank responses were categorized incorrectly.
Data quality. Staff at NCES, the Census Bureau, and the American Institutes for Research's Education Statistics Service Institute collaborate to edit all CCD data submissions. Data editors ask state CCD coordinators to correct or confirm any numbers that appear out of range when compared with other states' data or with the state's reports in previous years. If no explanation is forthcoming for anomalous data, NCES will change the value (as an example, replace a reported value with the sum of detail) or change it to "not available." For example, if a state's number of 12th-grade students was substantially larger than the number of students in grade 11 in the previous year, and the state could not explain the discrepancy, NCES would change the reported number of 12th-grade students to "not available."
School and agency operational and membership status. In order to ensure continuity over time, the CCD includes schools and agencies that may not be operating during the school year reported. "Inactive" schools are those that are closed temporarily, with the intention that they will be reopened, and they retain their original NCES identification code. "Closed" schools are reported for one year after they have been closed. "Future" schools are those that are scheduled to open, but have not yet begun to operate.
Some operational schools or agencies may legitimately not report students. The CCD allows a student to be reported for only a single school or agency. A vocational school or a local education agency operating only vocational schools may provide classes for students from a number of regular schools or school districts. In this case, the students are usually reported in the membership of their school of record, and the vocational school (identified as a "shared time" school) shows no student membership. It is also possible that an operational school that is not "shared time" can be reported with no membership. For example, the number of students may be missing, or the school could have not yet enrolled students when it was reported.
Reportable programs. Every effort is made to ensure that the CCD and EDFacts files agree in the numbers of schools they contain. Because the EDFacts system collects data for a number of programs in the U.S. Department of Education, it includes some entities that do not meet the CCD's definition of a school. A total of 112 of these entities, referred to as "reportable programs," were excluded from this report.
School type adjustments. Beginning with the 2007-08 school year, the CCD adjusts the reported school type if it does not agree with the CCD definition. For example, although Texas does not identify any of its schools as special education schools, this report indicates that there are 23 special education schools in the state (table 2). If a school name indicated that it focused primarily on the needs of students with disabilities and an examination of the school's associated local education agency revealed that at least 80 percent of the students enrolled had special education individual education programs (IEPs), NCES reclassified the school as a special education school. (The number of students with IEPs is reported at the local education agency level only.) A similar exercise was conducted with schools whose names suggested they were primarily vocational or alternative schools; however, in these cases, the determination was made by researching the school in question via the Internet. State CCD Coordinators were asked to review these reclassifications, and if they provided evidence that a school met the CCD criteria for the reported type, the originally reported school type was not changed.
Agreement across survey levels. Some students receive a public education outside a regular school district (for example, they may attend a state-operated residential school). Some students in a regular school district may not be served by a school. Hospital-homebound students, for example, may be reported in the membership for a regular school district but not for any of the district's schools. The numbers of students and staff shown in the tables for any CCD First Look report are derived from the survey represented in that report. Therefore, the numbers may differ across reports. The numbers reported in the State Nonfiscal Survey of Public Elementary/ Secondary Education are considered the official statistics for a state.
Staff counts. All staff counts (including teachers) are reported in full-time equivalent (FTE) units. This is the amount of time required to perform an assignment stated as a proportion of a full-time position. It is computed by dividing the amount of time an individual is employed by the time normally required for a full-time position.
Locale code changes. The locale codes shown in this report were created using a different methodology than that used to create locale codes prior to 2006-07. The current locale codes are based on newer geographic definitions and describe the location of a school more accurately than was possible using the older system.
