Releasing CCD Nonfiscal Data

May 31, 2023 NCES Blog Editor FAQs, General Share on TwitterShare on FacebookShare on Google+

The Common Core of Data (CCD) contains basic information on public elementary and secondary schools, local education agencies (LEAs), and state education agencies (SEAs) in the United States. The CCD collects fiscal and nonfiscal data about all public schools, public school districts, and state education agencies in the United States. Both IPEDS and CCD provide a sampling frame to many survey collections, including many conducted by NCES and the Department of Education. This blog post, one in a series of posts about CCD nonfiscal data, focuses on CCD’s two major releases and their corresponding components. For information on how to access and use CCD data, read the blog post Accessing the Common Core of Data (CCD).
 

Data Releases

CCD nonfiscal data are published in two releases every school year—as preliminary files and as provisional data files—within the CCD Data File tool. Understanding the differences between the two releases is important to understand how CCD nonfiscal data are released.

  • The preliminary files contain basic information about schools and districts, such as name, address, phone number, status, and NCES ID number. Many schools and districts utilize information from the directory file, such as the NCES ID, to apply for grants or other opportunities for their schools. Therefore, it is important that these files are released first, even if the data are still preliminary. 
     
  • The provisional data files are the full release of the CCD nonfiscal data. These data files provide school-, district-, and state-level data on topics like enrollment, staffing, and free or reduced-price lunch. These files are much more detailed and include data that are broken down by characteristics such as grade, race/ethnicity, and gender—as well as by combinations of these characteristics. These files are not updated unless there is a significant change to the data.

Each file release includes a version that indicates the type of release. The first preliminary files have “0a” in the file names, and revised preliminary files include “0b,” “0c,” and so on. The first provisional files have “1a,” in the file names, and revised provisional files include “1b,” “1c,” and so on. Note, however, that releasing revised files is rare.
 

Components of a Release

It is important to utilize the various components that accompany each release to find additional information that is specific to the file and can help you better understand the data. In addition, there are other resources available that provide more ways to access and understand the data.
 

Documentation Components

Every data file will have documentation files that provide information about the data. These include the following:

  • release notes—basic information about the data release, including details about any changes to the files, such as a change in a variable’s description or a variable that was added to the file; summary tables that include national totals and tables with selected frequencies are also included.
     
  • state data notes—information on data anomalies that are discovered during NCES’s collaboration with the states; broken down by state and by file type, these notes describe things like changes to how data were collected by the state.
     
  • companion files—included in each data file component, these files include a list of all the variables in the data file—including a brief description—and frequency tables; you should start with the companion files to better understand what variables are in each data file.

Resources and Tools

Along with the release of the CCD nonfiscal data files, additional resources are also updated to improve access to the data.

  • Summary Tables: Released with the provisional data files, Summary Tables provide a national-level look at the data. These tables show the operational status of schools and districts by type as well as the number of schools, students, and teachers by state.
     
  • Locators and ElSi: There are two primary tools that can be used to access CCD data: the Locators (School Locator and District Locator) and the Elementary/Secondary Information System (ElSi). These tools are updated as the data files are released. The Locators are updated with each release, while ElSi is updated with the release of the provisional data files. Learn more about these tools.
     
  • Online Documentation: The online documentation provides some general information about CCD. This information is not year specific, but it provides a detailed explanation about how the data are collected, processed, and reviewed.
  • Reference Library: The reference library includes detailed documentation on various components of the CCD files that applies to multiple years, levels, and components of the data collection. The library includes crosswalks, documentation describing changes to the collection, and guidance for utilizing the data files, such as how to aggregate free or reduced-price lunch data.

Changes in Pupil/Teacher Ratios in 2020: Impacts of the COVID-19 Pandemic

April 20, 2022 NCES Blog Editor Share on TwitterShare on FacebookShare on Google+

The COVID-19 pandemic has brought enormous challenges to the education system, including a historic decline in enrollment in fall 2020—the largest since during World War II. Due to the relatively small decrease in the number of teachers, there was a significant drop in the pupil/teacher ratio.  

The National Center for Education Statistics (NCES) releases key statistics, including school staffing data, compiled from state administrative records through the Common Core of Data (CCD). In 2019, about 48 percent of public school staff were teachers (3.2 million) and 13 percent were instructional aides (0.9 million). NCES’s new School Pulse Panel survey found that in January 2022, about 61 percent of public schools with at least one vacancy reported that the pandemic increased the number of teacher and staff vacancies, and 57 percent of schools with at least one vacancy found that the pandemic forced them to use teachers outside their normal duty areas.

Pupil/teacher ratios provide a measure of the quantity of instructional resources available to students by comparing the number of students with the total full-time equivalent (FTE) of all teachers, including special education teachers. The public and private elementary and secondary average class size is larger than the pupil/teacher ratio since it normally does not factor into team teaching, specialty teachers, or special education classes. Between fall 2019 and fall 2020, enrollment in public elementary and secondary schools1 decreased by 2.7 percent.2 This decrease was larger than the 0.2 percent (6,700)3 decrease in the number of public school teachers. Since fall 2020, public school enrollment decreased by a larger amount than did the number of teachers. Thus, the pupil/teacher ratio declined in school year 2020–21 by a relatively large 0.5 pupils per teacher, from 15.9 to 15.4 pupils per teacher (figure 1). This is the largest 1-year decrease in more than 4 decades. In comparison, the pupil/teacher ratio for private schools was 11.4 in 2019–20 (the latest year of actual data available). It is worth noting that pupil/teacher ratios vary across schools with different characteristics (table 208.10).

Viewed over a longer term, the pupil/teacher ratio in public schools in 2019–20 (15.9) was only slightly lower than in 2010–11 (16.0), so nearly all the change during the 2010–11 to 2020–21 period occurred in the last year. The pupil/teacher ratio for private schools decreased from 12.5 in 2010–11 to 11.4 in 2019–20.

Line graph showing pupil/teacher ratio in public and private elementary and secondary schools from 2010–11 to 2020–21

NOTE: Data in this figure represent the 50 states and the District of Columbia. Data for teachers are expressed in full-time equivalents (FTE). Counts of private school enrollment include prekindergarten through grade 12 in schools offering kindergarten or higher grades. Counts of private school teachers exclude teachers who teach only prekindergarten students. Counts of public school teachers and enrollment include prekindergarten through grade 12. The pupil/teacher ratio includes teachers for students with disabilities and other special teachers, while these teachers are generally excluded from class size calculations. Ratios for public schools reflect totals reported by states and differ from totals reported for schools or school districts.  The school year 2020–21 pupil/teacher ratio shown in this figure includes only states which reported both membership and FTE teacher counts for SY 2020–21.

SOURCE: U.S. Department of Education, National Center for Education Statistics, Digest of Education Statistics 2021, table 208.20; Common Core of Data, table 2.

The declines in pupil/teacher ratios in public schools were not consistent across states between 2019–20 and 2020–21 (figure 2). The relatively large enrollment decreases in many states—along with the smaller decreases or even increases in the number of teachers in fall 2020—led to decreases in the pupil/teacher ratios for most states. Three states (Nevada, Florida, and Ohio) reported increases in their pupil/teacher ratios, and the rest of the states reporting data had decreases in their pupil/teacher ratios. The states with the largest decreases in their pupil/teacher ratios were Indiana (-1.3 pupils per teacher), Arizona (-1.1 pupils per teacher), Kansas (-0.9 pupils per teacher), and Kentucky (-0.9 pupils per teacher).4

[1] Counts of public school teachers and enrollment include prekindergarten through grade 12.

[2] Enrollment data are for fall of the school year while pupil/teacher ratios are based on school years.

[3] Includes imputed teacher FTE data for Illinois and Utah.

[4] Although Oregon had a 2 pupil per teacher decrease based on the Summary Table 2 for 2019–20 and 2020–21, Oregon did not submit prekindergarten data for 2020–21, so the ratios were not comparable.

New Data Reveal Public School Enrollment Decreased 3 Percent in 2020–21 School Year

July 26, 2021 NCES Blog Editor Datasets, Findings, General Share on TwitterShare on FacebookShare on Google+

NCES recently released revised Common Core of Data (CCD) Preliminary Files, which are the product of the school year (SY) 2020–21 CCD data collection. CCD, the Department of Education’s primary database on public elementary and secondary education in the United States, provides comprehensive annual data on enrollment, school finances, and student graduation rates.

Here are a few key takeaways from the newly released data files:

Public school enrollment in SY 2020–21 was lower than it was in SY 2019–20.

Overall, the number of students enrolled in public schools decreased by 3 percent from SY 2019–20 to SY 2020–21. Note that Illinois did not submit data in time to be included in this preliminary report. The SY 2019–20 and SY 2020–21 total enrollment counts for California, Oregon, American Samoa, and the Bureau of Indian Education do not include prekindergarten counts.

The rate of decline in public school enrollment in SY 2020–21 was not consistent across all states.

Within states, the largest decreases were in Mississippi and Vermont (5 percent each), followed by Washington, New Mexico, Kentucky, New Hampshire, and Maine (each between 4 and 5 percent) (figure 1). Eighteen states had decreases of 3 percent or more; 29 states had decreases between 1 and 3 percent; and the District of Columbia, South Dakota, and Utah had changes of less than 1 percent.

Lower grade levels experienced a greater rate of decline in public school enrollment than did higher grade levels in SY 2020–21.

Public school enrollment decreased by 13 percent for prekindergarten and kindergarten and by 3 percent for grades 1–8. Public school enrollment increased by 0.4 percent for grades 9–12.

Most other jurisdictions experienced declines in public school enrollment in SY 2020–21.

Public school enrollment decreased in Puerto Rico (6 percent), Guam (5 percent), and American Samoa (2 percent). The Virgin Islands, however, experienced an increase of less than 1 percent.

National Spending for Public Schools Increases for the Sixth Consecutive Year in School Year 2018–19

June 15, 2021 NCES Blog Editor Findings, General Share on TwitterShare on FacebookShare on Google+

NCES just released a finance tables report, Revenues and Expenditures for Public Elementary and Secondary Education: FY19 (NCES 2021-302), which draws from data in the National Public Education Financial Survey (NPEFS). The results show that spending1 on elementary and secondary education increased in school year 2018–19 (fiscal year [FY] 2019), after adjusting for inflation. This is the sixth consecutive year that year-over-year education spending increased since 2012–13. This increase follows declines in year-over-year spending for the prior 4 years (2009–10 to 2012–13).

Current expenditures per pupil2 for the day-to-day operation of public elementary and secondary schools rose to $13,187 in FY19, an increase of 2.1 percent from FY18, after adjusting for inflation (figure 1).3 Current expenditures per pupil also increased over the previous year in FY18 (by 0.9 percent), in FY17 (by 1.7 percent), in FY16 (by 2.8 percent), in FY15 (by 2.7 percent), and in FY14 (by 1.2 percent). In FY19, education spending was 11.8 percent higher than the lowest point of the Great Recession in FY13 and 6.1 percent higher than spending prior to the Great Recession in FY10.

Figure 1. National inflation-adjusted current expenditures per pupil for public elementary and secondary school districts: FY10 through FY19

NOTE: Spending is reported in constant FY19 dollars, based on the Consumer Price Index (CPI).
SOURCE: U.S. Department of Education, National Center for Education Statistics, Common Core of Data (CCD), "National Public Education Financial Survey," fiscal years 2010 through 2018 Final Version 2a; and fiscal year 2019, Provisional Version 1a; and Digest of Education Statistics 2019, retrieved January 8, 2021, from https://nces.ed.gov/programs/digest/d19/tables/dt19_106.70.asp.

Without adjusting for geographic cost differences, current expenditures per pupil ranged from $7,950 in Utah to $24,882 in New York (figure 2). In addition to New York, current expenditures per pupil were highest in the District of Columbia ($22,831), New Jersey ($21,331), Vermont ($21,217), and Connecticut ($21,140). In addition to Utah, current expenditures per pupil were lowest in Idaho ($8,043), Arizona ($8,773), Nevada ($9,126), and Oklahoma ($9,203).

[1] Spending refers to current expenditures. Current expenditures comprise expenditures for the day-to-day operation of schools and school districts for public elementary/secondary education, including expenditures for staff salaries and benefits, supplies, and purchased services. Current expenditures include instruction, instruction-related support services (e.g., social work, health, psychological services), and other elementary/secondary current expenditures but exclude expenditures on capital outlay, other programs, and interest on long-term debt.
[2] Per pupil expenditures are calculated using student membership derived from the State Nonfiscal Survey of Public Elementary/Secondary Education. In some states, adjustments are made to ensure consistency between membership and reported fiscal data. More information on these adjustments can be found in the data file documentation at https://nces.ed.gov/ccd/files.asp.
[3] In order to compare spending from one year to the next, expenditures are converted to constant dollars, which adjusts figures for inflation. Inflation adjustments utilize the Consumer Price Index (CPI) published by the U.S. Department of Labor, Bureau of Labor Statistics. For comparability to fiscal education data, NCES adjusts the CPI from a calendar year to a school fiscal year basis (July through June).
