The National Assessment of Educational Progress, 2009 (NAEP 2009) is a study that is part of the National Assessment of Educational Progress (NAEP) program; program data is available since 1990 at . NAEP 2009 (https://nces.ed.gov/nationsreportcard/) is a cross-sectional survey that assesses what America's students know and can do in various subject areas. The study was conducted using computer-based assessment of students. Students in grades 4, 8, and 12 were sampled. NAEP 2009 assessments consist of national and state assessments in reading and math, at grades 4 and 8; a national and state sample in writing at grade 8; and a national only writing sample at grade 12. The study's response rates were between 83 and 100 percent. Key statistics produced from NAEP 2009 are results on subject-matter achievement, instructional experiences, and school environment for populations of students (e.g., all fourth-graders) and groups within those populations (e.g., female students, Hispanic students).

About the Digest of Education StatisticsThe 2022 edition of the Digest of Education Statistics is the 58th in a series of publications initiated in 1962. The Digest has been issued annually except for combined editions for the years 1977–78, 1983–84, and 1985–86. Its primary purpose is to provide a compilation of statistical information covering the broad field of American education from prekindergarten through graduate school. The Digest includes a selection of data from many sources, both government and private, and draws especially on the results of surveys and activities carried out by the National Center for Education Statistics (NCES). To qualify for inclusion in the Digest, material must be nationwide in scope and of current interest and value. The publication contains information on a variety of subjects in the field of education statistics, including the number of schools and colleges, teachers, enrollments, and graduates, in addition to data on educational attainment, finances, federal funds for education, libraries, and international comparisons. Supplemental information on population trends, attitudes on education, education characteristics of the labor force, government finances, and economic trends provides background for evaluating education data. The Digest contains important information on federal education funding, though more detailed information on federal activities is available from federal education program offices.The Digest contains tables organized into seven chapters: All Levels of Education, Elementary and Secondary Education, Postsecondary Education, Federal Funds for Education and Related Activities, Outcomes of Education, International Comparisons of Education, and Libraries and Use of Technology. Each chapter is divided into a number of topical subsections.About this DatasetThis dataset represents the tables from the Most Current Digest Tables page: https://nces.ed.gov/programs/digest/current_tables.asp, as downloaded 2025-07-13.The folder system has three levels.

The 2020-2021 School Learning Modalities dataset provides weekly estimates of school learning modality (including in-person, remote, or hybrid learning) for U.S. K-12 public and independent charter school districts for the 2020-2021 school year, from August 2020 – June 2021.

These data were modeled using multiple sources of input data (see below) to infer the most likely learning modality of a school district for a given week. These data should be considered district-level estimates and may not always reflect true learning modality, particularly for districts in which data are unavailable. If a district reports multiple modality types within the same week, the modality offered for the majority of those days is reflected in the weekly estimate. All school district metadata are sourced from the https://nces.ed.gov/ccd/files.asp#Fiscal:2,LevelId:5,SchoolYearId:35,Page:1">National Center for Educational Statistics (NCES) for 2020-2021.

School learning modality types are defined as follows:

• In-Person: All schools within the district offer face-to-face instruction 5 days per week to all students at all available grade levels.
• Remote: Schools within the district do not offer face-to-face instruction; all learning is conducted online/remotely to all students at all available grade levels.
• Hybrid: Schools within the district offer a combination of in-person and remote learning; face-to-face instruction is offered less than 5 days per week, or only to a subset of students.

Data Information

• School learning modality data provided here are model estimates using combined input data and are not guaranteed to be 100% accurate. This learning modality dataset was generated by combining data from four different sources: Burbio [1], MCH Strategic Data [2], the AEI/Return to Learn Tracker [3], and state dashboards [4-20]. These data were combined using a Hidden Markov model which infers the sequence of learning modalities (In-Person, Hybrid, or Remote) for each district that is most likely to produce the modalities reported by these sources. This model was trained using data from the 2020-2021 school year. Metadata describing the location, number of schools and number of students in each district comes from NCES [21].
• You can read more about the model in the CDC MMWR: https://www.cdc.gov/mmwr/volumes/70/wr/mm7039e2.htm" target="_blank">COVID-19–Related School Closures and Learning Modality Changes — United States, August 1–September 17, 2021.
• The metrics listed for each school learning modality reflect totals by district and the number of enrolled students per district for which data are available. School districts represented here exclude private schools and include the following NCES subtypes:
  • Public school district that is NOT a component of a supervisory union
  • Public school district that is a component of a supervisory union
  • Independent charter district
• “BI” in the state column refers to school districts funded by the Bureau of Indian Education.

Technical Notes

• Data from September 1, 2020 to June 25, 2021 correspond to the 2020-2021 school year. During this timeframe, all four sources of data were available. Inferred modalities with a probability below 0.75 were deemed inconclusive and were omitted.
• Data for the month of July may show “In Person” status although most school districts are effectively closed during this time for summer break. Users may wish to exclude July data from use for this reason where applicable.

The purpose of this data collection was to provide a more accurate measure of the racial/ethnic enrollment in postsecondary institutions in the United States than was previously available. The National Center for Education Statistics (NCES) collects racial/ethnic enrollment data from higher education institutions on an annual basis. Some institutions do not report these data, and their "unknown" categories have previously been distributed in direct proportion to the "knowns." This resulted in lower than accurate figures for the racial/ethnic categories. With the advent of the Integrated Postsecondary Education Data System (IPEDS), NCES has attempted to eliminate this problem by distributing all "race/ethnicity unknown" students through a two-stage process. First, the differences between reported totals and racial/ethnic details were allocated on a gender and institutional basis by distributing the differences in direct proportion to reported distributions. The second-stage distribution was designed to eliminate the remaining instances of "race/ethnicity unknown." The procedure was to accumulate the reported racial/ethnic total enrollments by state, level, control, and gender, calculate the percentage distributions, and apply these percentages to the reported total enrollments of institutional respondents (in the same state, level, and control) that did not supply race/ethnicity detail. In addition, the original "race/ethnicity unknown" data were also left unaltered for those who wish to review the numbers actually distributed. The racial/ethnic status was broken down into nonresident alien, Black non-Hispanic, American Indian or Alaskan Native, Asian or Pacific Islander, Hispanic, and White non-Hispanic. There are six data files. Part 1, Institutional Characteristics, includes variables on control and level of institution, religious affiliation, highest level of offering, Carnegie classification, and state FIPS code and abbreviation. Variables in Part 2 cover total original enrollment by race/ethnicity and sex and by level and year of study of student. Race/ethnicity data were not imputed for institutions that only reported total enrollment. The "race ethnicity unknown" category was not distributed among the race/ethnicity categories. In Part 3, enrollment data are presented by race/ethnicity and sex of student, and by level and year of study for the following selected major field of studies: architecture, education, engineering, law, biological/life sciences, mathematics, physical sciences, dentistry, medicine, veterinary medicine, and business management and administrative services. This file contains data for four-year institutions only. Part 4 provides summary enrollment data by adjusted race/ethnicity and sex of student and by level and year of study of student. The "race/ethnicity unknown" category data were distributed across all known race categories in this file. Also, race data were imputed for institutions that did not report enrollment by race. Part 5, Residence and Migration, contains enrollment data for first-time freshmen, by state of residence. Part 6, Clarifying Questions on Enrollments, provides information on students enrolled in remedial courses, extension divisions, and branches of schools, and numbers of transfer students from in-state, out of state, and other countries.

The Integrated Postsecondary Education Data System, 2006-07 (IPEDS 2006-07), was a study that was part of the Integrated Postsecondary Education Data System (IPEDS) program; program data is available since 1980 at . IPEDS 2006-07 (https://nces.ed.gov/ipeds/) was a cross-sectional survey designed to collect basic data from all postsecondary institutions in the United States and the other jurisdictions. Key statistics produced from IPEDS 2006-07 allowed the National Center for Education Statistics (NCES) to describe the size of one of the nation's largest enterprises--postsecondary education-- in terms of students enrolled, degrees and other awards earned, dollars expended, and staff employed. All Title IV institutions were required to respond to IPEDS (see Section 490 of the Higher Education Amendments of 1992 [P.L. 102-325; 20 U.S.C. � 1070 et seq.]). IPEDS allowed other, non-Title IV institutions to participate on a voluntary basis, but only about 200 elected to respond.

This dataset contains records for each public elementary and secondary school in the 50 states, the District of Columbia, and outlying areas (American Samoa, Guam, Puerto Rico, the Virgin Islands, and the Marshall Islands) in fall 1979. The project permits the educational community to draw statistically valid samples from which state or national estimates can be made and also provides a mailing list of school systems. Significant variables include name, address, county, grade span, size of system, number of schools, and Standard Metropolitan Statistical Area (SMSA) designation.

The National Center for Education Statistics’ (NCES) Education Demographic and Geographic Estimate (EDGE) program develops annually updated school district boundary composite files that include public elementary, secondary, and unified school district boundaries clipped to the U.S. shoreline. School districts are single-purpose administrative units designed by state and local officials to organize and provide public education for local residents. District boundaries are collected for NCES by the U.S. Census Bureau to support educational research and program administration, and the boundaries are essential for constructing district-level estimates of the number of children in poverty. The Census Bureau’s School District Boundary Review program (SDBR) (https://www.census.gov/programs-surveys/sdrp.html) obtains the boundaries, names, and grade ranges from state officials, and integrates these updates into Census TIGER. Census TIGER boundaries include legal maritime buffers for coastal areas by default, but the NCES composite file removes these buffers to facilitate broader use and cleaner cartographic representation. The NCES EDGE program collaborates with the U.S. Census Bureau’s Education Demographic, Geographic, and Economic Statistics (EDGE) Branch to develop the composite school district files. The inputs for this data layer were developed from Census TIGER/Line 2019 and represent boundaries reported for the 2018-2019 school year. For more information about NCES school district boundary data, see https://nces.ed.gov/programs/edge/Geographic/DistrictBoundaries. All information contained in this file is in the public _domain. Data users are advised to review NCES program documentation and feature class metadata to understand the limitations and appropriate use of the data.
