Data are reported at state, district, and school levels and include staff counts by professional category, as well as student membership disaggregated by grade, race/ethnicity, and sex. Also included are school-level counts of students eligible for free and reduced-price lunch. Along with the data files, four web tables summarizing select CCD data elements including the number and status of schools and local education agencies, as well as several CCD indicators by state, are also available.

NCES 2022047 Trends in International Mathematics and Science Study (TIMSS) 2019 U.S. public-use data files and documentation

The TIMSS 2019 U.S. public-use data files and documentation include the following at grades 4 and 8: student, teacher, and school data in ASCII text format; SPSS and SAS control files for reading the ASCII data to produce SPSS and SAS data files; codebooks; illustrative merging code; a Read Me file; and a Quick Guide. Also included for each of the grades are the analogous files for the Bridge study, which was conducted to form a link between eTIMSS countries’ computer-based data in 2019 and their paper-based data in 2015 as well as to the paper-based TIMSS countries in 2019. Additionally, analogous eTIMSS with PSI files include the data files for eTIMSS that contain additional data for the students that were administered problem-solving inquiry tasks (PSIs).

The TIMSS 2019 U.S. public-use student, teacher, and school data files include U.S. specific variables that are not part of the U.S. data files in the IEA’s TIMSS 2019 international database. They are add-on files that do not contain weight variables or replicate weights, and therefore must be merged with the U.S. data files in the IEA’s public-use international database before any analysis can be conducted. The U.S. data files in the IEA’s public-use international database can be downloaded at https://timss2019.org/international-database/. Users of this data should consult the U.S. Technical Report and User Guide for the 2019 Trends in International Mathematics and Science Study (TIMSS) available for viewing and downloading at https://nces.ed.gov/pubsearch/pubsinfo.asp?pubid=2022049.

NCES 2022048 Trends in International Mathematics and Science Study (TIMSS) 2019 U.S. restricted-use data files and documentation
The TIMSS 2019 U.S. restricted-use data files and documentation include the following at grades 4 and 8: student and school data in ASCII text format; SPSS and SAS control files for reading the ASCII data to produce SPSS and SAS data files; codebooks; illustrative merging code; a Read Me file; and a Quick Guide. Also included for each of the grades are the analogous files for the Bridge study, which was conducted to form a link between eTIMSS countries’ computer-based data in 2019 and their paper-based data in 2015 as well as to the paper-based TIMSS countries in 2019. The TIMSS 2019 U.S. restricted-use student and school data files include U.S. specific variables that are not part of the TIMSS 2019 U.S. public-use data files or the U.S. data files in the IEA’s TIMSS 2019 public-use international database. They include NCES school IDs that facilitate merging with the Common Core of Data (CCD) for public schools and the Private School Universe Survey (PSS) for private schools. They are add-on files that do not contain weight variables or replicate weights, and therefore must be merged with the U.S. student and school data files in the IEA’s public-use international database before any analysis can be conducted. The U.S. data files in the IEA’s public-use international database can be downloaded at https://timss2019.org/international-database/. Users of this data should consult the U.S. Technical Report and User Guide for the 2019 Trends in International Mathematics and Science Study (TIMSS) available for viewing and downloading at https://nces.ed.gov/pubsearch/pubsinfo.asp?pubid=2022049.

NCES 2022084 The 2018 National Assessment of Educational Progress (NAEP) Grade 4 Oral Reading Fluency Study Public-Use Data File
The 2018 NAEP Oral Reading Fluency (ORF) study was conducted by NCES to examine public-school fourth-grade students’ ability to read passages out loud with sufficient speed, accuracy, and expression, as well as foundational skills, to gauge underlying sources of poor fluency. The public-use data file contains oral reading performance variables, student contextual information, NAEP reading scores and achievement-level and below NAEP Basic subgroup variables, and student sample weights and replicate weights. The data companion provides background on the 2018 NAEP Oral Reading Fluency (ORF) study and a description of oral reading fluency and the study design. It also describes the 2018 NAEP ORF study instrument development and provides the sampling design and response rates, variables included in the data file, information needed to conduct statistical analyses using the 2018 NAEP ORF data, and control statement files to create system files in SAS and Stata.

NCES 2023004 Program for the International Assessment of Adult Competencies (PIAAC) County-level Estimation for Age and Education Groups Methodology Report
This is the third methodology report on Program for the International Assessment of Adult Competencies (PIAAC) Small Area Estimation (SAE) published by the National Center for Education Statistics in PIAAC Cycle I. The first report was written to describe the methodology used for the purpose of creating model-based estimates of average scores and high, middle, and low proficiency levels of adult skills for all states and counties in the U.S. The second report described the statistical models to produce the same types of estimates for state-level age and education groups. This report describes the methodology used to produce the county-level estimates by age and education groups.

NCES 2022122REV 2021-22 Common Core of Data (CCD) Preliminary Files

These files are the product of the CCD data collection for the 2021-22 school year. Data are reported at state, district, and school levels as of October 1, 2021.

This CCD release includes preliminary Directory (version 0b), CCD School (version 0a), and Student Membership (version 0a) data. The version 0b preliminary Directory data in this release reflect updates made after the February 28, 2022 submission deadline and replace the 0a version Directory data released on May 11, 2022. The CCD School and Student Membership data in this release largely represent the data submitted by the state education agencies as of the April 29, 2022 file submission due date and include detailed data (i.e., student counts by grade, race/ethnicity, and sex) at the SEA level and total membership minus adult education at the district and school levels. Washington was not able to submit Student Membership data as of the submission deadline.

While the preliminary files have been reviewed to verify that the counts are within expected ranges, the data in this release has not yet undergone the full data quality review process and may contain errors that have not yet been resolved. They are meant to provide data users with a timely data release. Due to the preliminary nature of the data, users should analyze the data with caution.
