This documentation is for the Provisional File Version 1a of the School-Level Finance Survey (SLFS) for school year (SY) 2021-22, fiscal year 2022 (FY 22) conducted by the National Center for Education Statistics (NCES). It contains a brief description of the data collection in conjunction with information required to understand and access the data file. The School-Level Finance Survey consists of data submitted annually to NCES by state education agencies (SEAs) and is the only national, centrally-collected data collection of public elementary and secondary school-level finances in the United States. The survey provides finance data for schools that provide free public elementary and secondary (prekindergarten through grade 12) education in the United States. The FY 22 SLFS data file contains 106,961 records representing public elementary and secondary education schools across the 50 states and the District of Columbia. SEAs reported finance data for 100,736, or 94.2 percent, of those school records. The data file includes variables for current expenditures, salaries, and employee benefits by function; selected exhibit and other expenditure items of interest (e.g., teacher salaries, books and periodicals, selected technology expenditures); as well as identification and school characterization variables for each school. This document includes a user's guide, which contains information on the methodology of this survey, and five appendices: (1) Record Layout and Descriptions of Data Items; (2) Glossary; (3) State Notes; (4) Summary Tables; and (5) Survey Form.
