Iowa School Districts 2024-2025

This dataset is a representation of legal school district boundaries in Iowa for the 2024-2025 school year. The Iowa Department of Education conducts a biennial statewide review of school district boundaries in conjunction with the U.S. Census Bureau School District Review Program (SDRP) to record district reorganizations, to verify legal boundaries and improve the accuracy of boundary alignment. This dataset is a representation of the boundaries as they exist upon the close of the SDRP on January 31, 2024. Legal school district boundary information was requested from each school district and county auditor in the form of shapefiles and/or written descriptions. Priority of data used to edit boundaries is as follows: 1. Written descriptions of the school district boundary (the authoritative source). 2. Official map or shapefile representing the written legal description. 3. If no legal description is available or if the description was determined to be incomplete or out-of-date, then county tax parcel data was used, in conjunction with Public Land Survey System (PLSS) Township/Sections. Where information could not be obtained locally, tax district data provided by the Iowa Department of Revenue was considered and edits applied where it was evident accuracy improvements could be made.

本数据集为2024-2025学年爱荷华州法定学区边界的数字化呈现。爱荷华州教育部与美国人口普查局学区审查项目（School District Review Program, SDRP）联合开展每两年一次的全州学区边界审查工作，旨在记录学区重组情况、核实法定边界并提升边界对齐精度。本数据集呈现的是2024年1月31日SDRP审查结束时的有效学区边界。法定学区边界信息通过形状文件（shapefile）与书面说明两种形式，向全州各学区及县审计员征集。用于编辑边界的数据源优先级依次为：1. 学区边界的书面说明（权威来源）；2. 匹配该法定书面说明的官方地图或形状文件（shapefile）；3. 若无合法边界说明，或说明被认定为不完整、过时，则采用县税收宗地数据，并结合公共土地测量系统（Public Land Survey System, PLSS）的乡/区块进行校准。若无法通过本地渠道获取相关信息，则参考爱荷华州税务局提供的税收辖区数据，并在确认可提升精度的前提下进行边界修正。
