California Public Schools 2025-26

This layer serves as the authoritative geographic data source for California's TK/K-12 public school locations for the 2025-26 academic year. Schools are mapped as point locations and assigned coordinates based on the physical address of the school facility. The school records are enriched with additional demographic and performance variables from the California Department of Education's data collections. These data elements can be visualized and examined geographically to uncover patterns, solve problems and inform education policy decisions. The schools in this file represent a subset of all records contained in the CDE's public school directory database. This subset is restricted to TK-12 public schools that were open in October 2025 to coincide with the official 2025-26 student enrollment counts collected on Fall Census Day in 2025 (first Wednesday in October). This layer excludes nonpublic schools and district office schools, so the total public school enrollment in this file will differ from the CDE's official statewide Fall 1 Census Day total enrollment. CDE's official Fall 1 2025-26 public school enrollment (5,731,260) - nonpublic school enrollment (8,645) - district office school enrollment ( 5,917) = 5,716,698. The CDE's California School Directory provides school location other basic school characteristics found in the layer's attribute table. The school enrollment, demographic and program data are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as publicly downloadable files from the Data & Statistics web page on the CDE website. Schools are assigned X, Y coordinates using a quality controlled geocoding and validation process to optimize positional accuracy. Most schools are mapped to the school structure or centroid of the school property parcel and are individually verified using aerial imagery or assessor's parcels databases. Schools are assigned various geographic area values based on their mapped locations including California County Superintendents Educational Services (CCSESA) district numbers, state and federal legislative district identifiers and National Center for Education Statistics (NCES) locale codes.

本地理数据图层为2025-26学年加州TK/K-12公立学校位置的权威地理数据源。本数据集将学校以点位形式映射，并依据学校实体设施的物理地址分配坐标。学校记录附加了来自加州教育部（California Department of Education, CDE）数据收集中的人口统计与绩效相关变量，以丰富数据维度。可对这些数据要素开展地理可视化与分析，以挖掘潜在规律、解决实际问题，并为教育政策制定提供决策依据。

本文件收录的学校为加州教育部公立学校名录数据库中全部记录的一个子集。该子集仅包含2025年10月处于运营状态的TK/K-12公立学校，以匹配2025年秋季普查日（10月第一个周三）采集的2025-26学年官方学生在校人数统计结果。本图层不包含非公立学校与学区办事处学校，因此本文件中的公立学校总在校人数将与加州教育部公布的全州秋季1日普查日官方总在校人数存在差异。加州教育部公布的2025-26学年秋季1日公立学校官方在校人数（5,731,260）减去非公立学校在校人数（8,645），再减去学区办事处学校在校人数（5,917），最终结果为5,716,698。

加州教育部的《加州学校名录》提供了本图层属性表中收录的学校位置及其他基础学校特征信息。学校在校人数、人口统计与项目数据由加州教育部通过加州纵向成就系统（California Longitudinal Achievement System, CALPADS）采集，用户可从加州教育部官网的数据与统计页面下载获取这些公开文件。

学校的X、Y坐标通过经过质量管控的地理编码与验证流程分配，以最大化点位定位精度。多数学校点位映射至学校建筑或学校地块的质心，并通过航空影像或评估员地块数据库进行逐一验证。系统会根据学校的映射位置为其分配各类地理区域属性值，包括加州县教育总监教育服务区（California County Superintendents Educational Services, CCSESA）学区编号、州与联邦立法选区标识，以及美国国家教育统计中心（National Center for Education Statistics, NCES）的区域代码。
