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.</font></span></p><p style='margin-top:0px; margin-bottom:8px; margin-left:4px; padding-bottom:1em; font-family:&quot;Segoe UI&quot;, Arial, sans-serif;'><span style='background-color:rgb(255, 255, 255);'><font size='3'>The schools in this file represent a subset of all records contained in the CDE's public school directory database.

Schools are assigned various geographic area values based on their mapped locations including state and federal legislative district identifiers and National Center for Education Statistics (NCES) locale codes.</font></span></p>

本图层为2023-2024学年加州K-12公立学校校址提供权威地理数据源。所有学校以点要素形式映射，并基于校址实体地址赋予坐标。学校记录补充了来自加州教育部（California Department of Education, CDE）数据采集项目的人口统计与绩效相关变量。可通过地理可视化与空间分析对这些数据要素进行探究，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支撑。

本文件收录的学校为CDE公立学校名录数据库中全部记录的子集。该子集限定为2023年10月处于运营状态的K-12公立学校，以匹配2023年秋季普查日（10月第一个周三）采集的2023-2024学年官方学生在册人数统计结果。本图层同时排除非公立非教派学校与学区办事处学校。

CDE的《加州学校名录》提供了本图层属性表中收录的学校校址及其他基础办学特征信息。学校在册人数、人口统计与项目相关数据由CDE通过加州纵向学业成就系统（California Longitudinal Achievement System, CALPADS）采集，用户可从CDE官网的「数据与统计」页面下载获取这些公开文件。

本图层通过经质量管控的地理编码与验证流程为学校赋予X、Y坐标，以优化位置精度。多数学校的映射点位对应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逐一核验。根据映射后的点位，学校被赋予各类地理区域属性值，包括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）区位代码。
