Definition
A feeder pattern is the structured path that students in a school district typically follow as they graduate from one level of schooling to the next (e.g., from elementary school to middle school, and middle school to high school). It represents the physical or administrative flow of cohorts through the local school system.
How K12 Atlas uses it
K12 Atlas constructs a feeder pattern network using NCES School Attendance Boundary Survey (SABS) geographic intersections and school directory spans. This database links elementary and middle schools to their downstream high schools, mapping 1.32 million relationship rows.
Source caveats
Feeder patterns are dynamic and subject to change due to district rezoning, school closures, or grade-reconfiguration plans. Additionally, many districts utilize open enrollment, magnet programs, charter schools, or specialized academies that bypass traditional feeder paths, making physical boundaries only one part of the story.
Implementation rule
To maintain accuracy, the K12 Atlas graph distinguishes between 'exact' geographic boundary alignment (derived from SABS maps) and 'district-level fallback' relationships (where a smaller school is linked to a downstream school in the same district based on geographic proximity or directory overlaps).
Organic role
This entry explains student educational pathways. It links to the feeder patterns data story, explainers on how to read feeder relationships, and the sample reports.
What not to infer
A feeder relationship is a structural probability, not an absolute guarantee of attendance. Parents should check official district enrollment guidelines rather than relying on boundary overlaps for housing decisions. K12 Atlas provides these links purely as relational data.
