What the page proves.
The finding
Virtual-school flags identify remote or primarily online public schools.
How to read it
Use flags with enrollment, district, and state context. A virtual flag describes delivery model, not program quality.
Source and vintage
NCES CCD SY 2023-24 with CRDC 2021-22 fallback where needed. K12 Atlas release v2026.07.
Use and limits
This page does not infer why enrollment changed and does not label schools.
CSV is a public summary slice, not the full paid sheet.
How to cite and connect this page.
Citation pattern
Cite the metric as K12 Atlas, release v2026.07, with the named source and vintage shown on this page. Do not cite it as a live real-time measurement.
Internal-link role
This page is the source-backed node for related explainers, glossary definitions, state hubs, and the sample report. It should receive links from at least two pages and link outward to at least four.
CSV role
The CSV is intentionally a summary slice. It proves the field shape and source logic while keeping the full paid sheet separate.
Review rule
Before each release refresh, rerun the mart query, update the number, and keep the old framing only if the source and vintage still match.
