What school districts are expected to publish
- ADA Title II web rule (WCAG 2.1 Level AA): Public school districts are state and local government entities and must make their web content and mobile apps conform to WCAG 2.1 Level AA: entities serving 50,000 or more people from April 24, 2026, smaller entities from April 26, 2027 (28 CFR Part 35, subpart H). The census checks only whether the homepage links an accessibility statement. Source
- Section 504 of the Rehabilitation Act (34 CFR Part 104): Recipients of federal education funds may not exclude people with disabilities from their programs and activities, which the Department of Education applies to websites and online services. Source
- FERPA annual notification (34 CFR 99.7): Districts must notify parents and eligible students each year of their rights under the Family Educational Rights and Privacy Act; many post the notice on the district website. The census checks only for a privacy link on the homepage. Source
- ESSA report cards (ESEA section 1111(h)): Each local education agency receiving Title I funds must prepare an annual report card and make it widely accessible to the public, including on its website (Every Student Succeeds Act, Public Law 114-95). Source
- Children's Internet Protection Act (47 U.S.C. 254(h)): Schools receiving E-rate discounts must adopt and enforce an internet safety policy with a technology protection measure and give public notice of it. Source
- RFC 9116 security.txt: The security.txt standard defines the /.well-known/security.txt location and requires Contact and Expires fields so researchers can report vulnerabilities; the census marks a file complete when both are present and unexpired. Source

Questions
Why do so many school districts publish a security.txt?
4,003 of the 14,653 reachable district sites (27.3%) serve a security.txt, but a spot check of ten of them found every file supplied by the district's website vendor (Apptegy, Contact: security@apptegy.com), not written by the district. Read the figure as vendor coverage of vulnerability disclosure, not district practice.
How many school district websites publish a security.txt?
4,003 of the 14,653 reachable district websites (27.3%) publish a security.txt; 3,889 are complete and current.
Do school district websites link an accessibility statement?
21.1% of reachable district homepages link an accessibility statement and 11.4% link a privacy policy. The ADA Title II web rule reaches districts serving 50,000 or more people on April 24, 2026 and smaller districts on April 26, 2027.
How many districts block AI crawlers?
555 district websites block GPTBot, 546 block ClaudeBot and 538 block ChatGPT-User in robots.txt; 279 disallow every bot; 566 publish an llms.txt.

Method and limits
Population: NCES Common Core of Data, Local Education Agency Universe Survey directory 2024-25 (agencies with a website address) with each agency's type, city, state and number of operational schools as published for 2024-25. Many district sites run on a handful of website vendors; vendor-supplied files such as security.txt are counted as published, and the FAQ says so.. Fetch: one HTTPS request to the apex (then www.), following redirects, 8-second timeout, user agent agentexchange-census/1.0; then robots.txt, /.well-known/security.txt, /security.txt, /llms.txt and /.well-known/agent-card.json on the final host. "Reachable" means any HTTP response over HTTPS, including 403s from bot protection. Homepage links are detected from anchor targets and visible text, so a policy that exists but is not linked from the homepage is not counted. A robots.txt "blocked" verdict means the agent's own group (or the * group) disallows the whole site; "partly blocked" means some paths are disallowed. One snapshot per domain; slow sites and sites that block automated requests are counted as unreachable or reachable-with-error as the server answered. Per-domain records: lookup; downloads: CSV, NDJSON and JSON (CC BY 4.0).
