What this gap means
robots.txt disallows both ChatGPT-User and Claude-User for the whole site, so neither assistant will open its pages for a user who asks.
Control: robots.txt verdicts for ChatGPT-User and Claude-User. Rule: blocks_assistants over the census record (reachable sites only). Who buys this: AI-visibility vendors and digital agencies: these sites are closed to ChatGPT and Claude users.
This list maps to no legal obligation in this census; it is a gap in published practice.
By state
36 states with at least one school district on this list; "of the state" is the share of its school districts in the census list. One state as CSV: 0.25 USDC (x402).

Atom feed: school districts that entered or left this list according to the live re-checks (every 6 hours a rotating slice, each domain at most once per 14 days; each entry says which way it moved and which field changed). blocks-assistants.top.json: the first 50 rows and the counts by state as JSON, CORS open.

Membership reflects the homepage and well-known files as fetched on 2026-09-30: a control that exists but was not found where the census looked counts as missing, and sites answering 403 to our one polite request count as reachable.
