Certificate verification

This certificate has been withdrawn

Certificate B7A8B561-7678 was genuinely issued by Ockem Proof on Oct 12, 2026. Withdrawn on Oct 19, 2026. Ockem no longer stands behind this certificate.

Why you are seeing this

Ockem withdrew this certificate: in the document version it describes, text that a screen reader speaks in place of the printed words was wrong — reversed, spelled out letter by letter, or cut off at a page break — because Ockem's automated remediation wrote it, so the result it reports did not hold for people using assistive technology. The certificate was genuinely issued; its verdict should not be relied on. Treat any copy of this certificate as historical: it records a real assessment made on Oct 12, 2026, but it is not a current claim of conformance.

This certificate was genuinely issued by Ockem Proof and has since been withdrawn. The verdict recorded at issuance is shown below; it is no longer a current claim.

Verified by Ockem Proof

35 automated checks ran against this exact file version and detected no violations. This is the only part of the certificate Ockem Proof asserts from its own testing.

Attested by The City of Alderbrook

3 criteria that automated testing could not determine were confirmed by The City of Alderbrook’s attester of record, whose identity is on file under this Certificate ID. For logical reading order, a person confirmed the order on pages 1, 2, 4, 5, 6, 7, 9, 11, 14, 16, 17, 18, 19 and 20 of 21 only; automated testing, not a person, verified the order of the other 7 pages. Ockem Proof relied on these attestations and did not independently review them. The certificate was issued automatically on meeting all criteria.

Not claimed

This certificate is not a legal determination of compliance with the ADA, Section 508, Section 504 or any other law, and is not a warranty that no accessibility barrier exists. It applies only to the file version it names; editing or re-exporting the file voids it.
