Editorial translation; the original Portuguese version prevails in case of discrepancy.
Standards we follow
This site's structure was designed from public standards of journalistic transparency. They define what an outlet needs to publish about itself to be held accountable. Below, each standard, a link to the original text and what we did because of it.
Notice on non-certification
Following a standard is not the same as being certified by it. Revalida is not certified, evaluated or audited by any of the entities named on this page, and will not be on launch day. We adopted the structure these standards require precisely so that an audit is possible whenever it makes sense to request one. Any text suggesting a seal, partnership or approval from these organizations would be wrong, and we ask that you let us know.
The Trust Project — 8 Trust Indicators
thetrustproject.org/trust-indicators
Eight indicators an outlet makes public: best practices (standards, ownership, funding, corrections), the expertise of whoever signs the piece, type of content, citations and references, methods, local sources, diversity of voices and an actionable feedback channel.
What we did: pages on principles, ownership and funding, corrections and contact; and, in every piece, the "How we verified it and how it was reviewed", "Sources" and "Right of reply" blocks.
Journalism Trust Initiative — CEN CWA 17493 standard
A European technical standard created from a Reporters Without Borders initiative: identity, transparency, accountability, professionalism, independence and ethics, with certification by an external auditor.
What we did: the site is born with the documentation the standard requires — who we are, who pays, how we investigate, how we correct and how to complain.
IFCN — Code of Principles
ifcncodeofprinciples.poynter.org
Five commitments from fact-checkers: nonpartisanship, transparency of sources, of funding and organization, transparency of methodology, and an open corrections policy.
What we did: the same criterion for any subject; primary sources cited with excerpt and link; funding disclosed; methodology public; corrections at the top of the piece.
ClaimReview (schema.org)
Google's documentation · schema.org/ClaimReview
Structured markup that lets search engines and aggregators recognize a check: which claim was assessed, by whom, with what result.
What we did: every revalidation publishes NewsArticle and a ClaimReview with the claim assessed and the label.
WCAG 2.2, level AA
Accessibility guidelines for web content: contrast, keyboard navigation, visible focus, semantics, alternative text, target size.
What we did: light and dark themes with checked contrast, a skip-to-content link, visible focus, tables that become readable cards on mobile, images with descriptions and no information conveyed by color alone.
