The process of removing or revoking an official certification, license, or credential from a person or organization.
From de- (reversing an action) + certification. Certification comes from Late Latin certificare (to assure), so decertification means to undo that assurance officially.
Decertification became super common in modern labor law—when workers vote to remove a union's right to represent them, that's decertification, and it shows how 'de-' words let us express reversal of modern institutions.
