An Open Badge is a digital image file — typically a PNG or SVG — that carries signed, verifiable metadata about an achievement baked directly into it according to a specification maintained by 1EdTech (formerly IMS Global). The current version, Open Badges 3.0, aligns with the W3C Verifiable Credentials Data Model, meaning a badge can now be stored in a digital wallet and cryptographically verified by any third party without contacting the issuing institution. Each badge contains the criteria for earning it, the issuer's identity, the recipient's identity, and an evidence URL, making it self-contained and independently verifiable. Learners can share badges on LinkedIn, portfolios, and email signatures; employers and hiring platforms can verify authenticity by checking the embedded signature rather than relying on a PDF that could be forged. Open Badges differ from simple completion certificates in that they encode structured, machine-readable achievement data rather than just a flat document. Practical implementation requires choosing a badge platform or building issuance into an LMS, defining clear criteria aligned to learning outcomes, and deciding on revocation handling should a badge need to be invalidated. Open Badges are most valuable when the credential names a discrete, verifiable skill rather than broad course attendance.
