What an open badge is
A digital badge is a small image that represents something a person has learned or done: finishing a short course, demonstrating a skill, contributing to a project. An open badge goes a step further. It is built to a published, shared specification, so the badge is more than a picture. It carries structured information, and it can be stored, shown and checked outside the system that issued it.
The specification was first developed in the early 2010s, and has been revised since. It is now maintained by a standards body rather than by a single company. Because the format is public, many different organizations can issue badges, and many different tools can display them.
What a badge actually contains
The picture is the least important part. Embedded in the file, or linked from it, is information that typically includes:
- The recipient, identified in a way that can be matched to the person, often an email address in hashed form.
- The issuer, meaning the organization or person who awarded it.
- The criteria, a description of what had to be done to earn it.
- The date of issue, and sometimes an expiry date.
- Evidence, such as a link to the work the person submitted.
This is what makes a badge a record rather than a sticker. A reader who clicks through can see who vouches for it, what was required and what the holder produced. A badge with vague criteria and no evidence tells the reader very little.
Portability and verification
The main promise of open badges is portability. A learner can collect badges from several places into one backpack-style collection and share selected ones on a personal website, a professional profile or an application. They are not tied to one course website that may close.
Verification works in two common ways. In a hosted approach, the badge data sits on the issuer’s web address, and a checker follows the link to confirm it. In a signed approach, the badge is digitally signed so that changes can be detected. Either way, verification confirms that the issuer did award the badge. It does not on its own confirm that the learning behind it was rigorous.
Newer versions of the specification have moved closer to general verifiable credential standards, so that badges and other digital records can use similar methods. Readers who want details should check the current published specification, as it changes over time.
How badges can support learning
Badges are used in several ways, and the research on their effects is mixed.
- Recognizing small steps. A short sequence of badges can show progress in a long program, which some learners find motivating. Others find the effect small or short-lived.
- Capturing informal learning. Skills picked up through volunteering, open courses or self-study seldom appear on a transcript. Badges give them a shareable form.
- Describing skills in finer detail. A degree title is broad; a set of badges can list particular abilities. This links to the wider conversation about micro-credentials, which are short, focused qualifications.
- Supporting teachers and trainers. Educators can use badges to recognize professional development they have completed.
A badge system also fits neatly beside lifelong learning, since people can add to their record over many years and from many providers.
Limits and cautions
Badges are only as meaningful as the people behind them. Three issues come up repeatedly.
Credibility varies. Anyone can create a badge, so a reader must judge the issuer. A badge from a respected organization with clear criteria carries more weight than one from an unknown source with none.
Recognition is uneven. Employers, universities and funders differ in whether they pay attention to badges at all. A learner should not assume a badge will count for admission, pay or hiring. That depends on the receiving organization.
Over-awarding. If badges are handed out for trivial activity, they stop distinguishing anyone. Good schemes tie each badge to a defined task or assessment.
There is also a privacy side. Badges can reveal where and when a person studied, so learners should decide what to share publicly. Our notes on personal data sharing and privacy settings apply here as well.
Designing a sensible badge scheme
For a teacher or organization thinking about issuing badges, a few principles tend to help:
- Define clear criteria that someone outside the course could understand.
- Attach evidence where possible, so the badge is about observed work.
- Keep the number of badges modest and each one meaningful.
- Use the shared specification rather than a private format, so that learners can take badges elsewhere.
- Explain to learners who they can show badges to, and be honest about what recognition they can expect.
Where badges sit in open education
Open badges follow the same logic as open content and open software: a public format that lets different systems work together. They address a different gap, which is recording and recognizing what people have learned. Used with care and clear criteria, they can make learning more visible. Used carelessly, they become decoration. Their usefulness depends on the quality of the learning behind them and on whether others choose to trust them.
