Digital badges are validated indicators of skills or competencies, often representing the completion of a microcredential. Badges typically represent competencies not shown on a transcript, including learning from internships, volunteer work, and other co-curricular activities. Increasingly, badges conform to the Open Badges standard, and many are stackable, meaning that they can be credited toward an advanced badge, a certificate, or a degree.
