Micro-credentials are transforming digital education by offering flexible, targeted, and accessible ways for learners to acquire and demonstrate skills. Micro-Credentials are small, specialized certifications following a short learning experience, which recognize the knowledge or skills someone acquires in specific subjects or fields. Since 2011, when the Mozilla Foundation introduced the Open Badges system, the use of Micro-Credentials has grown and is now widely employed by all digital platforms offering distance education (Coursera, edX, Udacity, etc.) to certify learners' knowledge, and they are recognized as additional qualifications by employers. Micro-Credentials are becoming increasingly popular as an alternative or complementary form of education, particularly in fields where skills evolve rapidly, such as technology and digital skills, and represent a significant advancement in the field of non-formal and lifelong learning.
