Informal learning occurs through everyday activities outside of formal education and training and does not lead to qualifications. It is continuous, unstructured, spontaneous, intrinsic, voluntary, learner-led, and not evaluated. Informal learning benefits disengaged learners, older workers who can utilize life experience, workers and businesses who can focus on organizational needs, and migrants who can build language and community skills. It occurs through reading, technology use, media consumption, volunteering, learning from others, on-the-job training, and trial and error. Communities of practice are groups that share purpose and knowledge through mutual engagement and negotiated agreements.
