終身學習
Lifelong learning has been described as a process that includes people learning in different contexts. These environments do not only include schools but also homes, workplaces, and even locations where people pursue leisure activities. However, while the learning process can be applied to learners of all ages, there is a focus on adults who are returning to organized learning. There are programs based on its framework that address the different needs of learners, such as United Nations' Sustainable Development Goal 4 and the UNESCO's Institute for Lifelong Learning, which caters to the needs of the disadvantaged and marginalized learners.
