Lifelong learning or LLL ( permanent training or permanent learning or continuous learning) is an intentional individual process that aims at the acquisition of roles and skills and which involves a relatively stable change over time. This process has the objective of modifying or replacing learning that is no longer adequate concerning new social or work needs, in the professional or personal field.

The term "lifelong learning" means education throughout life, from birth to death, that education that begins even before school and continues until after retirement.
