Competency-based learning or Competency-Based Education and Training is an approach to teaching and learning more often used in learning concrete skills than abstract learning. It differs from other non-related approaches in that the unit of learning is extremely fine grained.
Competency-Based Progression. Each studentâs progress toward clearly-defined goals is continually assessed. A student advances and earns credit as soon as he/she demonstrates mastery. Flexible Learning Environments. Student needs drive the design of the learning environment. All operational elementsâstaffing plans, space utilization and time allocationârespond and adapt to support students in achieving their goals.
