Metacognition, or having an awareness of one's thought processes, is an integral part of learning. Fostering metacognitive abilities enhances self-awareness and the ability of learners to engage with complexity. Metacognition underscores all aspects of leadership learning, including knowledge, development, training, observation, and engagement. Educators develop metacognitive abilities through explicitly teaching metacognitive skills, scaffolding learning, and engaging critical perspectives. As leadership educators develop metacognitive abilities and incorporate learning about metacognition in curricular and co-curricular settings, the field of leadership education amplifies opportunities for learners to facilitate positive and sustainable change.
