Self-awareness is essential to leader development. Internal self-awareness refers to how well we see and understand ourselves and our impact on others. External self-awareness refers to the extent to which we understand how others see us. To optimize self-awareness, it is important to receive and provide frank and meaningful feedback.

The creation of a self-assessment and peer feedback tool would help provide individuals with clear assessments of their leadership knowledge and skills as well as perspectives from peers with whom they work closely.

This tool can be used within leader development programs to enhance selfawareness and peer perceptions to further develop leaders.
