The National Association of Independent School ("NAIS") has done a lot of thinking about Headship, and how to categorize and measure the different skills that comprise the job.
They put it this way: “Our competency modeling identifies 14 domains that are highly relevant for headship:
- Adaptability
- Mentoring and coaching
- Financial acumen
- Decision making
- Diversity
- School mission and values
- Leadership
- Social awareness
- Managerial effectiveness
- Personal effectiveness
- Teamwork
- Communication
- Vision
- Emotional intelligence
I think the list represents a good start.
