There are two criteria of servant leadership:

• The people served grow as individuals, becoming ‘healthier, wiser, more autonomous and more likely themselves to become servants’ (Greenleaf, 1977).
• The extent to which the leadership benefits those who are least advantaged in society (or at least does not disadvantage them).

Principles of servant leadership defined by the Alliance for Servant Leadership are:

• Transformation as a vehicle for personal and institutional growth.
• Personal growth as a route to better serve others.
• Enabling environmentsthat empower and encourage service.
• Service as a fundamental goals.
• Trusting relationshipsas a basic platform for collaboration and service.
• Creating commitmentas a way to collaborative activity.
• Community building as a way to create environments in which people can trust each other and work together.
• Nurturing the spiritas a way to provide joy and fulfilment in meaningful work
