This paper reports a study on the leadership capacities of a group of 185 aspiring principals. A questionnaire consisting of 24 questions was constructed to examine the levels of leadership capacities of these aspirants. The findings indicate that the aspirants seemed to feel more competent in the leadership area of 'teacher professional growth and development' than they did with regard to 'quality assurance and accountability', 'learning, teaching and curriculum', 'strategic direction and policy environment', 'external communication and connection to the outside world', and finally 'staff and resources management'.[Copyright © Elsevier Ltd].
