Then reconsider whether this is the position you really want to work toward. If you don't have these qualities, find opportunities to learn them. Leadership is essential at all levels of administration, although it may take different forms. At lower levels, it may be the ability to organize and carry out a complex project, involving and motivating others, and getting the work done well and on time. At higher levels, it is more likely to be the ability to conceptualize what needs to be done, to articulate it persuasively, and to shape a process of deliberation that includes all the necessary constituencies.
Communication is another essential capability at all levels.
Do more than assert your abilities. You must demonstrate them with examples, and you need references who can vouch for you, preferably someone who has observed your work firsthand on a regular basis. Some people have certainly done this, but it's rare. Those who make big leaps tend to have a record of exceptional accomplishment, recognized not only within their own institution but also beyond it. Many years of experience in the previous position may enable such a leap.
