Leadership qualities are important to be a competitive applicant in the health field. Students who have taken initiative, planned a program or activity, and demonstrated commitment make a strong postive impact to selection committees. Students who have just held high ranking titles such as president, director, or chair in an organization but have little to show for it do not impress school selection committees. It is more valuable to have no title but be able to show initiative and ability to take an idea to fruition.
Instead of seeking positions and titles, seek opportunities that give you a real chance to lead, implement and work with others towards a commong goal.
Do not get preoccupied with positions and titles. These do not "fool" scrutinizing selection committees.
