We are surrounded by a variety of leadership assessment tools - self-assessments, 360-style evaluations, personality tests - all designed to help you understand your leadership style and identify areas for potential improvement.  But are these assessments all they are cracked up to be, and if so, when and how should they be used effectively?  And what type of leadership assessment should be used in different situations?  Father-and-son duo Tony and Alan Jackson discuss the world of leadership assessments available in this month's episode of "Leadership GPS". Tony Jackson is a leadership development consultant and coach, helping organizations turn some of their strongest people into future leaders.  For more information on Tony and his leadership development program, visit DriveLeadership at www.driveleadership.com.
