We describe the first stage of a longitudinal research program concerned wi
th the prediction, understanding, and durability of early displays of leade
rship behavior. The predictability of teachers' ratings of leadership behav
ior for 242 high school students was explored with respect to predictors fr
om the following construct domains: personality, interests, motivation, beh
avior, self-rated skills, and academic ability. Results revealed that varia
bles from each construct domain significantly and consistently predicted le
adership ratings for as long as 12 months after the collection of the predi
ctor data. In addition, the linear combination of predictors from different
domains yielded strong prediction of leadership, with R(2)s in the .40 ran
ge. Evidence also showed that both academic ability and the other measured
constructs contributed unique variance to the prediction of leadership beha
viors as reported by the teachers. These exploratory findings are discussed
in light of a continuing research program designed to develop a more compr
ehensive understanding of the origin, development, and emergence of adult l
eadership behavior.
