This research explores the role of early supervisory experience and co
gnitive ability in first-line supervisor performance. Similar to E L.
Schmidt, J. E. Hunter, and A. N. Outerbridge's(1986) study of nonsuper
visors, this research tested structural models hypothesizing relations
hips among supervisory experience, cognitive ability, supervisory know
ledge and proficiency, and performance ratings, using a sample of 570
second-tour soldiers. The Schmidt et al. model with an additional abil
ity - experience path provided the best fit. The significant ability -
-> experience path was interpreted as indicating that demonstrated abi
lity contributes to soldiers being given the opportunity to obtain sup
ervisory experience. Experience had a greater impact on supervisor pro
ficiency than on superviSor knowledge. Ability had a greater impact on
supervisor knowledge than on proficiency. Discussion focuses on the p
ersonal characteristics that might be involved in being assigned super
visory responsibilities.
