This study evaluated the validity of self-assessment in a natural setting. It also addressed the possibility of improving the utility of self-assessment by cautioning subjects that their responses could be compared with other existing data on them. Subjects were 357 males, aged 18-19 years, who were being screened for a prestigious military course. During the screening, they participated in small groups for nine days of tests, class exercises, and field simulations supervised by veteran commanders. On the ninth day, ratings were collected from commanders, peer group members, and the subjects themselves on dimensions related to eventual success in the training course. The experimental group was told their reports would be compared with those from other sources; the control group was not. Predictive and convergent validities were examined on three criteria: course success, commander ratings, and peer evaluations. Selfassessments from both experimental and control group were valid however, those of the experimental group did not yield consistently higher validities. Findings are discussed in regard to their practical ramifications. Although self-assessments are often thought to have little veracity, there is reason to argue that individuals are often in the best position to validly assess their own abilities and behaviors and to predict their subsequent conduct. Theories of self-perception (Jones & Nisbett, 1971) have noted that one has access to wide samples of behaviors under varying situations and periods of time. Moreover, one has unique acquaintance with one's own inner states, feelings, and dispositions, as well as with their changes over time. Further, empirical research has demonstrated that individuals are more sensitive than external observers to situational determinants of their behavior and are less likely to overattribute the outcomes of their actions to dispositional factors. Finally, other individuals provide valuable information about actors' behavior. People are continually observing others and comparing themselves with others, as social comparison theories (e.g., Rstinger, 1954) have argued. Levine (1980) summarized the advantages of actors assessing themselves, saying: "we all have a good deal of time to The authors would lie to thank Dr. Michael Hoffman for his valuable contribution.
