This special issue offers five articles that contribute new insights for officer selection and classification. This commentary connects these articles to historical antecedents and describes their contributions to a better understanding of officer performance. As a set the articles reflect several perspectives, particularly multitrait and multistage models, which have emerged in recent research on individual differences and leadership. This commentary describes the findings from these studies within the context of these perspectives. It concludes with two considerations for future research: A need to focus on (a) officer attributes that relate to adaptability and (b) attributes that foster an enduring ability and motivation to learn, particularly when assessing potential for higher Army ranks.
