Although assessment is the central skill of applied psychologists and the foundational basis for research and practice, evidence-based assessment (EBA) has lagged behind other domains within the evidence-based movement. Therein lies the importance of this issue, about which we are grateful for the opportunity to provide comments. Overall, the articles in this issue provide a broad overview of EBA within four areas of applied assessment: children and adolescents, medical settings, treatment planning, and forensic settings. The articles collectively review the history of applied assessment in each area, current standards of EBA, and directions for expansion toward a more evidentiary approach. As a collection, this issue provides a very nice sampling on a series of four excellent articles that set the stage for EBA in a variety of settings and contexts.We have organized this commentary around two sections. First, we discuss two important general themes that arose during our readings of these articles, which we believe to some degree will also dictate how EBA and its practice can further evolve. Second, we discuss some important considerations that pertain particularly to the four articles (and thus, the four EBA contexts) in this special issue.
