The six statewide research studies presented in this special issue use a variety of designs, instrumentation, and measures. Nevertheless, they can be integrated at the level of results to shed light on some important questions related to effective practice in the field of school counseling. In fact, one can argue that, when separate studies that are conducted in a variety of contexts achieve similar findings, greater confidence can be placed in the conclusions. These six studies provide valuable evidence of the relationship between positive student educational outcomes and school counseling program organization, student-to-school-counselor ratios, counselor time use, and specific school counseling activities. Throughout this article, the authors have made suggestions for future research, including the development of reliable and valid measurements of school counseling programming and practices, an increased understanding of the impact of state contexts on school counseling, information about how school counselor education programs are and are not preparing future counselors for the current educational reality, and studies about which specific school counseling practices within the domains identified are most effective.
