An overview of relational-cultural theory and Relational-Cultural Therapy (RCT) is provided. First, a summary of the overarching framework for relational-cultural theory is offered. The theory's roots in feminist and psychodynamic theories are discussed, along with distinguishing aspects of relational-cultural theory. The practice of RCT is reviewed, including research support regarding assumptions, practice applications, and effectiveness. The unique role that teaching RCT can play in building counseling competencies is explored with a focus on competencies related to therapeutic relationship-building skills and awareness of individual-cultural diversity. It is contended that RCT can provide an organized, systematic structure for the development of therapeutic relationship-building skills and a framework on which to build when asking counseling trainees to reflect on issues of power, privilege, oppression, and marginalization, including the ways in which those issues influence counseling. Specific examples are provided to illustrate the application of RCT in fostering these counseling competencies.
