Reviewed by: College Student Leadership Development by Valerie I. Sessa Paige Haber-Curran College Student Leadership Development Valerie I. Sessa New York, NY: Routledge, 2017, 213 pages, $49.95 (softcover) Informed by her research on college student leaders, Valerie I. Sessa focuses College Student Leadership Development on how students can learn leadership and develop as leaders. The book serves as a resource to college students, providing a learning model for intentionally guiding one's leadership development. In acknowledging that many skills-based models of leadership exist, Sessa aims to focus less on what one should learn (i.e., skills and behaviors) and more on how one can learn leadership. Sessa has a background in industrial and organizational psychology and has experience as a faculty member in academia, a research scientist and director at the Center for Creative Leadership (CCL), and an organizational consultant. The definition of leadership presented in the book, "accomplishment of three tasks: direction, alignment, and commitment" (p. xiv), is influenced by the CCL's approach to leadership. This definition allows for individuals, regardless of whether or not they hold a positional role, to participate in the tasks of leadership through developing direction and vision, working together through alignment, and committing to the vision by making it a priority. [End Page 255] The author bases this book on research she and her colleagues conducted on college student leaders (Sessa, Morgan, Kalenderli, & Hammand, 2014). In their study, Sessa et al. (2014) sought to extend research on the leadership competencies and skills learned by successful business executives, which was conducted by CCL researchers in the 1980s (Lindsey, Homes, & McCall, 1987), by replicating the study with college students. The study focused on key developmental events that college student leaders said they experienced and key learning lessons gained from these events. Such events included tackling challenging assignments, receiving mentorship, taking a leadership course, and engaging with peers. The first three chapters in the book set the foundation of learning and leadership for the rest of the book by introducing the reader to the concept of leadership and helping the reader connect with the topic, presenting key fundamentals about learning and specifically learning leadership. Sessa emphasizes four leadership learning outcomes: learning about oneself as a leader (i.e., leader identity); learning about different ways to think about leadership and leaders, learning key leader skills and competencies, and learning formal leadership knowledge (i.e., models, theories, language). The next five chapters are framed around the ReAChS model for leadership development, which includes the four components of reflection, assessment, challenge, and support. Sessa developed the model by integrating components of CCL's Assessment, Challenge, and Support Model of leadership development (McCauley, VanVelsor, & Ruderman, 2010) and a systems analysis organizational learning model that she and a colleague developed (London & Sessa, 2006). The ReAChS model is meant to be a tool for students to "take control of [their] leadership learning and development while in college and beyond" (p. 38) and includes four components. Reflection focuses on stepping back from an experience in order to examine it and make meaning of it. Assessment involves learning more about oneself including one's strengths, developmental needs, leadership effectiveness, motivation, self-efficacy for leadership, and personality or character traits. Challenges are described as "learning triggers" that are new experiences requiring skills or perspectives that haven not yet been used or developed. Support focuses on the network of people who can assist in one's learning process. The ReAChS chapters include a range of reflection prompts, exercises, self-assessment exercises, and other tools. These interactive components invite readers to make meaning of their experience, personalize the content, and consider how they can intentionally craft their leadership development journey. There are also many examples from student leaders and excerpts from Sessa et al.'s (2014) research. The book closes with a chapter on synthesizing and communicating one's leadership story. Sessa provides guidance on creating a leadership learning and development portfolio that includes many components such as accomplishment stories; verbiage about jobs, positions, experiences to highlight on a resume; and a personal statement on leadership. The hands-on and interactive exercises can help readers better understand their own leadership learning and effectively communicate...
