Before becoming an administrator at Reeds Ferry School (RFS) twelve years ago, Kimberly Yarlott taught at the elementary level for 18 years. In her eight years as principal of RFS, she has leveraged this experience to influence the school’s instruction and assessment practices, mentoring her staff toward increased rigor and differentiation in the classroom. Under her leadership, RFS became an early adopter of PLCs, and teachers continue to use team meetings to develop and implement data and intervention protocols that increase the whole school’s capacity to cultivate not only grade-level competencies, but life-long learning skills for all students. Yarlott’s superintendent calls her a “master teacher and an excellent evaluator,” but her leadership style is humble and collaborative, embracing and seeking out the expertise and experience of her colleagues, teachers, and students to understand problems and seek generative solutions. For example, she recently facilitated an evaluation of science and social studies instruction that led to the creative restructuring of the instructional schedule to protect content areas that previously were not a high testing priority, while still providing rigorous intervention and enrichment in literacy and math. Yarlott is active in district leadership and has taught as an adjunct professor at Southern New Hampshire University and Keene State College. She holds a B.A. from the University of Massachusetts and an M.Ed. and a Certificate of Advanced Graduate Studies from Plymouth State University.
