Dover High School Principal Courtney Voshell believes that the key to success for any school leader is to always remember that they are still teachers and to never forget that all teachers need support and feedback.


In 2010, during Voshell’s first year as assistant principal, Dover High School was labeled a failing school. As a new administrator, Voshell harked on her years of teaching experience at the school to provide insight from a teacher’s perspective and share ideas on how she thought the school could improve. She led the implementation of professional learning communities at the school to help teachers collaborate and share best practices and organize data to make data-driven decisions.


As part of her strong belief in the power of personalization in schools, Voshell makes sure to connect with teachers and students by completing weekly walkthroughs, where she provides instructional feedback to teachers and interacts and works with students on their classroom activities.  These walkthroughs are just one example of Voshell’s commitment to maintaining an instructional focus as an assistant principal, regardless of the many administration duties that often make that a challenge.


In the two full school years since Dover High School was labeled a failing school, Voshell has helped the school get back on track and meet all student targets on both state assessment and graduation cohort.


“Using her natural leadership style, and her creativity, Dr. Voshell created reforms that addressed in positive and enduring ways many school-wide problems such as at-risk students and those ever-so-important teacher evaluations,” said Dover High School Principal Evelyn Edney. “She has helped the staff establish academic, career and technical, and school climate means to meet the goal of increasing student achievement [and] Dr. Voshell has done wonders for raising student achievement.”
