High School 9:12 believes that leadership is the key to success. The John Donahoo Jr High School 9:12 Leadership Academy was created to provide high school students with an experience of a lifetime. We have partnered with schools from all over Jacksonville, FL to provide selected students with an exclusive lesson taught by author Jack William on how to become a confident, competent, and effective leader. Students will have a full day of learning and collaborating with students from different schools. Every student will receive a certificate of completion at the end of the day.
