Faculty
We pledge to provide our students with exceedingly qualified faculty. Our faculty consists of successful and respected debaters, many of whom have been recognized for their achievements on the National level. They come from different backgrounds, but each has an abundance of insight and knowledge to share.
Our instructors are all Lexington High School alumni with 4-6 years of debate experience. In addition, current members of the debate team support the learning environment as lab assistants. We have a 4:1 student-staff ratio, which allows us to break into small groups and provide direct and targeted feedback for every student.
​
Every single instructor we hire has a unique skillset they have spent their own debate careers honing, and they will be eager to pass it on to your children. Our staff is committed to educating our students about debate in a fun, creative, and engaging way. They have all had extensive experience working with younger students and will go through rigorous training before instructing here to ensure your child has the best and most rewarding experience possible at our Institute.
