World Class Faculty
Lumos Debate recruits instructors who are the best at what they do. Many are experts in debating who’ve had incredible success in debate, placing at and winning multiple national debate titles and earning numerous speaker awards. Others are champions in speech and experienced with theatre, with a focus on body language, projection, and tone. Yet other instructors specialize in working with children – many have multiple years of experience teaching and coaching students to tournament wins. Every single Lumos Debate instructor is phenomenal, and that means you can be absolutely certain your child is going to receive phenomenal coaching.
In all of our programs, we guarantee a 6:1 student-instructor ratio. This extraordinarily low student-instructor ratio allows us to constantly break out into small discussion groups, and our expert instructors provide one-on-one feedback and mentorship for your child every single day.
