About DDI and DDIx


The DDI is a program for experienced policy debaters with at least a full year of high school policy debate experience. Now in its 36th year, the DDI has produced national champions at the high school and collegiate level. Most attendees are entering their junior or senior year; it may be appropriate for sophomores with a strong record.

2020 Testimonials

“Thank you for making my last debate camp…being online so enjoyable. I learned a lot and will forever be grateful to the DDI program. DDI gave me a huge passion for debate and I couldn’t have imagined attending another institute. DDI has inspired me throughout my career to produce the best arguments possible…I owe so much to this camp.”
-Ella Laurent – Cypress Bay High School

“DDI was by far my best camp experience, and I’m so glad to have had the opportunity to attend, even if it was via Zoom…I’ve come out a much stronger strategist, team worker, and researcher. The series of lectures/aff discussions/speech redo feedback sessions would have been painstakingly long at any other camp, but the AT lab leaders made each the best 4-5 hours possible…The culture of our lab was always centered around cooperation and discussion, and all three lab leaders were always available after lab to discuss strategy thoughts, look over cards, etc. which made it feel more like a friendly coaching environment.”
-Emily Feng – Interlake High School

“I really felt like KM lab was family by the last week and I’m glad that we were able to form close bonds while also putting out high quality work.”
-Richard Liu – Little Rock Central High School

“I chose DDI because I wanted to have a rigorous research experience and learn about a wide array of arguments. My lab leaders were incredibly accessible and gave detailed feedback that was applicable to larger trends in my approach to debate.”
-Dana Agbede – Downtown Magnets High School

“I chose DDI for the staff, which was a decision I came to really be happy with. My hope going in was that all the staff would be accessible and I could pick their brains inside & outside of lab, which I definitely could and did.”
-Holland Bald – The Westminster Schools

DDIx is two week policy debate program that provides intensive skills work. The DDIx curriculum focuses on debate practice rather than research. Students will have daily practice debates as well as a small tournament at the end of the program. The program is open to rising sophomores, juniors, and seniors. Most students who attend the DDIx choose to also attend the DDI and the programs are intended to complement one another, but students also have the option of attending the DDIx alone.

“I absolutely loved my lab, it was incredibly helpful, helped my debate style, they are great teachers and work very well together. … I had a great time, learned a lot, and can’t explain how much I appreciate the experience. I met amazing people, learned from all of the staff, and can honestly say I grew as a debater. … The first week I learned and tested policy skills … DDIx was amazing, I learned a lot, got my toes into the topic.”
