About the League

Our mission

To grow accessible, high-quality competitive debate, and to run tournaments that students, coaches, and judges can trust.

The Tri-State Debate League (TSDL) is a nonprofit dedicated to competitive middle and high school speech and debate across New York, New Jersey, and Connecticut. We believe debate is one of the most valuable activities a student can take part in: it builds research, argumentation, public speaking, and critical-thinking skills that last well beyond high school.

We hold ourselves to high standards of fairness, transparency, and organization at every event we run.

What We Do

Our three commitments

  • Run excellent tournaments that students, coaches, and judges can trust.
  • Develop the people who make the activity possible.
  • Lower the barriers that keep schools and students out.

Our Reach

Schools we've served

More than fifty programs across the New York metro area have competed in TSDL tournaments, independent, public, charter, and religious schools from Manhattan, the Bronx, Brooklyn, and Queens, out to Westchester, Long Island, the Capital Region, and New Jersey, along with a growing group of private debate academies.
