The First Affirmative Constructive, or 1AC, is the first speech of the debate. Here, the Affirmative (Aff) presents their case. In high school, this speech is 8 minutes long (as are all constructives), while in college it is 9 minutes long (as are all constructives).
The Aff will present several advantages usually (advantages are arguments in favor of their plan or advocacy). These will have numerous cards, or pieces of evidence from qualified sources in support of the position.
