The 1AC is an entirely canned speech that consists of a few parts — Inherency, Harms/Advantages, and Solvency.
Inherency proves the plan is not being supported (or is not being adequately supported now)
Harms/significance prove that without the plan there will be significant problems. For example, without adopting a new education policy there will be inequality and economic problems.
The plan is the basic outline of what policy the affirmative is arguing should be adopted.
Solvency says that the proposed policy will work to solve the arms.
In Policy debate, each part of the 1AC is supported by evidence that is introduced by tagline — a summary statement — and then supported by evidence.
1AC speakers read the tag lines, at least the author and the date of the evidence (some coaches and judges also insist that the authors(s)’ qualifications are read, and then the underlined portions of the quotation.
Writing a case is a difficult endeavor, and many novices will simply use a speech (referred to as a “case”) that their varsity team mates or coaches prepare for them. This is okay to get started, but all novices should keep a few things in mind.
Practice the case before the first tournament. If you don’t at least practice your case and finish it on time in your speech, you will appear unprepared. Judges know that you are a beginner and that debate is hard, but they will expect that you have at least practiced your case.
