History
Traditionally, rebuttals were half the length of constructive speeches, 8–4 min in high school and 10–5 min in college. The now-prevailing speech time of 8–5 min in high school and 9-5 in college was introduced in the 1990s. Some states, such as Missouri, Massachusetts and Colorado, still use the 8–4 min format at the high school level.1AC
The First Affirmative Constructive (1AC) is the first speech given in a round, presented by the affirmative team. Nearly every 1AC includes inherency, advantages, and solvency, as well as a plan text, the textual expression of the affirmative policy option. The 1AC is generally pre-scripted before the round.1NC
The First Negative Constructive (1NC) is the first speech given by the negative team and the second speech in the round. It is given by the first negative speaker. The 1NC will generally present all of the major2AC
The Second Affirmative Constructive (2AC) is the second speech given by the affirmative team, the third speech in the round, given by the second affirmative speaker. The 2AC must answer all of the arguments read in the 1NC. If there is time remaining, the 2AC sometimes also includes add-ons, or additional advantage scenarios. If negative arguments are not addressed, they are considered conceded.2NC
The Second Negative Constructive (2NC) is the second speech given by the negative team, the fourth speech in the round, given by the second negative speaker. It is the first part of the negative block and thus will only cover part of the 2AC. Often the 2NC will bring up new arguments, to require the 1AR to cover more arguments in their 5 minutes (6 minutes in college). However, some judges consider it abusive to add new off-case arguments, as the affirmative only has five minutes to respond. It is not inappropriate to ask the judge's view on allowing new arguments in the 2NC; after all it is a constructive speech.1NR
The First Negative Rebuttal (1NR) is the third speech given by the negative team, the fifth speech in the round, given by the first negative speaker. Because it is the second part of the1AR
The First Affirmative Rebuttal (1AR) is the first rebuttal speech given by the affirmative, the sixth speech in the round. The 1AR must respond to the entirety of the2NR
The Second Negative Rebuttal (2NR) is the fourth and last speech given by the negative team. It is the seventh speech in the debate, given by the second negative speaker. The 2NR will often take the remainder of the negative's2AR
The Second Affirmative Rebuttal (2AR) is the second rebuttal speech given by the affirmative, and the eighth and final speech in the round. The 2AR generally only answers the arguments made by the 2NR, going to other flows only when the affirmative believes the negative has made a strategic blunder on that piece of paper. In general, the 2AR may not make new arguments that were not in the 1AR. However, because the negative does not go for arguments that the 1AR had to answer, the 2AR is almost always bigger than the portion of the 1AR it represents. Some arguments are never new, like certain forms of extrapolation from 1AR arguments andCross-Examination Periods
Following each constructive speech, there is a three-minute cross-examination period in which the opposing team questions the team which just spoke. Usually, the cross-examination is conducted by the opponent who will not speak next of the speaker who just spoke, but some cross-examinations are open, that is: either partner may ask or answer questions. However, it is often frowned upon when a partner who is not the previous speaker answers cross-examination questions. Typically the cross examiner and the cross examined will not be allowed to look at each other during cross examination.Preparation Time
In addition to speeches, policy debates may allow for a certain amount of preparation time, or "Alternative Use Time
Some tournaments have neither cross-examination time nor preparation time. Rather, each team is given 16 minutes of alternative use time. Alternative use time can always be used as prep time but after a constructive speech it also doubles as cross-examination time. Thus, if the 2AC needs six minutes to get ready after the 1NC, the first affirmative speaker would get to cross-examine the first negative speaker for those six minutes while the second affirmative speaker is preparing. Alternative use time may not be used for cross-examination after rebuttal speeches.References
