Impromptu
- Impromptu debate is a relatively informal style of debate, when compared to other highly structured formats.
- The topic for the debate is given to the participants between fifteen and twenty minutes before the debate starts.
- The debate format is relatively simple; each team member of each side speaks for five minutes, alternating sides.
- A ten-minute discussion period, "open cross-examination" time follows, and then a five-minute break . Following the break, each team gives a 4-minute rebuttal.
