The debate rules also provides for direct questioning, if the standing rules of the organization allow for it, where the speaker and questioner can engage in direct dialogue without moderation from the chair. This is done in 30- or 60-second blocks of time, allowing the questioner to engage the floor speaker to greater depth. This is used to sometimes build arguments that the questioner uses in a later speech, similar to cross-examination in other competitive debate events. At tournaments where this is practiced, the presiding officer is either required or strongly advised to keep a separate questioning priority, to ensure equal opportunity for questioners. Several tournaments have piloted this method since the National Speech and Debate Association suggested this as a result of discussions with its Congressional Debate Rules and Recommendations Committee in 2009.
