To the maximum extent possible, consensus is helpful. But at critical points in the Task Force deliberations, some alternative to consensus may be necessary. Without such an alternative, the progress of the Task Force is subject to the veto power of a single member who may be pursuing a personal agenda. On the other hand, a Task Force recommendation from a bare majority of members will have little credibility with the superintendent and board. A reasonable rule of thumb for consensus is 80 percent – it isn’t unanimous, but it represents the strong conviction of the vast majority of participants.
