Abstract
When items cannot be answered correctly by guessing, certain two-stage testing procedures are about as effective over the ability range of interest as the "best" up-and-down procedures studied previously. When answers can be guessed correctly 20 percent of the time, no two-stage procedure is found to match the "best" up-and-down procedures over this ability range. Feet-on-the-desk designs for two-stage procedures may produce poor results.
