Summary

The implications of various time limits for tests of a fixed length or number of items seem obvious. If the time permitted is much too short, scores may bunch up at the low end of the potential score range, with a loss of potential variance and a general diminishing of the utility of the variance which is observed. If the time permitted is an intermediate value, the scores tend to become some mixture of power and speed. This paper proposes a simple technique for estimating the mean and standard deviation of the distribution of finishing times for a population of test takers. Given such values, a number of decisions concerning test specifications can be made. (Author/DEP)
