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…

The use of indices of speededness in tests is reviewed and three possible indices which derive from a model which assumes that rate of work is normally distributed is proposed. Each of these indices is seen as limited by the failure to adequately consider the correlation between speed and power, but they have the advantage that they are derivable…

To evaluate test speededness and to derive implications for test program activity, this document presents an annotated bibliography on studies of test speededness. The 64 citations range from 1902 to 1976, and include the seminal articles by Cronbach and Warrington (1951) and Gulliksen (1959); articles which summarize the previous literature on…

To evaluate test speededness and to derive implications for test program activity, this study reviewed the literature on speed and power, identifying four major approaches to the assessment of speed: the Gulliksen approach, the Cronbach and Warrington approach, the Stafford approach, and the approach of the Educational Testing Service (ETS) as…

Questions are raised about the time within a test administration period that may be available for review for those candidates who have time enough, or more than enough, to finish. The assumption is proposed that rate of work may be normally distributed. The rate of work for those who have finished a test cannot be determined from their answer…
