The National Board of Veterinary Medical Examiners was interested in the possible effects of word count on the outcomes of the North American Veterinary Licensing Examination. In this study, the authors investigated the effects of increasing word count on the pacing of examinees during each section of the examination and on the performance of examinees on the items. Specifically, the authors analyzed the effect of item word count on the average time spent on each item within a section of the examination, the average number of items omitted at the end of a section, and the average difficulty of items as a function of presentation order. The average word count per item increased from 2001 to 2008. As expected, there was a relationship between word count and time spent on the item. No significant relationship was found between word count and item difficulty, and an analysis of omitted items and pacing patterns showed no indication of overall pacing problems.
美国兽医医学考试委员会对字数对北美兽医执照考试结果的可能影响感兴趣。在本研究中，作者调查了增加字数对考试各部分考生答题节奏以及考生在题目上表现的影响。具体而言，作者分析了题目字数对考试某一部分内每道题平均花费时间、该部分末尾遗漏题目的平均数量以及题目平均难度（作为呈现顺序的函数）的影响。2001年至2008年期间，每道题的平均字数有所增加。正如预期的那样，字数与答题时间之间存在关联。未发现字数与题目难度之间存在显著关系，对遗漏题目和答题节奏模式的分析也未显示出整体答题节奏问题的迹象。
