为了阅读的目的，两种常用的测试类型来评估词汇知识是大小和水平测试。本文首先回顾了这类测试的几个常见目的（例如，材料选择，跟踪词汇增长），并为服务于这些目的所需的精度提供了合理的论证。然后分析了现有测试中的三个不准确性来源：在意义识别项目格式下，由于猜测或使用测试策略而高估了词汇知识;在对一个测试一个词族成员的知识的项目做出正确反应时，假设所有词族成员都能接受理解，从而高估了词汇知识;以及目标词的小的随机样本在表示从中抽取它的词的总体时具有的有限精度。本文的结论是，现有的测试缺乏许多特定测试目的所需的准确性，并讨论了未来可能的改进。
Two commonly used test types to assess vocabulary knowledge for the purpose of reading are size and levels tests. This article first reviews several frequently stated purposes of such tests (e.g., materials selection, tracking vocabulary growth) and provides a reasoned argument for the precision needed to serve such purposes. Then three sources of inaccuracy in existing tests are examined: the overestimation of lexical knowledge from guessing or use of test strategies under meaning-recognition item formats; the overestimation of vocabulary knowledge when receptive understanding of all word family members is assumed from a correct response to an item assessing knowledge of just one family member; and the limited precision that a small, random sample of target words has in representing the population of words from which it is drawn. The article concludes that existing tests lack the accuracy needed for many specified testing purposes and discusses possible improvements going forward.
