调查和量化中度铅暴露对学生在期末标准化考试中获得“熟练”水平分数的影响。我们比较了3757名来自威斯康星州密尔沃基的四年级学生在威斯康星州知识和概念考试（WKCE）中的成绩。样本包括3岁之前进行血铅检测的儿童，这些儿童在检测时无法定量（<5 μg/dL）或处于中等暴露范围（10-19 μg/dL）。在控制了性别，贫困，英语学习者地位，种族/民族，学校纪律处分和出勤率后，结果显示，中度铅暴露对WKCE所有5个分测试的学业成绩有显着的负面影响。测试分数赤字由于铅暴露等于22%的学生分类之间的间隔在“熟练”或“基本”水平的阅读，和42%的间隔在数学。尽管许多州的现行政策规定，3岁前接触铅的儿童在7至8年后与未接触铅的同龄人相比，仍处于相当不利的教育地位。暴露的学生得分低于熟练水平的风险更大，这对学生和学校都有严重的负面后果。
To investigate and quantify the impact of moderate lead exposure on students' ability to score at the “proficient” level on end-of-grade standardized tests. We compared the scores of 3757 fourth grade students from Milwaukee, Wisconsin, on the Wisconsin Knowledge and Concepts Exam (WKCE). The sample consisted of children with a blood lead test before age 3 years that was either unquantifiable at the time of testing (<5 μg/dL) or in the range of moderate exposure (10–19 μg/dL). After controlling for gender, poverty, English language learner status, race/ethnicity, school disciplinary actions, and attendance percentage, results showed a significant negative effect of moderate lead exposure on academic achievement for all 5 subtests of the WKCE. Test score deficits owing to lead exposure were equal to 22% of the interval between student categorization at the “proficient” or “basic” levels in Reading, and 42% of the interval in Mathematics. Children exposed to amounts of lead before age 3 years that are insufficient to trigger intervention under current policies in many states are nonetheless at a considerable educational disadvantage compared with their unexposed peers 7 to 8 years later. Exposed students are at greater risk of scoring below the proficient level, an outcome with serious negative consequences for both the student and the school.
