The two most commonly used nonverbal tests for gifted identification, the Naglieri Nonverbal Ability Test (NNAT) and the Cognitive Abilities Test (CogAT) nonverbal battery, have not been compared in their newer versions to explore the effects of their use on the identification of underserved populations. Additionally, the effects of the use of various norming groups and cutoff scores on both instruments’ identification abilities has not been compared. This study compared 15,733 CogAT7 nonverbal battery scores and 14,421 NNAT2 scores of kindergartners between 2013 and 2015 from one large urban school district to explore the differences between how each test relates to major demographic variables and examine the effects on who is selected for participation in gifted programming based on which instrument, which norming group, and which cutoff scores are used. Both instruments were less likely to identify students from demographic groups that have been traditionally underrepresented than students from traditionally overrepresented demographic groups, but identification varied based on the type of norming plan used and which instrument was taken. Suggestions are made as to the best instrument for use with various demographic groups and norming plans.

使用认知能力测试 (CogAT) 7 非语言能力测试与 Naglieri 非语言能力测试 (NNAT) 2 识别天才/天才的差异

两种最常用的鉴定天才的非语言测试,即 Naglieri 非语言能力测试 (NNAT) 和认知能力测试 (CogAT) 非语言测试,尚未在其较新版本中进行比较,以探讨其使用对鉴定服务不足者的影响人口。此外,尚未比较使用各种规范组和截止分数对两种工具的识别能力的影响。本研究比较了 2013 年至 2015 年来自一个大型城市学区的幼儿园儿童的 15,733 个 CogAT7 非语言电池分数和 14,421 个 NNAT2 分数,以探索每个测试与主要人口统计变量之间的差异,并检查对选择参与天才编程的人的影响基于哪个工具,哪个规范组,以及使用了哪些截止分数。与来自传统上代表人数过多的人口群体的学生相比,这两种工具都不太可能从传统上代表性不足的人口群体中识别出学生,但识别因所使用的规范计划类型和所采用的工具而异。对用于各种人口群体和规范计划的最佳工具提出了建议。
