Given the importance of math in today’s society, it is critical that children who are at risk for math difficulty are identified early. We developed and validated a prekindergarten math subtest (i.e., CIRCLE Progress Monitoring [CPM] Math Subtest). This teacher-completed measure evaluates domains considered important for later math development. Evaluation of validity was undertaken in a longitudinal sample of 383 children (Mage = 4.9 years), and a follow-up sample of 3,691 children (Mage = 4.4 years). The measure demonstrated adequate psychometric properties, including strong internal consistency reliability (α = .94) and test–retest reliability (r = .78). Evaluation of concurrent and predictive validity demonstrated scores on the CPM Math Subtest were correlated with scores on other assessments at high levels (rs from .55–.65). Exploratory and confirmatory factor analyses revealed that the subtest conforms to a well-defined five-factor model that parallels areas considered to be important in the math literature.

学前班学生数学进步监测措施的初步验证

鉴于数学在当今社会中的重要性，尽早发现有数学困难风险的儿童至关重要。我们开发并验证了学前班数学子测试（即 CIRCLE 进度监控 [CPM] 数学子测试）。这个由教师完成的测量评估被认为对以后的数学发展很重要的领域。有效性评估是在 383 名儿童（法师 = 4.9 岁）的纵向样本和 3,691 名儿童（法师 = 4.4 岁）的后续样本中进行的。该测量表现出足够的心理测量特性，包括强大的内部一致性信度（α = .94）和重测信度（r = .78）。并发和预测有效性的评估表明，CPM 数学子测试的分数与其他高水平评估的分数相关（rs 为 0.55–.65）。
