Rasch and classification analyses on a field-test version of the Assessment, Evaluation, and Programming System Test—Third Edition (AEPS-3), a curriculum-based assessment used to assess young children birth to age 6 years, were conducted. First, an evaluation of the psychometric properties of data from each developmental area of an AEPS-3 field-test version was conducted. Next, cutoff scores at 6-month age intervals were created and then the validity of the cutoff scores was evaluated. Results using Rasch modeling indicated acceptable model fit statistics with reasonable reliability estimates within each developmental area. Classification results showed cutoff scores accurately classified a high percentage of eligible children. Findings suggest that scores from a field-test version of the AEPS-3 are reliable within developmental areas. To the extent allowed by state criteria, early childhood interventionists could possibly use a new field-test version of the AEPS-3 to determine or corroborate eligibility for special education services.

在“评估，评估和编程系统测试-第三版”（AEPS-3）的现场测试版本上进行了Rasch和分类分析，这是一种基于课程的评估，用于评估6岁以下的幼儿。首先，对来自AEPS-3实地测试版本每个开发区域的数据的心理计量学特性进行了评估。接下来，创建6个月大的间隔分数，然后评估该间隔分数的有效性。使用Rasch建模的结果表明可接受的模型拟合统计量以及每个开发区域内的合理可靠性估计。分类结果显示，截止分数准确地对高比例的合格儿童进行了分类。研究结果表明，AEPS-3现场测试版本的分数在发展区域内是可靠的。
