Increasingly, states establish different thresholds on the Early Childhood Environment Rating Scale-Revised (ECERS-R), and use these thresholds to inform high-stakes decisions. However, the validity of the ECERS-R for these purposes is not well established. The objective of this study is to identify thresholds on the ECERS-R that are associated with preschool-aged children's social and cognitive development. Applying non-parametric modeling to the nationally-representative Early Childhood Longitudinal Study Birth Cohort (ECLS-B) dataset, we found that once classrooms achieved a score of 3.4 on the overall ECERS-R composite score, there was a leveling-off effect, such that no additional improvements to children's social, cognitive, or language outcomes were observed. Additional analyses found that ECERS-R subscales that focused on teaching and caregiving processes, as opposed to the physical environment, did not show leveling-off effects. The findings suggest that the usefulness of the ECERS-R for discerning associations with children's outcome may be limited to certain score ranges or subscales.
越来越多的州在修订后的《幼儿环境评价量表》(ECERS-R)上设定了不同的阈值,并使用这些阈值来做出重大决策。然而,ECERS-R用于这些目的的有效性尚未得到充分证实。本研究的目的是确定ECERS-R上与学龄前儿童社会和认知发展相关的阈值。将非参数建模应用于具有全国代表性的《儿童早期纵向研究出生队列》(ECLS-B)数据集,我们发现,一旦教室在ECERS-R综合得分上达到3.4分,就会出现平稳效应,即未观察到儿童的社会、认知或语言成果有进一步改善。进一步分析发现,与物理环境不同,侧重于教学和照顾过程的ECERS-R子量表未显示出平稳效应。研究结果表明,ECERS-R在识别与儿童成果的关联方面的有用性可能仅限于特定的分数范围或子量表。
