OECD经合组织：2025年早期教育与儿童福祉研究结果报告（英文版）

The OECD International Early Learning and Child Well-being Study (IELS) is comparative survey that assesses how children are faring at age five. IELS provides evidence to help policy makers, education leaders and early childhood practitioners in improving young children’s experiences and outcomes. IELS measures multiple domains of children’s early learning and development and collects a range of contextual information from their parents and teachers.
