# Enhancing Rural Children’s Cognitive Abilities Through Teacher Support: Quasi-Experimental Evidence from Longitudinal Data in China

## TL;DR

This study finds that teacher support in rural China improves children's cognitive abilities, especially for girls and those from poor families.

## Contribution

The study provides quasi-experimental evidence linking teacher support programs to cognitive gains in rural children.

## Key findings

- Exposure to the Rural Teacher Support Program improved cognitive abilities by 0.19 standard deviations.
- Benefits were stronger for female students and those from low-income households.
- Improved teacher quantity and student satisfaction mediated the positive effects.

## Abstract

This study leverages longitudinal data from the China Family Panel Studies (CFPS, 2012–2020) to examine the association between teacher support and cognitive ability among children aged 10–16 living in economically disadvantaged rural areas of China. Employing a difference-in-differences (DID) framework, we found that exposure to the Rural Teacher Support Program (RTSP) is associated with an improvement of about 0.19 standard deviations in students’ cognitive abilities after accounting for individual-, family-, and county-level characteristics. Two key mechanisms appear to underlie this association, reflected in increased teacher quantity and enhanced student satisfaction with teachers. Heterogeneity analyses further show that these benefits are more pronounced among female students and those from low-income households, suggesting that teacher-centered institutional improvements may help mitigate developmental disparities. Overall, the longitudinal results indicate that better teacher-related environments are likely to support children’s cognitive development, which in turn may help reduce educational inequality in under-resourced areas.
