Child abuse is underreported for children with socioeconomic inequalities. The impact of geographic location combined with sociocultural characteristics on teachers’ reports of child abuse remains unclear. A national survey of 572 kindergarten teachers from 79 schools in Taiwan used hierarchical linear modeling to investigate the contribution of individual factors, environmental factors, and training on kindergarten teachers’ intention to report child abuse. In-service training had the most influence on teachers’ intention to report in eastern Taiwan, the poorest and least-educated region. Training programs should be designed based on socioeconomic and cultural contextual needs.
