This study assesses the psychometric properties of the School Support Scale (SSS), part of the CHKS's Resilience Youth Development Module (RYDM; Furlong et al., 2009), among 231 sixth- and seventh-grade students in urban public schools in Chile. Results indicated satisfactory psychometric properties, replicating a unifactorial structure observed in prior research (Hanson & Kim, 2007), where items related to caring relationships and high expectations loaded onto a single factor, school support. Significant correlations were found with measures of life satisfaction and school-related affect. These findings underscore the scale's utility in evaluating student perceptions of school support and highlight avenues for future research to enhance its applicability across diverse educational contexts.
