AB  - Far transfer---the application of learning across distant domains---remains elusive in intervention research, and even when it is found, its mechanisms remain unclear or unexplored. This study analyzes data from the Model of Reading Engagement (MORE), a sustained content literacy intervention implemented in Grades 1-3 that demonstrated positive treatment effects on both near transfer reading and far transfer math outcomes in a prior study. Here, we extend the original analysis to examine the potential mechanisms of the far transfer effects previously observed on math. Latent mediation analysis shows that approximately 50% of the treatment effect on Grade 4 math is explained by Grade 3 reading, leaving the remainder attributable to other factors. The indirect effects on math are driven by broad standardized reading measures rather than narrower content-specific reading comprehension or background knowledge, suggesting that interventions targeting broad, cross-disciplinary skills may be most effective for supporting far transfer. Results are robust to high levels of unobserved confounding, alternative mediators representing reading engagement and social-emotional learning, and alternative model specifications. We conclude with a discussion of how the appropriate methodological choices for assessing transfer depend on intervention characteristics and substantive research questions.
