OBJECTIVES: Delayed child skill development is a common phenomenon in low- and middle-income countries. Effective and low-cost strategies suitable for application to less-developed countries are needed. We summarize empirical findings from recent papers that study a replication of the Jamaica Reach Up and Learn home visiting program in China, China REACH, and compare child skill growth profiles in the China Reach Up and Jamaica interventions. METHODS: Different interventions often use different measures for assessing early childhood skill development. To estimate the growth of underlying skills across programs, we address the challenge that different programs use different assessments. We use a modified version of the Rasch model to anchor scores on common items to estimate skill development. RESULTS: Language skill growth curves are comparable for both interventions. This pattern is consistent for the treatment and control groups across the interventions. Skill growth curves are not statistically significantly different between China REACH and Jamaican interventions. We find evidence of the importance of early investment. CONCLUSIONS: The China REACH intervention significantly improves the development of multiple skills. At the same ages, treatment effect sizes and skill growth curves are comparable across the Jamaica and China REACH interventions, despite differences in scale and cultural settings. The scale of the program is much greater in China than in Jamaica, showing that the Jamaican curriculum can be effectively expanded to larger populations. Annual costs per child are roughly $500 (2015 US dollars). [ABSTRACT FROM AUTHOR]
