However, many of these programs rely heavily on external coaches and monitoring teams, raising the question of whether their effects can survive delivery through a country\u2019s own, more limited administrative capacity. This paper provides experimental evidence on this question, evaluating a comprehensive early-grade reading intervention in Haiti, a low-income country with limited government capacity, that combined teacher training, coaching, supervision, and school supplies. To directly test whether the model can be delivered without external coaches, we randomly assigned schools to a costlier \u201cFull\u201d version, in which external coaches led teacher coaching, or a \u201cLight\u201d version, approximately 20 percent less costly, in which coaching was fully delegated to school principals. By endline, 18 months after the start of the intervention, we find effects of approximately 0.3 standard deviations (SD) on student reading outcomes for both versions. Critically, the Light version\u2014which replaces external coaches with existing school leadership, the hardest-to-scale input in this class of interventions\u2014achieves gains statistically indistinguishable from the Full version across every dimension of learning measured. These findings suggest that reliance on external coaching may not be a binding constraint on scaling comprehensive literacy programs, and point to a practical, lower-cost pathway for delivering sustainable pedagogical support within existing school leadership structures in fragile settings.","geographic_units":[{"name":"Haiti","code":"HTI"}],"keywords":[{"name":"Foundational Literacy"},{"name":"Randomized Controlled Trial"},{"name":"Teacher Coaching"},{"name":"Fragile And Conflict-Affected Settings (Fcv)"},{"name":"Scalability"}],"topics":[{"id":"I21","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Analysis of Education","parent_id":"I2"},{"id":" I25","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Education and Economic Development","parent_id":"I2"},{"id":" O15","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Human Resources \u2022 Human Development \u2022 Income Distribution \u2022 Migration","parent_id":"O1"},{"id":" C93","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Field Experiments","parent_id":"C9"},{"id":" I28","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Government Policy","parent_id":"I2"}],"output":[{"type":"Working Paper","description":"Policy Research Working Paper (PRWP)","title":"Scaling Literacy Instruction In Fragile Settings: Experimental Evidence On Teacher Coaching"}],"language":[{"name":"English","code":"EN"}],"technology_requirements":"Runtime: 2 minutes","disclaimer":"The materials in the reproducibility packages are distributed as they were prepared by the staff of the International Bank for Reconstruction and Development\/The World Bank.
