In 2020, LARA undertook an analytic research into the contextual factors impacting reading outcomes. This research involved a review of the existing literature on the contextual factors affecting reading outcomes and a secondary analysis of existing datasets collected as part of the monitoring and evaluation activities of LARA and SHRP. The study team conducted multi-variate analyses to determine what contextual factors predict student learning outcomes. These were grouped into the three categories: (1) school, classroom, and system; (2) teacher characteristics and instructional practices; and (3) learners and home environment. Although the analyses included demographic factors, such as socioeconomic status, the focus in the report is on predictors of learning outcomes that could be controlled by education programs. The report also provides implications of the findings and recommendations for future education programming.
