    This report presents the findings of an independent impact evaluation of the Jolly Phonics and Grammar programmes in Namibia, commissioned to assess the programme’s effectiveness in improving foundational English reading skills among early-grade learners. The evaluation focused on Grade 3 learners from the 2024 academic year, sampled from 100 schools equally divided between the Oshana region (which had been trained on Jolly Grammar 2 for Grade 3s) and the Oshikoto region (which had not received Jolly Grammar 2 training at the time of the survey). The study employed a Propensity Score Matching (PSM) approach to estimate average treatment effects on Early Grade Reading Assessment (EGRA) performance. Four primary models were employed, varying in their matching specifications to test the robustness of results. The evaluation also calls for improved monitoring and the incorporation of longitudinal study designs, including baseline assessments, to better track learner progress over time and attribute improvements to the Jolly programmes
