Educational technology (EdTech) integration in primary schools has gained attention globally for its potential to enhance learning outcomes and student engagement. A comprehensive search strategy was employed across multiple databases including ERIC, PubMed, and Google Scholar. Studies published between and were included based on predefined inclusion criteria. The analysis revealed a moderate increase (p=0.04, CI: [0.08, 0.16]) in student test scores when EdTech was integrated into the curriculum compared to non-integrated classrooms, with adoption rates ranging from 52% to 78% across different schools. EdTech integration showed promise in improving academic performance and student interest, though variability exists between schools based on resource availability and teaching practices. Further research should explore the long-term effects of EdTech and identify effective strategies for maximising student engagement and teacher training to support these technologies. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
