ICT platforms have been introduced to improve educational outcomes in developing countries, including Uganda. A randomized controlled trial was conducted with 500 participants across three schools. Pre- and post-intervention assessments were used to measure student performance in mathematics and science subjects. There was a statistically significant increase (p < .05) of 12% in average test scores for students who received the ICT intervention compared to controls, with confidence intervals ranging from 7% to 18%. The study also identified themes such as improved engagement and reduced absenteeism among participants. The use of ICT platforms significantly enhanced academic performance among Ugandan junior high school students over a two-year period. Schools should continue to integrate ICT resources into their curricula, with ongoing professional development for teachers to maximise the benefits of these tools.
