Aim: The aim of this prospective meta‐analysis was to synthesize the results of three cluster‐randomized trials of an intervention designed to teach lower‐secondary school students (age 14–16) to think critically about health choices. Methods: We conducted the trials in Kenya, Rwanda, and Uganda. The intervention included a 2‐ to 3‐day teacher training workshop, digital resources, and ten 40‐min lessons. The lessons focused on nine key concepts. We did not intervene in control schools. The primary outcome was a passing score on a test (≥9 of 18 multiple‐choice questions answered correctly). We performed random effects meta‐analyses to estimate the overall adjusted odds ratios. Secondary outcomes included effects of the intervention on teachers. Results: Altogether, 244 schools (11,344 students) took part in the three trials. The overall adjusted odds ratio was 5.5 (95% CI: 3.0–10.2; p < 0.0001) in favor of the intervention (high certainty evidence). This corresponds to 33% (95% CI: 25–40%) more students in the intervention schools passing the test. Overall, 3397 (58%) of 5846 students in intervention schools had a passing score. The overall adjusted odds ratio for teachers was 13.7(95% CI: 4.6–40.4; p < 0.0001), corresponding to 32% (95% CI: 6%–57%) more teachers in the intervention schools passing the test (moderate certainty evidence). Overall, 118 (97%) of 122 teachers in intervention schools had a passing score. Conclusions: The intervention led to a large improvement in the ability of students and teachers to think critically about health choices, but 42% of students in the intervention schools did not achieve a passing score.
