Results are expressed as mean and standard deviation of scores obtained in pre- and post-tests. Significance obtained using paired t-test
SD standard deviation
*All paired t-tests were highly statistically significant at a p-value of < 0.0001Kenya’s pre- and post-tests were distributed by module, not as a singular cumulative test post-exposure to all modules
