The diversity curriculum “We All Smile in the Same Language” was implemented at Camp Lesnaya Skazka in Mari El, Russia. The curriculum aimed to increase knowledge about diversity among campers ages 8 to 16. The evaluation is based on a review of the literature and analysis of a 20-question survey administered pre- and post-intervention. The evaluation sought to determine the impact of the curriculum on diversity awareness and self-esteem in campers ages 9 to 12. While the results were not statistically significant, the analysis contributes to improving the program and provides ideas for future design of international diversity education programs for children.
