Background Although epilepsy is a common disorder, it is highly stigmatized. Not only public but even teachers are not free from stigmatization and cultural barriers. Under this condition, children with epilepsy are more vulnerable for stigmatization, social isolation, lack of support, and psychological and emotional problems. At the same time, there is an immediate need of literature focusing on intervention studies to change the attitudes of school teachers and children. Materials and Methods The study was conducted with the objectives to evaluate knowledge, attitude, and practices about epilepsy among school teachers and children; provide educational training program to teachers; and check the efficacy of training program imparted by teacher and trainer. Results Repeated measure of analysis of variance shows that knowledge ( F = 1134.875, p < 0.001), attitude ( F = 2429.909, p < 0.001), and practice ( F = 2205.122, p < 0.001) are significantly different between pre- and posttest indicated by Pillais trace test. Similarly, from the Pillais test knowledge ( F = 49.317, p < 0.001), attitude ( F = 125.304, p < 0.001) and practice ( F = 178.697, p < 0.001) are significantly different among the teachers, trainer imparted training group of children, and teachers imparted training group of children groups. It is seen that knowledge, attitude, and practice scores significantly differ between two time points and across three groups. Among all the groups, teachers imparted training group children had high level of practice. Conclusion Inclusion of health education programs in the textbooks and health education schemes for teachers and school children is a crucial way to bring a change in their attitude, behavior, and practices.
