Dyscalculia affects 3-7% of the world's population. Dyscalculia students will experience a significant decrease in academic achievement. The purpose of this community service activity is to improve the skills of eight teachers of SD Negeri Pisangcandi 3 Malang in recognizing the early symptoms of dyscalculia. The earlier students realize the dyscalculia they are experiencing, the easier it will be to overcome them. The service team used the dyscalculia screening training method in February 2021 online and offline by observing strict health protocols to achieve this goal. The training activity began by giving a questionnaire related to the concept of dyscalculia. Furthermore, at the last training session, the service team gave a different questionnaire with the same topic. The final results of community service activities showed that all training participants had participated in the activities as a whole well. The teacher's understanding can be seen from the increasing score of the questionnaire—the initial questionnaire results with an average value of 57.5 to 79.5 at the end of the training. The initial and final questionnaires contain different questions but are built on the same indicators. Before being used in community service activities, the questionnaire has gone through a validation process by three experts. The results of the service show that the average increase in teacher understanding is 22%.
