The Ministry of Health of the Republic of Indonesia has developed a COVID-19 prevention poster for use in educational institutions. The poster was pretested to determine the reactions of individuals at educational institutions in Depok City in relation to various aspects of communication, such as attraction, comprehension, acceptability, self-involvement and persuasion. The research was descriptive and qualitative, and informants were selected by purposive sampling. The six research informants were teachers and students from a junior high school and a senior high school. Data were collected by using in-depth virtual interviews, and data were analysed using thematic analysis. According to our findings, both teachers and students found the information, images and words of the poster interesting, while the language and terms used were easily understood. In addition, the information was useful and appropriate to the situation and needs. However, titles should be more attractive and specific. In conclusion, according to the input from teachers and students, the COVID-19 prevention poster for educational institutions needs minor revisions. An additional recommendation was that the Indonesian Ministry of Health logo should be added to confirm the source and credibility of the poster.
