Artificial Intelligence (AI) technologies are rapidly advancing and increasingly integrated into both professional and daily life. AI plays a transformative role in various sectors such as education, healthcare, and economics, reshaping social structures and practices. Therefore, it is essential for individuals to develop AI literacy in order to understand AI technologies, use them ethically and effectively, and avoid potential disadvantages. AI literacy encompasses understanding fundamental AI concepts, knowledge of its working principles and techniques, and the ability to critically evaluate AI-generated information and transform these technologies into tools for social benefit. High school students constitute a critical group in acquiring AI literacy, as they will shape the future workforce influenced by AI technologies. This study aims to evaluate the AI literacy levels of high school students, examine their perceptions of AI, and raise awareness regarding the use of AI in education. The research was designed using a quantitative cross-sectional survey model. Data were collected through an online scale from high school students enrolled in four different school types in Eskişehir, Turkey: one vocational high school, two project-based public high schools, and one private high school. Preliminary findings indicate that AI literacy levels differ significantly according to school type, gender, and grade level. Vocational high school students were found to require greater support in AI awareness, while 12th-grade students should be further supported in the context of university preparation. The findings are expected to contribute to the safe, ethical, and effective use of AI applications among students and to promote AI literacy awareness.
