This paper investigates the level of information literacy among students of Jelkovec High School in Zagreb. A survey was conducted using an online survey questionnaire (open-ended and closed-ended questions). The level of information literacy among students was examined, as well as the existence of differences in information literacy between students of different educational profiles and different ages. The theoretical part of the paper discusses information literacy, models and standards related to information literacy, and analyzes research on this topic. Good collaboration between librarians and teachers and libraries and the environment is needed. Because of its users, the library should research their needs on a daily basis and realize them together, and the person who needs to understand these needs towards the users is the librarian himself. The student is the one who stands out in the first place and who, like everyone else, has his own needs, then he wants to acquire the knowledge and certain skills he needs to better cope in modern society. So, in order for a library to fulfill its tasks, it must provide a space that is user-friendly. It must also, above all, provide them with sources of quality and verified information in order to contribute to the development of curricula and students. All the knowledge that students gain in the library (as individuals or in a group) is for their better future, because with that knowledge they move forward in life.
