In modern society, information has become a measurable product. Every social activity is conditioned by information, which should be true and reliable. Internet technology - having become an infinite source of information - does not provide any credibility in terms of information reliability, so the individual is expected to independently take care of it. Essential to such conditions are information competencies, which determine the ability to define the information needs necessary to accomplish tasks, and the effective and responsible gathering of reliable information. The obvious challenge for modern education is therefore to shape and develop information literacy at all its levels. To make this possible, information literacy must become an absolutely indispensable attribute of each teacher. The presented text is empirical and is an attempt to answer the research question: To what extent do teachers' information competencies affect the adaptation of education to technologically conditioned social changes? The research was carried out at the Pedagogical University in Cracow. Students - candidates for the teaching profession, took part in the study.
