In this paper, we address the problem of an educational gap existing between high schools and universities: many students consider their choice of field of study as inappropriate, mostly due to insufficient information regarding the discipline and the university educational process. To solve this problem, we define an innovative, information and communication technology-supported educational process enabling various ways of collaboration between high schools and universities. The goal of that process is to increase the knowledge of prospective students regarding the next level of their education. We propose an environment for the implementation of the educational process. The concepts have been verified in practise as part of the Malopolska Educational Cloud project across several disciplines. We discuss the achievements of the pilot phase of the project as well as its reception by educators and students. Based on evaluation reports and opinions from both educators and students, we claim that the proposed model for information and communication technology-supported collaboration between high schools and universities can effectively reduce the educational gap.
