The School of Information and Communications Technology (SICT) is one of the branch schools of Mongolian University of Science and Technology (MUST). As of 2017, the SICT consists of five departments, in which Department of Communication Engineering Technology (DCET) currently offers two distinctive programs for bachelor degrees, i.e. Wireless communications engineering technology (WCET) and Telecommunications engineering technology (TET). In order to cope with the fast developments of information and communications technologies as well as to satisfy the requirements and needs of employers, the Program Educational Objectives (PEOs), and Program Learning Outcomes (PLOs) and curriculum of undergraduate programs have been changed and improved periodically and systematically. Since 2012, Mongolian University of Science and Technology (MUST) has been working with the aim of improving the quality of education and reaching a global educational standard level by intensively deploying an Outcome-Based Education (OBE). In this paper, we address our experience on how to set up an assessment process, and the methods, cycle and expected performance levels of PLOs for undergraduate programs offered by DCET.
