The final part of the program was held at UEFA headquarters in Nyon, Switzerland, where both successfully completed the required tests and assessments, confirming the progress they had made during several months of education and training.

The UEFA CORE program is designed to develop referees through intensive theoretical and practical work. During the program, Ljajić and Stjepanović worked on match and refereeing-decision analysis, improving the technical and tactical aspects of refereeing, physical preparation, and developing the skills required to officiate at the highest level. Continuous monitoring of their work, professional analysis and individual guidance from UEFA coaches and mentors were particularly important elements of the program.

Through their participation in the program, Nihad Ljajić and Dejan Stjepanović represented referees from Bosnia and Herzegovina, gaining valuable international experience and knowledge that will benefit their further professional development.

Successfully completing the UEFA CORE 63 program is an important step in their refereeing careers and also confirms their commitment to continued development and achieving the high standards of European football refereeing.
