Numerous international and national documents highlight that higher education institutions should provide qualified educators and promote the professional development of teachers with a particular focus on student-centered learning and teaching. In the higher education system of the Republic of Croatia, most teachers do not receive specialized training in teaching competencies. While they possess the necessary professional expertise in their respective subject areas, they often lack the pedagogical and andragogical training required for effective higher education. Hence, the authors of this work aim to demonstrate the necessity of continuous education for civilian-military teachers in a certified program for lifelong development of teaching competencies. The continuous education will be delivered through specially designed courses and will be a prerequisite for assuming teaching responsibilities and advancing into scientific-teaching positions.
