Educational integration and inclusion respects the fundamental principle of educational systems, according to which all children should study together. The institution oriented towards inclusive education values differences for the benefit of all children, recognizes their various needs and seeks solutions for each of them, taking into account different learning rhythms and styles. The inclusive institution thus ensures equal opportunities for all children valuing and respecting their differences and fighting against discrimination and prejudices by means of appropriate educational policies and practices. The transformation process of a traditional school to an inclusive one requires time and new techniques of management from each teacher. Professional development of teachers in order to support inclusive education includes both initial training as well as continuing training throughout teaching career.
