Students with hearing disabilities need a safe and inclusive environment for full personality development and effective communication. The safe educational environment for training represents for anyone - teaching staff or student with hearing disabilities - a very intense space, with a huge overlap of interactions and challenges. School is not and will not remain a space of academic knowledge, but also one of practical social experiences where through communication students discover, reflect and develop interpersonal relationships. Communication is the essential condition for a cognitive development, and even for a physical development of the student and an environment for his training, it is a primordial necessity for coexistence in society. Growing up, the child advances in communication skills, the contexts becoming more and more complex and diverse. By developing communication skills, students acquire a complex symbolic system that they will develop and refine throughout their lives. For students with severe hearing disabilities, the presence of a language that can offer the possibility of interactions with those around them is important for the development of communication.
