ABSTRACT Hearing loss, which is one of the most common congenital health problems in children, affects approximately 3 of every 1000 newborns in the world. The first three years of life are critical for the development of language and speech skills. Therefore, early diagnosis and early intervention are extremely important for normal language and speech development, especially in young children. The critical age for early diagnosis and early intervention is 6 months and earlier. Speech, language, communication and academic skills of babies with congenital hearing loss who are diagnosed and started education before 6 months of age increase rapidly and become better than their peers with hearing loss around the age of 3 years. Although the results of the research conducted in our country show that there are important developments in early diagnosis and early intervention in our country, it is seen that we have not yet reached the ideal amplification and educational age emphasized by the Joint Committee on Infant Hearing.
