As the number of children with communication disorders (autism spectrum disorder and social communication disorders) increases, so does the number of children with communication disorders involved in speech-language pathology support. Therefore, an analysis of speech-language pathologists practice in Croatia is important in order to gain insight into the most common challenges and problems that they face. For this purpose, an online questionnaire on speech-language pathology practice in Croatia in the context of communication disorders was designed. The study involved 63 speech-language pathologists employed in preschool, primary or secondary school, the health care system, social welfare system and private practice. The results show that most speech-language pathologists include children with communication disorders in their support. The most common reason for non-involvement is insufficient knowledge or experience. Also, too many administrative tasks and other obligations that are not closely related to the field of speech-language pathology as well as a large number of children who need speech-language pathologists support are the reason for less frequent inclusion of children with communication disorders. Most speech-language pathologists use established and emerging interventions to improve communication and language comprehension and production. Also, most speech-language pathologists use high and low technology aids only occasionally. Speech-language pathologists most often work with parents, and least often with preschool and school teachers. In achieving better partnership with other experts, they are usually hindered by work overload and the lack of agreed and mandatory collaboration between experts and institutions, which is why the current collaboration is based largely on mutual acquaintances and personal initiative. Also, speech-language pathologists with less years of work experience feel more competent to work with children with communication disorders and have better knowledge about the characteristics of communication disorders. The results obtained by this research provide insight into the needs related to the improvement of speech-language pathologists practice in Croatia and encourage the solution of the most common challenges that speech-language pathologists face when providing support for children with communication disorders.
