Language varieties are found in all languages and may be the result of geographical, temporal, social, or situational factors. Research on language attitudes has shown that speakers often have negative attitudes towards non standard varieties and develop prejudice against speakers of such varieties. This research aims to provide insight into the attitudes of speech and language pathologists (SLPs) towards non standard language varieties. A total of 122 S LPs from the Republic of Croatia filled out an online questionnaire comprising 28 statements regarding attitudes towards non standard varieties. The participants specified their levels of agreement with the statements on a Likert scale. The results showed that SLPs maintain mostly neutral to positive attitudes towards non standard varieties in general, but display negative attitudes towards the use of non standard varieties in the educational context. It was found that there is no connection between the per sonal and professional experiences of speech therapists and their attitudes, apart from the variable of years of work experience, whereby more experienced or older SLPs adopt more negative attitudes towards non standard varieties. The research also showed that SLPs employed in the educational sector cultivate more negative attitudes than SLPs working in other sectors. Such attitudes can negatively impact the provision of speech therapy services to speakers of minority linguistic and cultural backgrounds. Th e results of this research point to the need for defining a framework of speech therapy work with clients with minority linguistic and cultural status and improving SLPs’ knowledge of non standard varieties.
