This research aims to customize the System Usability Scale (SUS) so it can be used as a standard usability measure on native Arabic-language speakers. A process of rigor translation followed by psychometric evaluation has been administered through a questionnaire in the Arabic-language that reflects a reasonable level of reliability, validity and sensitivity when compared to the original English-language SUS questionnaire. The final result of the Arabic-System Usability Scale (A-SUS) is then applied on students majoring in Communication Disorders Sciences (Kuwait University) to measure the usability of a mobile application. A-SUS encapsulates the essence of the original SUS and provides an adequate tool for professionals to use with Arabic native speaking users to evaluate systems usability.
