This article is based on an experiment designed to conduct an interpreting test for multiple candidates online, using web-based synchronous cyber classrooms. The test model was based on the accreditation test for Professional Interpreters produced by the National Accreditation Authority of Translators and Interpreters (NAATI) in Australia. Specifically, the test involved interpreting-specific components such as dialogue interpreting, sight translation, and consecutive interpreting, as well as non-interpreting-specific components such as questions on ethical issues. The test was conducted live synchronously and concurrently with multiple candidates--i.e., all candidates were tested in their own locations at the same time. The result of the experiment indicates the potential and feasibility of conducting interpreting tests online using the specific technology of synchronous cyber classrooms. However, there are also a number of constraints when compared to conventional face-to-face tests. There is a need for further studies on how to effectively apply this kind of technology to conduct interpreting tests for multiple candidates online in synchronous mode and without the constraints identified in this research.
