This research explores how Internet-based video-conferencing technology can be used to deliver and conduct a speaking test, and what similarities and differences can be discerned between the standard and computer-mediated face-to-face modes. The context of the study is a high-stakes speaking test, and the motivation for the research is the need for test providers to keep under constant review the extent to which their tests are accessible and fair to a wide constituency of test takers. The study examines test-takers' scores and linguistic output, and examiners' test administration and rating behaviors across the two modes. A convergent parallel mixed-methods research design was used, analyzing test-takers' scores and language functions elicited, examiners' written comments, feedback questionnaires and verbal reports, as well as observation notes taken by researchers. While the two delivery modes generated similar test score outcomes, some differences were observed in test-takers' functional output and the behavior of examiners who served as both raters and interlocutors.
