“…As has been noted by Malone and Montee (2010), though OPIs are implemented by trained and certified testers, "…human error is inevitable and can be limited but not eliminated" (p. 978). In this regard, pairing or even grouping the test-takers and asking them to interact with each other may help remedy this weakness (Brooks, 2009;Brown & Abeywickrama, 2018;Green, 2021;Hırçın Çoban, 2017;Jankowska & Zielińska, 2015;Louma, 2004;Prasetyo, 2018;Sandlund et al, 2016) because, as has been reported by Ahmadi and Sadeghi (2016) and Brooks (2009), positive washback, more natural discourse and more various language functions can be attained and the workload of the rater in terms of time, effort and cost may be reduced. Moreover, when test-takers are paired or grouped, they tend to feel less anxious in comparison to the traditional OPI (Hırçın Çoban, 2017).…”
