The research on the second language (L2) speaking assessment has been predominantly concerned with formal proficiency tests. However, with a growing interest in learning-oriented assessment (LOA), more researchers are interested in learner involvement in speaking assessment (Blanche Luoma, 2004; Ocarson, 1989). Self- and peer-assessment of speaking, where learners evaluate the performance of their own and their peers, can be an exemplar of assessment with its primary purpose on learning (Chen, 2006, 2008; Ibersson, 2012; Saito, 2008; Topping Chen, 2008, Rivers, 2001).
