With the growing need to nurture students’ independent learning, English language teaching (ELT) practices should reflect student-centered assessment approaches, such as self-assessment, an ultimate goal of higher education. It has been pointed out that to conduct effective self-assessment, students need to be taught systematically, and that is where teachers are expected to step in. Prior to implementing such a change in ELT, it is important to conduct research on English as a foreign language (EFL) teachers’ attitudes toward, and self-efficacy beliefs about, implementing self-assessment to cultivate capable student self-assessors. Although the strong global endorsement of self-assessment over the past two decades has witnessed its classroom implementation in different disciplines, such studies are scant in relation to EFL writing classrooms. To address this gap, the present qualitative research examined five Chinese tertiary EFL writing teachers’ attitudes toward and self-efficacy beliefs about student self-assessment of writing, as well as possible reasons that discourage them from engaging students in self-assessment practices. Data collected from in-depth, semi-structured interviews indicated that self-assessment, a critical element of self-regulated learning, is surprisingly missing from the teachers’ knowledge base and previous practices. Additionally, the findings offer insights into the striking differences in teachers’ understanding of, attitudes toward, and low self-efficacy beliefs about self-assessment of writing. Reasons why teachers choose not to implement self-assessment of writing are also discussed. Findings from this study contribute to a deeper understanding of how EFL teachers’ attitudes and self-efficacy beliefs are enacted in relation to their classroom assessment practices in order to move forward discussions on the feasibility of implementing self-assessment of writing in tertiary EFL classrooms.

Although the benefits of using self-assessment on student writing performance have received wide recognition over the past two decades, minimal research is available on the effects of using self-assessment of writing on English as a foreign language (EFL) students’ writing performance, especially in the tertiary context of China, where such research is still in its infancy. To fill the abovementioned lacuna, the present study adopted a quasi-experimental approach to implementing a self-assessment-based intervention in Chinese tertiary EFL writing classes. Specifically, students were randomly assigned into either an intervention class that implemented self-assessment or a comparison class that employed peer assessment as classroom practice to promote students’ sustainable development of writing skills. Quantitative and qualitative data were collected, and the research findings indicated that the intervention group experienced a larger increase in their holistic writing performance and rating accuracy when compared with the comparison group. Furthermore, the qualitative findings reveal students’ enhanced rating accuracy after the intervention. This study contributes to research on self-assessment in the EFL writing domain as a basis for further deliberation on self-assessment in higher education, and it also provides much needed empirical evidence for the potential value of student-centred sustainable assessment approaches such as self-assessment. Findings also provide teachers with pedagogical implications for developing sustainable and capable self-assessors of writing.
