The training of teachers is one of the most critical factors in improving the quality of teaching and assessment in the classroom. EFL teachers need to be literate in language assessment; this can be achieved through training. A total of 147 Junior High School EFL teachers was surveyed to identify their training needs in assessmen. Semi-structured interviews with 10 randomly selected teachers were also conducted, and analysed using thematic analysis. The study identified three competencies that teachers expected to gain from assessment literacy training: the ability to select tests for use, ability to develop tests' specification, and ability to develop test tasks and items. More importantly, the study results suggest that teachers need ongoing practical training in a range of topics with different priorities. These findings offer guidance for planning effective teacher training and the design of modules based on teachers' needs.
