The current study is conducted with the aim to explore the practices and perceptions of Afghan EFL lecturers toward assessment. A second aim of the study is to explore the challenges the lecturers encounter in the implementation of formative assessments in their classes. To serve these basic objectives, a qualitative case study method design was employed with three English language lectures as the participants. Semi-structured interviews were used as the main instrument to collect data. The findings of the study indicated (...) that all three lecturers maintained positive perceptions toward formative assessment and favored it over summative assessment. However, the study also discovered that the lecturers practice summative assessments more than formative assessments in their classrooms. This, as indicated by the lecturers, was due to the fact that their choices of employing certain assessment practices were dictated in terms of certain challenges such as university rules and policies, large classes, and time constraints. Lastly, some suggestions are made that may prove useful to effectively apply formative assessment in Afghan EFL context. (shrink)
