The paper proposes the preparation of a new generation of assessment literate teachers. The issues of student assessment literacy and, more specifically, prospective language teacher assessment literacy have not been sufficiently investigated as of yet, although research into the topic seems to have gained momentum. Recent studies state that the assessment literacy of teachers is essentially affected by their pre-existing conceptions of assessments), and teacher education should integrate shaping such conceptions into courses; the process of shaping conceptions is quite long and, because it is time-consuming, it may deter assessment literacy building. The current study explores the conceptions of the assessments shaped by prospective teachers within a general English course. The two major conceptions of assessment, relevant for the framework of teaching general English to second-year student teachers of English, are the understanding of feedback and knowledge of assessment construct and criteria. The findings of the study in this cohort of students of the particular course in language assessment shows that the students’ progress was considerably higher than that of a comparison group in the previous 2020 study. The author suggests two types of AL, i.e., student and prospective teacher assessment literacy.
