The purpose of this study was to investigate the impact of a required assessment course on the assessment literacy of teacher candidates. The findings showed that certain aspects of assessment literacy were present before the course. At the onset of the course, teacher candidates had the highest mean scores for Ethical Assessment, Scoring, and Choosing Assessment Methods. However, the exposure to the course potentially increased assessment literacy in some areas. For instance, the participants came into the course with low mean scores in sound design of assessments and communicating results. The results revealed that the participants increased in their mean scores for sound design of assessment and communicating results on the posttest, though these were still the lowest scores.
