Research consistently shows that solid assessment designs lead to better student learning outcomes. The development of well-designed assessments presents a challenge to preservice teachers in their attempts to master the process and to the teacher educators who instruct them. This exploratory study examined strategies for teaching assessment design utilized by 87 teacher educators in the United States. Analysis of the results showed that expository, collaborative, and hands-on approaches were used, with assessment approaches aligning to structured or unstructured approaches. Data also revealed that the participants tended to focus more on the vocabulary related to assessments rather than the strategies for design.
