My research investigates the relationship of assessment qualities and purposes on student and teacher responses to assessment including learning outcomes across a variety of cultural and social contexts. My research brings the concerns and skills of psychometrics to bear on the social psychological factors of assessment. My research has shown that teacher and student beliefs are (1) contingent on assessment quality, (2) consistent with cultural values and priorities, and (3) play a significant part in explaining adaptive and maladaptive outcomes. Further, my research has shown that improvement is best achieved through high-quality assessment practices and systems that provide rich feedback to both test-users and test-takers and that this outcome is contingent on ensuring low-stakes consequences are attached to assessments.
