Mastery-grading techniques such as mastery-based grading, specifications grading, and standards-based grading are assessment techniques professors are implementing in order to support a growth mindset of learning, decrease test anxiety, and help students develop a deeper understanding of course objectives. In this paper, we provide an analysis of research conducted in a variety of courses which used mastery-based testing (MBT). Some of the questions we explore include whether the students' attitudes about mathematics and learning changed throughout the course in addition to whether MBT impacted test anxiety and growth mindset.
