Mastery-based contract grading is a holistic assessment approach for learning and grading in which students choose their desired effort and outcome by contracting for either an A or B to meet high academic standards. This mixed-methods study examined the impact of mastery-based contract grading on secondary students’ (grades 9–12) perceptions of stress and threat appraisal. Participants were 439 adolescents, including 284 returning students and 155 first-year students, completing a high-stakes writing assessment in their required English course. Using an explanatory sequential design, interviews with 40 adolescents from all grade levels and course types explained the findings of matched-pairs quantitative data generated from four psychometrically sound scales. The findings revealed that the contract significantly reduced evaluative threat by clarifying expectations and bolstering confidence. Consequently, compared to their prior experience with or expectations for the task, adolescents perceived workload demands as significantly less stressful and threatening under the contract. The findings of this study make a significant contribution to the field of writing assessment, leading to a call to action for teachers to implement mastery-based contract grading in high school classrooms to create psycho-emotionally healthy learning environments that reduce perceptions of stress and increase challenge appraisal. © 2021 Elsevier Inc.
