This edited collection provides the first principled examination of social justice and the advancement of opportunity as the aim and consequence of writing assessment. Contributors to the volume offer interventions in historiographic studies, justice-focused applications in admission and placement assessment, innovative frameworks for outcomes design, and new directions for teacher research and professional development.

The volume concludes with 18 assertions on writing assessment designed to guide future research in the field. Written with the intention of making a restorative milestone in the history of writing assessment, Writing Assessment, Social Justice, and the Advancement of Opportunity generates new directions for the field of writing studies. This volume will be of interest to all stakeholders interested in the assessment of written communication and the role of literacy in society, including advisory boards, administrators, faculty, professional organizations, students, and the public.
