The editors and authors in this edited collection, available in two volumes, consider the increasing importance of students' and teachers' lived experiences within the development and use of writing assessments. Presenting key work published in The Journal of Writing Assessment since its founding in 2003, the collection explores five major themes: technical psychometric issues; politics and public policies shaping large scale writing assessments; automated scoring of writing; fairness; and the lived experiences of humans involved in assessment ecologies. The books also provide reflections from leading writing assessment scholars who examine how these themes continue to shape current and future directions in writing assessment.
