Reflecting the internationalization of the field of second language writing, this book focuses on political aspects and pedagogical issues of writing instruction and testing in a global context. High-stakes assessment impacts the lives of second language (L2) writers and their teachers around the world, be it the College English Test in China, Common Core aligned assessments in the U.S., English proficiency tests in Poland, or the material conditions (such as access to technology, training, and other resources) affecting a classroom. With contributions from authors working in 10 different countries in a variety of institutional contexts, the chapters examine the uses and abuses of various writing-related assessments, and the policies that determine their form and use. Representing a diverse range of contexts, methods, and disciplines, the authors jointly call for more equitable testing systems that consider the socioeconomic, psychometric, affective, institutional, and needs of all students who strive to gain access to education and employment opportunities related to English language proficiency.
