Editor's note
As Stephen Stoynoff points out in his state-of-the-art review of four major international ESOL examinations, more than 500,000 examinees take each of these tests annually, making them among the most widely used ESOL examinations in the world. The inferences and decisions made with the scores from these tests have significant consequences for examinees, score users, and society. Thus, his review will contribute to the professional discourse in several ways: by providing a context for discussing some of the fundamental considerations and persistent issues in language assessment, by demonstrating how language testing research and concerns for test consequences are affecting the test design and validation activities related to these four extremely influential assessments of L2 ability, and above all by encouraging a thorough consideration of important aspects of these high-stakes assessments. The paper is accompanied by a comparative review of books by Christine Coombe.
