The twofold objective of this book is to enable the teacher of English to speakers of other languages both to improve his own classroom measures and to make sound assessments of standardized tests which he may from time to time be asked to select, administer, and interpret. Chapters 1 and 2 introduce the general purposes and methods of language testing and consider the chief characteristics of good educational measures. Chapters 3-8 describe specific techniques for testing grammatical structure, auditory discrimination and comprehension, vocabulary, reading comprehension, writing, and oral production. Constructing and administering the test and interpreting and using test results are described in Chapters 9-11. Chapter 12 offers procedures for calculating a few basic test statistics which will aid the teacher/test-writer in evaluating the soundness of his tests and the performance of his students. Neither the final chapter nor the preceding chapters assume previous training in tests and measurement or knowledge of advanced mathematics. A list of selected references and a subject and author index conclude the volume. (AMM)
