The bulk of this guide is devoted to the detailed description of 18 tests of English as a second language (ESL). Most of the tests were produced in Great Britain, the remainder in the United States. Each description provides information on the source, aims, and administration of the test; outlines the content of the test; and, where pertinent, indicates the recognition that will be earned through certification in ESL on the basis of the test. To supplement the descriptions, the volume offers an analysis of contents and techniques in ESL testing, definitions of terms used in standardized testing, a note on Cloze procedure, and a ten-page bibliography.
