Validation in language testing

the long version

"The validation of language tests is widely discussed and expected, but only in recent years have researchers adopted a variety of innovative techniques for developing, assessing and validating specific tests of second or foreign language proficiency and their impact on education and society. Indeed, as the present volume clearly demonstrates, many different techniques for empirical analysis and types of evidence may be used to assess and interpret the validity of diverse aspects of language tests as well as the consequences they may have for language students, educators and society."--Jacket.
