Although second language learners' pragmatic competence (their ability to use language in context) is an essential part of their general communicative competence, it has not been a part of second language tests. This book helps fill this gap by describing the development and validation of a web-based test of ESL pragmalinguistics. The instrument assesses learners' knowledge of routine formulae, speech acts, and implicature in 36 multiple-choice and brief-response items. The test's quantitative and qualitative validation with 300 learners showed high reliability and provided strong evidence of the instrument's construct validity. Its web-based format makes it easy to administer and score. The book ends with a discussion of future research directions in assessing second language pragmatics. Contents: Interlanguage pragmatics - Second language assessment and web-based testing - Assessment of second language pragmatics - Quantitative validation of a test of ESL pragmatics: group comparisons, correlational techniques, IRT - Qualitative validation with verbal protocols - Threats to construct validity - Future research in testing L2 pragmatic competence.
