This volume contains a selection of research papers that were presented
at the 15th Annual Language Testing Research Colloquium (LTRC) on the
themes of performance testing, and on aspects of communication in
relation to cognition and assessment. This edited collection includes
contributions reporting research into the testing of speaking and
writing, especially in relation to raters, tasks and assessment
criteria, contributions exploring the application of various statistical
methods in langauge test validation and contributions addressing the
issues relating to langauge testing in specific contexts with particular
candidate groups. This volume will be of relevance to language testing
specialists concerned with the design, development, delivery and
validation of performance tests, as well as to academic researchers and
graduate students interested in the complex relationship between
cognition and assessment.
