This book provides an introduction to test equating, scaling and
linking, including those concepts and practical issues that are
critical for developers and all other testing professionals. In
addition to statistical procedures, successful equating, scaling
and linking involves many aspects of testing, including procedures
to develop tests, to administer and score tests and to interpret
scores earned on tests. Test equating methods are used with many
standardized tests in education and psychology to ensure that
scores from multiple test forms can be used interchangeably. Test
scaling is the process of developing score scales that are used
when scores on standardized tests are reported. In test linking,
scores from two or more tests are related to one another. Linking
has received much recent attention, due largely to investigations
of linking similarly named tests from different test publishers or
tests constructed for different purposes. In recent years,
researchers from the education, psychology and statistics
communities have contributed to the rapidly growing statistical and
psychometric methodologies used in test equating, scaling and
linking. In addition to the literature covered in previous
editions, this new edition presents coverage of significant recent
research. In order to assist researchers, advanced graduate
students and testing professionals, examples are used frequently
and conceptual issues are stressed. New material includes model
determination in log-linear smoothing, in-depth presentation of
chained linear and equipercentile equating, equating criteria, test
scoring and a new section on scores for mixed-format tests. In the
third edition, each chapter contains a reference list, rather than
having a single reference list at the end of the volume The themes
of the third edition include: * the purposes of equating, scaling
and linking and their practical context * data collection designs *
statistical methodology * designing reasonable and useful equating,
scaling, and linking studies * importance of test development and
quality control processes to equating * equating error, and the
underlying statistical assumptions for equating
