The comparability of measurements made in differing circumstances by
different methods and investigators is a fundamental pre-condition for
all of science. Successful applications of technology require comparable
measurements. While the applications here focus on educational tests,
score linking issues are directly applicable to medicine and many
branches of behavioral science. In this book, experts in statistics and
psychometrics describe classes of linkages, the history of score
linkings, data collection designs, and methods used to achieve sound
score linkages. They describe and critically discuss applications to a
variety of domains. They define what linking is, to distinguish among
the varieties of linking and to describe different procedure for
linking. Furthermore, they convey the complexity and diversity of
linking by covering different areas of linking and providing diverse
perspectives.
