The goal of this book is to emphasize the formal statistical
features of the practice of equating, linking, and scaling. The
book encourages the view and discusses the quality of the equating
results from the statistical perspective (new models, robustness,
fit, testing hypotheses, statistical monitoring) as opposed to
placing the focus on the policy and the implications, which
although very important, represent a different side of the equating
practice. The book contributes to establishing "equating" as a
theoretical field, a view that has not been offered often before.
The tradition in the practice of equating has been to present the
knowledge and skills needed as a craft, which implies that only
with years of experience under the guidance of a knowledgeable
practitioner could one acquire the required skills. This book
challenges this view by indicating how a good equating framework, a
sound understanding of the assumptions that underlie the
psychometric models, and the use of statistical tests and
statistical process control tools can help the practitioner
navigate the difficult decisions in choosing the final equating
function. This book provides a valuable reference for several
groups: (a) statisticians and psychometricians interested in the
theory behind equating methods, in the use of model-based
statistical methods for data smoothing, and in the evaluation of
the equating results in applied work; (b) practitioners who need to
equate tests, including those with these responsibilities in
testing companies, state testing agencies, and school districts;
and (c) instructors in psychometric, measurement, and psychology
programs.
