Lecturers, request your electronic inspection copy to review it for
your course. Validity is the hallmark of quality for educational
and psychological measurement. But what does quality mean in this
context? And to what, exactly, does the concept of validity apply?
These apparently innocuous questions parachute the unwary inquirer
into a minefield of tricky ideas. This book guides you through this
minefield, investigating how the concept of validity has evolved
from the nineteenth century to the present day.
Communicating complicated concepts straightforwardly, the
authors answer questions like: What does 'validity' mean? What does
it mean to 'validate'? How many different kinds of validity are
there? When does validation begin and end? Is reliability a part of
validity, or distinct from it?
This book will be of interest to anyone with a professional or
academic interest in evaluating the quality of educational or
psychological assessments, measurements and diagnoses.
