“Scale Development is readable, concise, and affordable. Students like the book. It presents formulas but doesn’t emphasize them but rather emphasizes utility, and the book is well-suited for an audience with applied interests.” (Kathy E. Green)
"The key strength of this text is its ability to present the basic and necessary background on scale construction and measurement for the subsequent material, either in the context of the same first-year graduate course or in future courses during a masters and PhD program.” (René Bautista)
“The author has a very nice writing style that makes reasonably complicated technical concepts clear to students who are accessing them for the first time.” (Catherine Horn)
“This book does an excellent job in explaining complicated topics in test construction at a level that students can understand. The use of specific examples that demonstrate key points is very effective.” (Jonathan Feldman)
