On High-Range Test Construction Now

“On High-Range Test Construction Now” demystifies the craft of designing, validating, and responsibly deploying high-ceiling assessments. Moving beyond folklore and forum lore, it unites classical test theory with modern methods—item response theory, Bayesian estimation, and adaptive delivery—to show exactly how to push ceilings higher without sacrificing rigor. Inside, you will find: principled approaches to item writing for extreme difficulty; strategies for small-sample norming and error bounds; safeguards against coaching and leakage; fairness checks and differential item functioning analyses; replication protocols; and practical workflows for remote administration. Clear case studies, templates, and decision checklists walk you from concept to pilot to publication, with transparency and ethics at the center. Whether you are a psychometrician, a researcher exploring outlier performance, or a community builder seeking credible measures, this book offers the tools—and the discipline—to separate signal from noise at the far right tail. Thoughtful, precise, and actionable, it is the definitive guide for anyone determined to create high-range tests that stand up to scientific scrutiny and real-world use.
