A conceptual introduction to psychometrics | Maatwerkeditie

Design better tests – and defend them with evidence. A Conceptual Introduction to Psychometrics guides students and practitioners through the full cycle of psychological and educational measurement, connecting day-to-day test construction with the theory that underpins valid decisions.

What you’ll gain:

• A clear roadmap for developing maximum performance (ability, achievement) and typical performance (personality, attitudes) tests: from construct definition to item formats, administration, and piloting.
• Practical, research-ready item writing and rating guidelines that improve clarity, fairness, and reliability.
• An accessible entry into Classical Test Theory (reliability, SEM, difficulty, discrimination, distractors) and Item Response Theory (Rasch and logistic models, dimensionality, information, invariance).
• A balanced view of validation as an evidence program: content, process, experimental and correlational studies.
• Transfer to practice: norming and score interpretation, prediction and selection, person-fit, optimal test design, and computerized adaptive testing—plus ethics, fairness, and test-taker rights.

Why choose this book:

• Concept first, math-light: only an introductory statistics course required.
• Teach it your way: suitable for a one-semester CTT course, a one-semester IRT course, or a two-semester sequence covering development, analysis, and applications.
• Learn by doing: worked examples, real datasets, and end-of-chapter exercises.
