A free online book about psychometric tools for psychological assessment

An introduction to tests and measurements

Renée Tobin and I helped update Ronald Cohen’s Psychological Testing and Assessment: An Introduction to Tests and Measurements. It is a comprehensive textbook suitable for introductory psychological assessment courses.
