This publication was the blueprint foundation for all of the definitions and concepts used to perform the job analyses that were collected to construct the DOT. To understand what Worker Characteristics really mean, study the related chapters in this book. This is what job analysts used when they observed an occupation being performed. When they were uncertain how to classify a variable, they studied the examples in this book to make the best rating that they could. Complete reprints of this critical resource book are available at Elliott & Fitzpatrick. SkillTRAN has scanned the entire book and is presenting the information chapter by chapter. Each chapter includes a table of contents for the entire book. The Introduction page to the RHAJ clearly states that the methodology described in the RHAJ was the methodology used to gather and record information about jobs for the DOT, the Selected Characteristics of Occupations (SCO) and the Guide for Occupational Exploration (GOE).
