3.1 This guide defines the use and content of Position Task Books.3.2 A Position Task Book lists all of the observable activities which must be performed to demonstrate the ability to successfully fill a position or operational level.3.2.1 Each activity, or Task, partly or fully demonstrates the existence in an individual of a specific Behavior.3.2.2 One or more of these Behaviors signifies that the individual is capable of a particular Competency.3.2.3 One or more defined Competencies are required for each position or operational level.3.3 Each Position Task Book used to document the suitability of an individual to perform in a particular position or operational level shall meet the requirements of this guide.3.4 Nothing in this guide precludes an authority having jurisdiction (AHJ) from adding additional content to a Position Task Book.3.5 This document may be used by an AHJ to develop Position Task Books.1.1 This guide defines the use and content of Position Task Books in a “competency-based qualification system.”1.2 Each Position Task Book lists the competencies, behaviors, and tasks required for successful performance in a position or operational level.1.3 Position Task Books provide a standard form for documenting the knowledge, skills, and abilities of an individual by observation of that individual’s performance of tasks in a position or at a particular operational level. When all tasks in the PTB are successfully completed, the evaluated individual is considered qualified and eligible for assignment in that position or at that operational level.1.4 This guide only defines the use of Position Tasks Books and the content required for successful application. It does not define the requirements for any position or operational level.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
