Examination Content: Portable Power Distribrution Technican

To begin your preparation for the Portable Power Distribution Certification Examination, you need to know what content areas are included in the actual examination. Information regarding the content of the examination is presented below and in the Candidate Handbook.

The content outlines provide a general overview of the examination and can give you specific study direction by revealing the relative importance of each category on the examination. The content for the examination is based on a job analysis performed by twelve subject matter experts under the guidance of a professional psychometric firm, along with input from hundreds of electricians across North America.

To determine whether the Entertainment Electrician Certification or the Portable Power Distribution Technician Certification is right for you, please read the Scope of Work Document.
