Important Notes:

  • Refer to your candidate information bulletin provided by PSI for a complete list of which reference books can be taken into your exam.
  • Candidates are responsible for bringing their own references to the examination center. Reference materials may be highlighted, underlined and/or indexed prior to the examination session. (Permanent tabs and highlighting is permitted. No notes !!!)

The trend has been over the last 5-10 years for the state examinations to be developed out of the code books that the State and the inspectors have adopted, rather than base questions on practical or hands-on experience. This is the main reason that our software program is so vital to your exam preparation. The majority of our customers are experts when it comes to installation and service for their specific trade, but are not proficient with timed computer examinations that are based on text and code book topics. Since we know that you are going to have to answer questions from specific code book sections, we focus our effort to develop exam prep materials for those sections.This allows you to focus your time and effort on these topics, and not misuse your time simply reading through the code book.
