Master Installer Series
This series of tests consists of two exams to reach the level of Journeyman Installer (JI); two additional exams to reach Master Installer certification (MI); and one additional exam to become certified as a Master Installer/Designer (MID). The exams have a 2 hour time limit with the exception of Master Installer 1 and Master Installer 2 and Master Installer/Designer. For those exams, there is a 2 ½ hour time limit.
Exams are given once yearly at our spring Annual Conference. However, an applicant wanting to sit for the exam at alternate times or sites may arrange for the LPI to work through a proctor. The applicant is responsible for finding a proctor (we suggest contacting a local library or college, who often have persons that proctor tests) and making all arrangements with the proctor. A proctor cannot be employed by the applicant’s business or be related to the applicant. Any charges for proctor services are the responsibility of the applicant, and no billing will be handled by the LPI for these services.
The LPI will mail exam(s) marked for the applicant to the proctor. After the proctor oversees the test taking, (s)he will return the completed exam(s) to the LPI with a notice certifying his/her monitoring of the examination process. The LPI office will score the exam(s) and notify the applicant of the results in writing.
The fee for each exam is $100 for persons employed by LPI member companies and $200 for non-members, payable prior to the exams being sent to a proctor. *There is a 50% discounted rate on each test if taken at our LPI/ULPA Annual Conference (please mark on your application the Proctor is “Annual Conference” so we can distinguish your application). The exams require 70 percent or more correct for passing. Examinations that are not passed may be retaken at any time by following the above procedures and submitting new payment (it is not free to retest, the fee applies each time you test irregardless of how many attempts have been made). An individual may take all 5 tests in one sitting, however, the tests must be passed sequentially before certification is to be issued.
Each Journeyman Installer, Master Installer and Master Installer/Designer will be billed a $50 re-certification fee due on June 30th of each year. An update test will also be required when lightning protection standards change. (Journeyman Installers whose companies are not members of LPI must pay an additional $450 in annual dues; Master Installers and Master Installer/Designers whose companies are not members of LPI must pay an additional $700 in annual dues.)
Study materials for the exams are available for sale through the online store. Copies of the NFPA-780 Standard sell for $65.50 each. Copies of the LPI-175 Standard range from $40.00-$55.00 (download or hard copy options available). Hard copy prices include all shipping and handling.
The Journeyman Installer, Master Installer and Master Installer Designer tests include true/false, multiple choice, short answer and/or fill in the blank questions as well as design application problems. More design problems are included with each progressive test. A thorough knowledge of NPFA-780 and LPI-175, including formulas, material sizes and design parameters will be tested along with the ability to apply requirements to paper design drawings.
