PSI Massachusetts Master Electrician, Part 1, Certification Package


The certification exam consists of 80 questions in 240 minutes. The minimum score required to pass is 70%, meaning one must get 56 questions correct in order to pass.

In order to become a Master Electrician, one must pass both parts one and two of the Massachusetts Master Electrician exams.

Examinations are OPEN BOOK, computer generated and two part. Examination scores are stand-alone scores, i.e. each part of the examination is independent and you are required to pass both parts of the examination to obtain licensure. Candidates who fail one part of an examination are only required to retake the part of the examination that they failed unless such examination date has expired, in that case applicants are required to resubmit their application and take each part of the examination

In addition to the number of questions per examination, a small number of five to ten “experimental” questions may be administered to candidates during the examinations. These questions will not be scored and the time taken to answer them will not count against examination time. The administration of such non-scored experimental questions is an essential step in developing future licensing examinations.

All the reference materials listed below were used to prepare the questions for this examination. The examination may also contain questions based on trade knowledge, or general industry practices. Except for Codebooks, you can use later editions of references as they become available. For Code questions, the examination will be based only on the edition of the Codebook that is listed.

NOTE 1: New exam items may be added to the examinations, to reflect the adoption of a current Code, or adoption of other related Regulations or laws seven months from the enforcing date of such Code, Regulation or Law.

NOTE 2: Examinations will be based upon the then in effect edition of the National Electrical Code, Massachusetts Electrical Code Amendment, standards and NFPA documents after July 1, of that year.
