Maryland master electrician exam
The Maryland master exam is 90 questions in 4 hours, open book on the 2020 NEC, 70% to pass, and calculation-heavy (calculations are 30 of the 90 questions). It needs 7 years of experience. There is currently no rule that you must hold a journeyperson license first.
What separates the master exam
The master exam adds 20 questions over the journeyperson test and leans hard on calculations. Calculations are 30 of the 90, so service and feeder sizing, dwelling and commercial load, motor circuits, and conduit fill carry the day. Open book does not rescue a wrong setup. You have to know the calculation path cold and use the 2020 NEC to confirm, not to figure it out from scratch under the clock.
If you searched for Maryland master electrician practice test
Do not judge a practice test by question count alone. Maryland master prep has to separate the 90-question master tier from the 70-question journeyperson tier, then put more weight on service, feeder, motor, transformer, fill, and load-calculation setup. The diagnostic is the first filter: if it shows calculation or codebook speed misses, the paid practice path has a clear job.
Eligibility
7 years of experience under a Maryland master (the Board may credit up to 3 years for formal training). There is currently no rule requiring a Journeyperson license first.
The exam format
PSI Services delivers the master exam as a single test: 90 questions in 4 hours, open book on the 2020 NEC, 70% to pass. Maryland law and rule (Business Occupations and Professions Article Title 6, section 6-304, and COMAR 09.09.01) is tested inside the single exam, not as a separate scored section. State code overrides the NEC where they conflict.
Fees
The exam fee is $65 to PSI, and the master license fee is $25.00 once you pass. You pay the exam fee again each time you sit.
If you do not pass
Wait 30 days from your most recent attempt to retest, and pay the $65 exam fee again. Your exam approval is valid for one year. On a calculation-heavy test, the score report usually points at one or two article families. Drill those, not the whole code book. The recovery plan lays out how to use the 30-day window.
Reciprocity
There is currently no Journeyperson reciprocity from other states or Washington DC. An out-of-state journeyperson moving to Maryland must pass the Maryland exam. Master-level reciprocity exists with Virginia, DC, West Virginia, and Delaware.
State license, but check the county
A Maryland state license does not replace local registration. Counties and Baltimore City can no longer issue licenses, but many still require a local registration, permits, and inspections before you can work there.
Renewal and continuing education
Every 2 years. 10 hours per 2-year renewal.
Where do your calculations stand?
Start with the free 15-minute diagnostic. It shows the article families and calculation patterns costing you the most, which matters on the master exam because calculations are 30 of the 90. Then the paid plan drills those weak areas with original questions, calculators, a 30-day plan, and study guides, all on the 2020 NEC.
