Arrive early, with one ID
Get there at least 30 minutes before your appointment; arriving late can cost you the exam fee. Bring one valid, unexpired, government-issued photo ID with your signature, such as a driver's license, state ID, passport or passport card, military ID, or green card. The name must match your PSI registration exactly.
Two parts, two sets of books
| Part 1 | Part II, Business and Law | |
|---|---|---|
| Questions | 90 | 50 |
| Time | 240 minutes | 120 minutes |
| Pass | 70% | 70% |
| References in the room | NEC, NFPA 72, 527 CMR 12.00 | NASCLA guide, 237 CMR, M.G.L. c. 141, 143, 151, 152 and 254 (listed sections), the state unemployment guide, OSHA 29 CFR 1926 |
Bring the right books for the part you're taking. The bulletin lets the code and law references be paperback, ring-binder, spiral or loose-leaf, tabbed or untabbed, with highlighting and underlining. You may also bring the business references the bulletin lists, such as OSHA standards and the wage, lien, workers' compensation and unemployment publications, marked up the same way.
Notes, formulas and calculators
- Formulas may be written on the blank pages of your code book before the exam.
- Handwritten notes are allowed in the margins of the allowed references.
- During the exam, you may write only on PSI's scrap paper.
- Calculators must be silent, battery-operated, non-programmable, non-printing, and have no alphabet keys.
Loose papers that aren't part of a bound book, binder or multi-page CMR, MGL or NFPA document must stay outside.
Rules in the room
No electronic devices except hearing aids. No food, drink or smoking. Copying or sharing exam content disqualifies you and can lead to legal action.
Pacing
Part 1 gives you 240 minutes for 90 questions, about 2 minutes 40 seconds each. Part II gives you 120 minutes for 50, about 2 minutes 24 seconds each. Most lost time comes from long lookups, so answer what you know on the first pass and come back for the rest. On Part II, tabbing 237 CMR and M.G.L. c. 141 pays off: 16 questions come from them.
Scoring and retakes
Each part is scored on its own, and you need 70% on both. If you fail one part, you retake only that part within 12 months of your approval date, and you must wait at least 24 hours to retest.
Canceling or rescheduling
Cancel at least two days before your exam (a Monday exam must be canceled by the Saturday before), online or by speaking to a PSI representative; a voicemail doesn't count. A missed appointment, a late cancellation, arriving after the start, or the wrong ID forfeits the fee. If bad weather closes a center, PSI reschedules at no charge.
