ICC CA Exam Day: Four Books, Two Minutes a Question

Sixty questions in two hours sounds comfortable until you count the books. The CA tests four separate documents, and the cost of opening the wrong one is most of your two-minute budget for that question.

Knowing which book answers which question is the skill this exam actually measures.

The format

Questions	60
Time	2 hours
Per question	2 minutes
Book policy	Open — you bring your own references
Pass mark	75%
Delivery	ICC PRONTO remote proctoring, or a Pearson VUE test centre

Two minutes is a middling budget for this family — more generous than FE's 72 seconds, far tighter than F3's three and a half minutes. It supports roughly one real lookup per question if you go straight to the right book.

Which book answers what

This is the mapping worth memorising before you memorise anything else:

If the question is about…	Open
Appliance spacing, candela, audibility	NFPA 72 Ch. 18
Detector spacing, manual stations	NFPA 72 Ch. 17
Panels, off-premises communication	NFPA 72 Ch. 10 and 24
Elevator recall, HVAC shutdown, door release	NFPA 72 Ch. 21
ITM frequencies and methods	NFPA 72 Ch. 14
Record of completion, documentation	NFPA 72 Ch. 7
Circuit classes, survivability, pathways	NFPA 72 Ch. 12
Conductor sizing, power limits, wiring methods	NEC Art. 760
Where a system is required at all	IFC / IBC
Permits, approvals, administration	IFC Ch. 1

Most of the paper lives in NFPA 72. The NEC appears for wiring specifics and the I-codes appear for whether a system is required and for administration. Reaching for the IFC on a spacing question is a wasted minute.

The edition mismatch

CA tests these editions:

Reference	Edition
NFPA 72	2019
National Electrical Code	2020
International Fire Code	2021
International Building Code	2021

If you own a 2022 NFPA 72 — many working technicians do — the chapter structure is close but section numbers have moved. You will look up what you are sure is the right section and read something adjacent.

Confirm the current edition list on the CA page in the ICC Exam Catalog. ICC revises it on its own schedule, and the catalog is the only authoritative source.

What you may carry in

• References must be bound — original bound book, three-ring binder, or stapled.
• No photocopies of copyrighted material. Candidates are turned away for this.
• Permanently attached tabs are allowed — ones that cannot be removed without damaging the page.
• Pre-existing highlighting and ink notes are fine.
• You may not write in your references during the exam. Scratch paper or an on-screen notepad is provided.

Annotations made before exam day are permitted; annotations made during the exam are not.

Tab for the real weighting

The most common preparation error on CA is tabbing detection heavily and notification lightly. The published weights say the opposite:

Domain	Weight	Tab priority
Notification Appliances	22%	Heaviest — Ch. 18 tables
Initiating Devices	19%	Ch. 17 spacing
Control and Communication	15%	Ch. 10, 24
Ability to Read Plans	13%	—
Functional Control Interfaces	10%	Ch. 21
Inspection and Testing	6%	Ch. 14 tables
Documentation	5%	Ch. 7
Wiring, Circuits and Pathways	5%	NEC 760
General Administration	5%	IFC Ch. 1

Notification is the single largest domain. Tab Chapter 18's appliance tables first.

PRONTO or a test centre

Four books is a real consideration. PRONTO lets you sit at your own desk with your own tabbed set — you need a quiet room, a clear desk, a webcam and a stable connection, and the proctor will ask you to pan the room. Pearson VUE removes the technology risk but means carrying four books and working on unfamiliar desk space.

If you do not pass

Six attempts within a six-month period, paying the fee each time. Use all six and you wait six months from your first attempt.
