The gap between clearing your Internship in Architecture Program hours and sitting your first ExAC is longer than most interns expect. You do not need the full 3,720 hours to register: eligibility is Intern or Candidate status, full CACB certification and a minimum of 2,800 approved hours. What you do need is an eligibility application, a registration window that closes in July for a November sitting, and a study runway. This post maps the six months so you can move through them without missing a deadline.
| Planning window | Work back from the November sitting; registration closes in July |
|---|---|
| Administrative phase | Months 1 to 2: eligibility application and registration |
| Study runway needed | At least 3 months of active study |
| ExAC sittings | Once a year, over two consecutive days in November |
| Eligibility processing | 4 to 8 weeks (varies by province and period) |
| Most common mistake | Waiting for full IAP completion when 2,800 approved hours is the bar |
You are working through the Internship in Architecture Program (IAP) and the ExAC is next. Start here, because the first thing to correct is the assumption that you have to finish the IAP first. You do not: the ExAC asks for Intern or Candidate status, full CACB certification, and a minimum of 2,800 approved experience hours, against the IAP's own 3,720. What you are not sure about is the sequence: when to apply for eligibility, which November to target, and when to actually start opening the books.
This is not a study plan. The 3-month ExAC study plan covers what to read and when. This post covers the months before that plan starts: the eligibility application, the sitting decision, and the preparation work that most candidates do not think about until they are already behind.
If you have already confirmed your eligibility, skip directly to the 3-month study plan. This post is for the candidate still in the gap between hitting 2,800 hours and sitting down to write.
The cards below map the six months from eligibility to exam day, counting back from a November sitting. Months 1 and 2 are administrative and land in the spring, because the registration window closes in July. Month 3 is orientation. Months 4 and 5 are the study sprint. Month 6 is mock exams and review. The study sprint maps directly onto the 3-month ExAC study plan, which breaks those months down to the chapter level.
Month 1
Confirm and submit your IAP.
Verify all your IAP experience hours are recorded correctly in your log and confirm every reported area has a sign-off from a licensed architect. You need at least 2,800 approved hours, or 2,800 hours submitted for approval before the experience submission deadline, not the full 3,720. Submit them to your provincial architectural authority and request written confirmation of receipt.
Do not start heavy studying yet. You do not have a sitting confirmed, and reading-list material studied six months before the exam fades faster than it helps.
Month 2
Apply for eligibility and choose your sitting.
Contact your provincial authority to confirm the exact process and documents needed for ExAC eligibility. In most provinces this is a separate step from IAP submission. Submit your application and pay the eligibility fee. Processing typically takes four to eight weeks, so filing in Month 2 keeps you ahead of the registration window.
Decide which November you are targeting: this year or next. Check whether your firm reimburses exam fees before you spend anything (see the employer reimbursement guide). Buy or borrow your primary references: CHOP, CHING, and NBC 2020 at minimum. Download the official ExAC Preparation Guide from exac.ca.
Month 3
Register and map the territory.
Watch for the registration window to open. For the 2026 sitting it ran from June 1 to July 10, with an experience submission deadline of June 30, which is roughly four months ahead of the exam. Missing that window means waiting a full year. Register and pay your fee as soon as the window opens.
Start your first study week: map the territory, not content. Skim CHOP Chapters 1 and 2 for the shape of Canadian practice, open CHING to the table of contents, and locate Division A in the NBC 2020. Know where everything lives. Confirm exam logistics: location, travel time, what references you are allowed to bring, and start setting up code tabs.
Month 4
Active study, first half.
Cover Section 1 topics: programming and site analysis (Functional Programming, CHOP 6.1), cost management (Yardsticks, RSMeans, CHOP 4.2), and schematic design and design development (CHING). Then begin Section 2: NBC navigation and building classification (Division A, Part 3 sections 3.1 and 3.2). Tab the code with the same tabs you will use on exam day.
Start practice questions from Week 2 of this month, not the end of Month 5. Questions expose the gaps in your reading while there is still time to close them.
Month 5
Active study, second half.
Complete Section 2: fire and life safety (NBC 3.2 to 3.4), accessibility (3.8), small buildings (Part 9), and NECB Section 3. Cover Section 3 with CHING as the primary source, supplemented by CHOP's construction-documents and sustainability content. Then cover Section 4: CCDC 2 in full, CHOP Chapters 5 and 6, and RAIC Document 6.
Revisit your IAP records to refresh the architect's roles and responsibilities under contract. Section 4 tests those roles in abstracted scenarios that do not always match what you see at your firm.
Month 6
Mock exams and exam day.
Sit a full timed mock exam at the start of the month covering all four sections. Mark it the same day. Identify your two weakest categories and re-read only those chapters. Drill targeted practice questions for one week, then sit a second full timed mock.
In the final two weeks: light review only, one-page summaries, and a final check of your NBC tabs. Confirm exam logistics one last time: how long it takes to get there, what references you are bringing, and your arrival plan. Stop studying the night before. Sleep is study.
The ExAC runs once a year, over two consecutive days in November, and registration closes in July. That single fact does most of the planning for you. If you will clear 2,800 approved hours and have your eligibility confirmed before the July window shuts, this November is live. If you will not, the answer is next November, and there is no closer option to argue about.
The second question is whether you can give yourself at least three months of active study before exam day. Registering in July for a November sitting leaves that runway comfortably, which is the one genuinely good thing about the schedule.
Do not register just because the window is open. Sitting unprepared costs the same registration fee, plus a failed result and one of your three consecutive attempts. Waiting a year is cheaper than that, though it is a real year, so make the call honestly rather than optimistically.
A few situations that commonly affect the decision:
These are the four most common ways the lead-up goes wrong. Each one is fixable in advance and expensive to fix after.
The lead-up period is where candidates add work they do not need. These are the skips worth making before Month 3 starts.
Do not rely on what a colleague did two years ago. Eligibility requirements and processing steps change. Read your regulator's current guide before submitting anything, and confirm it has not been updated since the version your colleagues used.
Download it at the start of Month 2. It sets out every exam objective with its primary and secondary reading-list references, and it is the authoritative source for what is actually tested. Reading it once before you start the books keeps you from over-reading sources that do not pay back on exam day.
Once Month 3 starts and registration is confirmed, the 3-month ExAC study plan is the plan to run. It covers Months 3 through 6 at the chapter level, with a weekly question target and a week-by-week reading order built for working interns with eight to twelve hours per week.
Start it in Month 3, Week 2. The Examitect question bank covers all four sections with scenario questions and answer explanations that point back to the source chapter. Starting in Week 2 rather than the final month exposes gaps in your reading while there is still time to close them.
Check this in Month 2, before you spend anything. Many Canadian architectural firms reimburse ExAC registration fees, study materials, or both. Some need pre-approval; others just need receipts. A thirty-minute conversation in Month 2 saves friction at registration time. The employer reimbursement guide has a request template you can adapt.
You can sit the ExAC at the first November sitting after your eligibility is confirmed, which needs Intern or Candidate status, full CACB certification and a minimum of 2,800 approved experience hours. You do not have to finish the IAP's 3,720 hours first. Allow four to eight weeks for the application to process, and remember the experience submission deadline falls at the end of June for a November sitting.
Processing time varies by province and by time of year. The busy period runs into the June and July registration window, when it can stretch to six to eight weeks. File your eligibility application as soon as your log clears 2,800 approved hours rather than waiting for the registration window to open.
No. Completing the IAP means your experience hours and competency areas are signed off. ExAC eligibility means your provincial authority has reviewed your application and confirmed you are authorized to register for the exam. They are two separate steps, and the second requires a formal application.
Apply as soon as your IAP is complete. Do not wait for the exam registration window to open. If you wait until registration opens to start your eligibility application, the processing time may push you past the registration deadline for that sitting.
Register for the sitting where you can give yourself at least three months of active study time. Count backward from the exam date and confirm the study months actually fit in your calendar. Do not register because the window is open; register because you have the runway.
In some provinces you can apply to sit certain sections before completing all IAP requirements. Check your provincial authority's current eligibility rules: they differ by province and are updated periodically. Do not assume what applied to a colleague in a different province applies to you.
There is only one sitting a year, in November, so the question is which year. Target this November if your eligibility will be confirmed and your experience submitted before the deadlines that close at the end of June, and if you can protect at least three months of uninterrupted study between July and the exam. Otherwise target next November.
Registration fees are set by each provincial architectural authority and change periodically. Check your province's current fee schedule rather than relying on a number from a colleague or forum post. Factor in the eligibility application fee, which is separate from the exam registration fee, and confirm whether your firm reimburses either or both.
You wait for the next sitting, and because the ExAC runs once a year the gap is twelve months. Use the time to confirm study materials, apply for employer reimbursement, and start mapping the territory so you are not behind when registration opens again in June.
You do not need physical copies of everything. The NBC 2020 is accessible online through NRC's website. CHOP may be available through your provincial association or your firm. CHING is commonly shared among colleagues. What matters is having your primary references within reach by Month 3: CHOP, CHING, NBC 2020, and CCDC 2 at minimum.
Light orientation is fine, but do not start the full study plan until you have a confirmed sitting. Use the waiting time to review the official ExAC Preparation Guide, decide which references you need to acquire, and check whether your firm covers fees. Full studying before you know your exam date means content fades before it matters.
If you clear 2,800 approved hours after the June experience submission deadline, that November is already closed to you and the next sitting is twelve months out. Use the extra time rather than resenting it: get the eligibility paperwork filed, secure employer reimbursement, and start the twelve-week plan in the summer of the following year rather than the autumn.
