The gap between finishing the Internship in Architecture Program and sitting your first ExAC is longer than most interns expect. There is an eligibility application, a registration window that closes before you notice it, and a study runway that only makes sense once you know which sitting you are targeting. This post maps the six months between those two events so you can move through them without missing a deadline.
| Planning window | 4 to 6 months from IAP completion to exam day |
|---|---|
| Administrative phase | Months 1 to 2: eligibility application and registration |
| Study runway needed | At least 3 months of active study |
| ExAC sittings | Spring and fall each year |
| Eligibility processing | 4 to 8 weeks (varies by province and period) |
| Most common mistake | Registering for a sitting without enough study runway |
You have completed the Internship in Architecture Program (IAP), or you are within six months of completing it. You know the ExAC is next. What you are not sure about is the sequence: when to apply for eligibility, whether to target the spring or fall sitting, 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 completed the IAP more than a year ago and have already confirmed your eligibility, skip directly to the 3-month study plan. This post is for the candidate still in the gap between IAP completion and exam registration.
The cards below map the six months from IAP completion to exam day. Months 1 and 2 are administrative. 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. Confirm every required competency area has a sign-off from a licensed architect. Submit your IAP completion 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 sitting you are targeting: spring or fall. 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 study plan PDF from your provincial authority or the CACB.
Month 3
Register and map the territory.
Watch for the exam registration window to open. Registration typically closes six to eight weeks before the exam date. Missing this window means waiting for the next sitting. Register and pay your fee once 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 2.2 to 2.5), cost management (Yardsticks, RSMeans, CHOP Chapter 4), 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 is offered twice per year. Most interns who complete the IAP in the first half of the year (January to June) can reasonably target the fall sitting. Interns who complete it in the second half (July to December) typically aim for the spring sitting the following year.
The only question worth asking is: can you give yourself at least three months of active study before exam day? If yes, register for that sitting. If no, wait for the next one.
Do not register for the nearest sitting just because it is closest. Registering without study time and then sitting unprepared costs the same registration fee, plus a failed result you will carry forward. Waiting six more months is cheaper in every sense.
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 maps every exam category to 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 as soon as you have received eligibility confirmation from your provincial architectural authority. Allow four to eight weeks for your application to process after IAP completion. Most candidates sit their first ExAC six to eight months after completing the IAP, once the administrative steps and study runway are factored in.
Processing time varies by province and by time of year. Busy periods around spring and fall sittings can stretch processing to six to eight weeks. File your eligibility application as soon as your IAP log is complete 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.
Target the sitting that gives you at least three months of uninterrupted study after registration is confirmed. For most interns who complete IAP in the first half of the year, that is the fall sitting. For those completing IAP in the second half, it is usually the following spring. The closer sitting is only right if the study runway is actually there.
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. The ExAC runs twice a year, so the gap is typically six months. Use that time to confirm study materials, apply for employer reimbursement, and start mapping the territory so you are not behind when registration opens again.
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 study plan PDF, 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.
Count forward from your IAP completion date to the spring exam date. Subtract six weeks for the eligibility application and registration process. What remains is your available study time. If it is less than twelve weeks, target the fall sitting instead. Sitting unprepared costs more than waiting six more months.
