How NCA Exams Are Marked: An Examiner's-Eye View
Most people preparing for the NCA exams fixate on the wrong number. They hear "pass is 50%" and relax, or they hear "internationally-trained lawyers fail these" and panic. Neither reaction helps, because both miss what is actually happening on the other side of the desk. Someone reads your answer. That person is deciding, paragraph by paragraph, whether you have earned a mark. If you understand how that decision gets made, you can write to it. If you do not, you can know the law cold and still come up short.
This post is the examiner's-eye view of marking across the five core subjects — Canadian Constitutional Law, Canadian Criminal Law, Canadian Administrative Law, Foundations of Canadian Law, and Canadian Professional Responsibility. It explains what "50% is a pass" really means, where the marks live on a written answer, and why open-book does not mean easy.
What "50% is a pass" actually means
The NCA exams are pass/fail, and the pass mark is 50%. That sounds generous. Half wrong and you still clear the bar? People coming from jurisdictions with brutal curves or 65% thresholds often read this as a gift.
Here is the catch. Fifty percent does not mean "get half the facts right." It means the examiner, reading your whole answer, is satisfied that you have done half of the lawyer's job on the page. On a fact-based essay or short-answer question, marks are not sitting there waiting to be collected for correct statements of law. They are awarded for the work of resolving the problem in front of you. A lot of candidates write an answer that is 90% accurate as a summary of the law and still lands under 50%, because a summary of the law was never the question.
Treat 50% as a floor of competent legal reasoning, not as "half marks for showing up." Once you see it that way, the rest of how marking works starts to make sense.
The four things NCA examiners score
Across every core subject, a written answer is marked against the same four criteria. They are not a checklist you tick once; they run through the whole response, and they do not carry equal weight. But it helps to name them exactly, because each one is a place where marks are won or lost.
1. Identification of relevant legal issues
NCA questions are fact-based for a reason. The facts are salted with triggers — a search without a warrant, a delegated decision-maker who gave no reasons, a lawyer who took on a client whose interests collide with an existing one. The first thing an examiner checks is whether you saw what the facts were putting in front of you. Miss the issue and everything downstream is unreachable; you cannot earn analysis marks on a point you never raised. Candidates who read too fast, or who pattern-match to the topic they revised hardest, routinely answer a question the exam did not ask.
2. Explanation of key terms and concepts
Once you have the issue, you have to explain the law that governs it — define the key terms, set out the governing test, and unpack the framework accurately and precisely. "The Charter protects against unreasonable search" is not the same as explaining the section 8 analysis and the reasonable-expectation-of-privacy framework. This is one of the two most heavily weighted criteria, and it is the part open-book study is genuinely good for: you can carry your notes in. But a correct explanation of the law sets the marks up; it does not, by itself, collect them.
3. Evidence of critical analysis
This is the single most heavily weighted criterion, and it is where most losable marks live. Critical analysis means taking the test you just explained and running the actual facts through it — this fact cuts toward the Crown, that one raises a doubt, this factor makes the delegate's decision unreasonable on the record given. It is the difference between "here is the law on X" and "here is what the law does to these people in this problem." This is where applying the law to the facts is rewarded, and examiners give it more weight than any other single thing on the page.
The candidates who struggle most are often the ones who know the law best. They write a beautiful, accurate statement of the doctrine and then stop, as if the facts were a formality. On the page, that reads as an answer that never engaged the problem. If you want a single lever to pull, this is it: for every legal point, ask "so what, on these facts?" and write the answer to that question. Our longer guide on how to write NCA open-book answers works through what strong application looks like line by line.
4. Citing and applying key cases and readings
The fourth criterion is its own thing: citing the leading cases and prescribed readings and — the part candidates forget — actually applying them. Naming Oakes or Grant earns little on its own; the marks come from putting the authority to work, using the case's reasoning on the facts in front of you. It carries the least weight of the four, but it is genuinely scored: an answer that grounds each step in the right authority reads as a lawyer's, not a student's. Miss the case entirely and you leave those marks on the table.
None of this is about structure for its own sake. IRAC — issue, rule, application, conclusion — is not a fifth scored criterion; it is simply the discipline that forces the four onto the page in an order the examiner can follow. Answer the question asked, in the order the facts raise the issues, and give each of the four a visible home — poor structure will bury a good answer, even if it cannot rescue an empty one.
Why open-book does not mean easy
The NCA exams are open-book, three hours, online-proctored, with hard-copy notes only — no devices, no digital search. Candidates hear "open-book" and assume the difficulty drains out of it. The opposite tends to be true, and understanding why tells you a lot about what is being tested.
If you can look the law up, then knowing the law is no longer what distinguishes a pass from a fail. Everyone in the room has the same notes. What you cannot look up is judgment: which issue the facts raise, which of your fifty pages of notes is the relevant one, and how the test applies to this specific scenario. That is precisely what the marking rewards. Open-book shifts the whole exam onto the skill that is hardest to fake — the critical analysis that applies law to facts under time pressure — and away from the one that is easiest to prepare, recall. Time is the other trap. Three hours feels long until you are flipping through a binder for authority you half-remember while the clock runs. Well-tabbed, sparse notes beat a comprehensive brick you have to read in the exam.
The gap most self-studiers never close
Here is the quiet problem with self-study. You can read every case, make immaculate notes, and do a dozen past questions, and still walk into the exam never having had a single answer marked. You have graded your own work — and you graded it as the person who wrote it, which is the one perspective an examiner never has. You genuinely cannot tell whether your writing earns marks, because you have never seen it through the eyes of someone deciding whether it does.
That gap is exactly where candidates get surprised on results day. It is also the whole reason feedback exists in legal education: an outside reader tells you where your answer stopped short of the mark, and you adjust. Without that loop, you are optimizing blind. This is the void NCA Edge is built to fill. Its AI examiner, Lexi, marks written answers on the same four criteria the NCA uses — identifying the issues, explaining the key concepts, citing and applying the leading cases, and, above all, critical analysis — and shows you where marks were won and lost, so you close the gap before exam day instead of discovering it after.
What this means for how you prepare
If marking rewards judgment over recall, your preparation should too. Reading and re-reading notes builds recognition, not the ability to produce a marked-worthy answer under pressure. The fix is to write full answers to fact patterns, timed, and then get them assessed against what examiners actually score — not against whether you "mentioned" the right case, but whether you applied it.
It also means being strategic about where you spend effort. Some subjects reward tight issue-spotting; others turn on careful analysis of a single dense framework. Our breakdown of the NCA subjects ranked hardest to easiest can help you allocate study time. And if a sitting has already gone against you, marking feedback is the fastest way to diagnose why — the resit plan for a failed NCA exam starts from exactly that question. You get three attempts per subject, with roughly ten to twelve weeks between results and the next sitting, so a clear read on what cost you marks is worth more than another pass through your notes.
The one thing to take away
NCA examiners are not trying to trick you, and they are not looking for a perfect answer. They are looking for evidence that you can do what a lawyer does: identify the issue, explain the governing law, bring the right authority to bear, and — above all — reason from the law to the facts in front of you. Fifty percent is a pass because fifty percent is where that competence starts to show. The candidates who clear it comfortably are almost always the ones who practised the doing, not just the knowing — and who found out, before exam day, whether their writing earned the marks.
If you have never had one of your answers marked, that is the gap to close first. Write a real exam-style question and have Lexi mark it at NCA Edge. You will see exactly where your marks are — and where they are leaking — while there is still time to do something about it.
