Do Exams Really Prove Anything?
Why It’s Time to Rethink Assessment
In the wake of the NZ government’s recent announcements on changes to NCEA, one issue has dominated headlines and social media threads alike: exams. The reforms, which include proposals to adjust the balance between internal assessments and external examinations, have reignited familiar arguments. Some see them as necessary to restore “rigour,” while others worry they’ll undo years of progress towards more flexible, equitable assessment.
Yet amid this noise, one assumption often slips by unchallenged: that exams are an essential rite of passage every student must endure. But is this belief grounded in evidence, or just tradition?
What Do Exams Actually Measure?
At their core, traditional exams measure a narrow set of skills:
Memory recall under time pressure
The ability to write coherently and quickly in silence
Resilience under high-stress, artificial conditions
While these may sound worthwhile, they reflect only a fraction of what we value in education. Exams rarely measure creativity, critical thinking, collaboration, or the capacity to apply knowledge to complex, real-world situations, the very skills we claim are essential for life beyond school.
Cognitive science tells us that knowledge retrieval is important for learning, but timed, high-stakes retrieval under exam conditions is a poor proxy for true understanding. A student may successfully memorise and reproduce information without being able to use or transfer it. Conversely, another student might deeply understand a topic but struggle to recall it under pressure or translate it into rapid written form.
This means exams often measure exam technique as much as (if not more than) genuine mastery.
Why Exams Are a Poor Indicator of Achievement
Several flaws make exams an unreliable measure of learning:
Context Dependence: Research shows that what we remember is influenced by the context in which we learned it. Exams strip away context, meaning students are often tested in conditions completely unlike those where learning took place.
Stress Effects: High stress impairs working memory and recall. Students who experience test anxiety (estimated to affect 10–40% of learners) are unfairly penalised, even if they know the material well.
Snapshot Assessment: Exams capture performance at one moment in time, disregarding effort, improvement, or consistency. They favour those who can peak on the day, not those who have learned steadily over the year.
Narrowness: Exams prioritise topics that are easy to test in written form, sidelining skills like inquiry, communication, and collaboration. They shape learning around what is assessable, not necessarily what is valuable.
In short, exams are not designed to measure the breadth of what it means to be educated. They are efficient for ranking, but poor at recognising growth, depth, or authentic capability.
The 'We Suffered, So Should They' Mindset
There’s a troubling nostalgia at play here. Generations who endured exams seem to view them as a shared hardship to be passed down, as if academic stress builds character by default.
But education isn’t an endurance trial. Do we really want students to emerge from school more tested than taught, more anxious than equipped?
If Exams Were the Gold Standard, Why Do We Abandon Them at Higher Levels?
If traditional sit-down exams were truly the pinnacle of rigour, why do they virtually disappear as students progress through tertiary study?
At undergraduate level, assessment begins to diversify: essays, projects, lab work, and presentations become central. By Masters level, exams are rare. Instead, students engage in extended research, complex written theses, and presentations of work to demonstrate critical analysis, synthesis, and independent thought.
At the doctoral level, the culmination of learning isn’t a three-hour written paper. It’s the viva voce: an oral defence where candidates discuss their research with expert examiners. Though formally labelled an “exam,” the viva is nothing like the high-stakes, time-pressured tests of school.
Instead, it is a professional, dialogic assessment - a structured conversation that probes understanding, challenges assumptions, and explores the implications of the candidate’s work. It assumes that deep expertise cannot be compressed into bullet-point answers written at speed. It recognises that mastery is demonstrated through reasoning, dialogue, and application, not mere recall.
This should prompt us to ask:
If we don’t assess PhD candidates - the highest level of academic achievement -through traditional exams, why are we so attached to them at secondary level?
If higher education trusts authentic, discursive methods to test deep knowledge, why do we persist in using methods for teenagers that even universities leave behind?
The Mismatch Between School and Lifelong Learning
The contrast between school exams and tertiary assessment exposes an uncomfortable truth: exams often linger in schooling not because they are best practice, but because they are efficient for ranking large cohorts.
Yet the world beyond school - university, workplace, community life - values very different abilities: collaboration, critical thinking, applied expertise, and adaptability. In no professional context are we asked to sit silently for three hours and reproduce memorised content from scratch.
When the apex of academic assessment abandons traditional exams in favour of richer, more authentic demonstrations of learning, shouldn’t schools take note?
What Could Replace Exams Without Losing Rigour?
Rejecting exams doesn’t mean lowering standards, it means rethinking what meaningful assessment looks like:
Project-based tasks tied to real-world scenarios
Oral presentations or defences that measure understanding and communication
Portfolios showcasing growth over time, not just performance on one day
Collaborative problem-solving that mirrors the skills modern life demands
These approaches don’t just ask, "What do you know?" They ask, "What can you do with what you know?"
Time for Courage, Not Comfort
The debate over NCEA is an opportunity to do more than tinker at the edges. Instead of clinging to inherited traditions, we can build a qualification system that values creativity, critical thinking, and capability, not just compliance under time pressure.
Exams may still have a role, but they should be a tool, not a rite of passage.
What if, instead of preparing students for exams, we prepared them for life?

Great Article Dr Sarah,
Full disclosure, I was part of the 2nd cohort of Kiwi Kids to go through NCEA. It was stressful as heck, but having that variety of subjects & methods of assessment was the thing that kept me going as a student. I like to call it psychological seasoning.
Having all that work during the year go towards our final grade was also part of the motivation. All the essays, presentations, tests, reports etc that we did during the year all had credits we could earn & put towards our final grade, including the end of year exams.
I don't think people realize how invaluable this variety is.
I also think that no matter what system we change to, if it continues to be underfunded, much like the past 40 years, it's still going to under perform.
As a former teachers pet, I had two HODs tell me (when I was a student), that ideally HODs should have their own secretary/admin. They told me, that would make a world of difference to them & their ability to do their job. They can then focus more of the nuts & bolts of curriculum & teaching while the paperwork aspects could be taken care of by another person.
I agree, NCEA is without a doubt a lot of work for teachers, let alone students.
I wished schools got the much needed funding & resources they need. It would be the most Positively impactful & meaningful change to our education system, more so than what ever system changes governments try to do.
NCEA was created and designed to allow the assessment of cross curricular, project based, collaborative learning. Once again, as is so often the case, the professional development needed to switch to this way of teaching and learning, was not provided; secondary systems and structures are still not set up in most schools to support implementation; leaders and innovative teachers are unable to allow the intended outcome to tbrive under such constraints. Its not NCEA that needs scrapping it is the time, resources and reflective inquiry that needs to be provided to allow it to thrive.
