Written Tests Were Always the Wrong Measure for Kids Who Read Differently

Last updated: July 3, 2026

Parents of children who struggle with reading know this story by heart: their child can explain the concept clearly, answer questions out loud, solve problems in conversation — and then go blank on the test. The grade does not match the knowledge. A June 2026 commentary in Policy Options by Brock University professor Louis Volante, writing from his research on cognitive and non-cognitive skills, puts the problem plainly: schools are measuring students on what is easiest to test, not what actually predicts their success. Generative AI made the cost of that mismatch too large to ignore. For children with dyslexia, the cost has always been there.

TL;DR

AI use by ~75% of Canadian students (KPMG, 2025) is forcing universities to ask whether written tests actually measure learning — but the validity problem is older than ChatGPT.

Brock University professor Louis Volante (Policy Options, June 2026) calls for a shift to "performative tasks": oral exams, case studies, portfolios, and small-group breakout sessions that measure both cognitive and non-cognitive skills.

The IDA 2025 definition establishes that dyslexia affects phonological-orthographic processing, not intelligence or oral reasoning — making written-only assessment a measurement error for these children, not a verdict on their capability.

Oral exams reduce written output pressure but add real-time cognitive, social, and executive function demands; portfolio and project-based assessment tends to be the most universally accessible alternative for diverse learners.

Parents of children with learning differences have direct language to request authentic assessment alternatives in IEP and 504 meetings — the research now backs them up.

AI is forcing universities to ask whether written tests actually measure learning. For parents of children who learn differently, that question has never been new — and the researchers’ answers point in a direction special education has argued for years. Here is what the evidence shows and what parents of struggling readers can do with it right now.

Common questions

Are oral exams always better for children with dyslexia?

Oral exams remove written output pressure, which often reveals more of what a child with dyslexia actually knows. But oral formats also introduce real-time processing demands, social anxiety, and executive function challenges that affect some children differently — especially those with ADHD or who find real-time social situations cognitively taxing. Portfolio and project-based assessment tends to be the most universally accessible alternative. The right question is not “oral or written” but which format gives your child the clearest chance to show what they actually know. A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing, or medical cause, pursue a professional evaluation — that is the only route to those supports.

What should I ask for in my child’s IEP or 504 meeting about assessment?

Ask specifically about oral assessment accommodations (answering questions verbally rather than in writing), portfolio-based grading (a body of work over time rather than a single test), and project-based alternatives to written exams. Reference the growing research on authentic assessment: multiple 2026 Frontiers in Education studies and university researchers like Louis Volante at Brock University support these formats as more valid measures for diverse learners. Name the specific processing system: if your child’s dyslexia affects written output specifically, ask what the school can do to measure content knowledge through a different channel.

Does dyslexia mean my child is less intelligent?

No. The International Dyslexia Association’s 2025 updated definition explicitly decouples dyslexia from overall intelligence — it dropped the IQ-discrepancy requirement that previously blocked many capable children from receiving support. Dyslexia affects phonological-orthographic processing: the connection between sounds and written symbols. It does not affect oral reasoning, spatial thinking, problem-solving, or any of the many systems that constitute intelligence. A child who struggles with written tests is not less capable. They are being measured by a method that disadvantages their specific processing profile.

Will schools actually change how they test kids because of AI?

Change is happening at the university level and moving slowly toward K-12. Multiple institutions are already shifting to oral exams, portfolios, and project-based assessment — health sciences and education programs especially. The research framework is now building fast. K-12 change will be slower, which is why parents advocating for specific assessment accommodations in IEP and 504 meetings are ahead of systemic change. You do not have to wait for the system to update. You can request what the research already supports right now.

What researchers are saying about written tests and why

With approximately 75 percent of Canadian students now using generative AI for coursework (KPMG Canada, October 2025), universities face a validity crisis: if AI can write a passing essay, does a passing essay actually prove a student learned anything? Louis Volante, a distinguished professor at Brock University and fellow at the United Nations University MERIT/Maastricht Graduate School of Governance, argues in Policy Options that the question goes deeper than AI integrity. His research finds that both cognitive skills (reading, math, science) and non-cognitive skills (collaboration, growth mindset, self-regulation, emotional intelligence) influence each other and both significantly contribute to educational attainment and work success. Traditional written tests measure the first set almost exclusively and largely ignore the second. The solution he calls for: a shift toward “performative tasks” — oral assessments, case studies, portfolios, and small-group breakout sessions. Multiple Frontiers in Education studies published in 2026 make the same case, proposing frameworks for authentic assessment that stress oral examination, real-world projects, and reflective writing over standardized written tests. Volante notes that health sciences, business, and education programs are already moving this direction — but “selectively, not to scale.”

The move is being driven by AI, but the validity problem it exposed is not new. “Knowledge acquisition is necessary, but insufficient, in preparing students for their futures,” Volante writes. “We need a new path forward — namely, to fundamentally change how we assess and evaluate students.”

What the coverage gets wrong

Most reporting on AI and academic integrity frames the issue as a student-honesty problem: AI makes cheating easy, so schools need better detection or harder in-person tests. What Volante's research and multiple 2026 Frontiers in Education studies show is that AI exposed a pre-existing validity problem: written tests were never a complete or neutral measure of what students know. They are especially incomplete for students whose processing profiles differ from the assumed norm. The International Dyslexia Association's 2025 definition makes clear that dyslexia affects phonological-orthographic processing, not general reasoning ability. Treating assessment reform as an AI-integrity story misses the longer and more important story: a generation of children with learning differences has been graded by a method that was measuring the wrong thing all along.

The measurement error that has always hurt children with dyslexia

For children with dyslexia, this is not a new argument. The International Dyslexia Association’s 2025 updated definition makes the mechanism clear: dyslexia affects phonological-orthographic processing — the connection between sounds and written symbols — not intelligence, not oral reasoning, not the ability to understand and discuss ideas. A child with dyslexia who reads at a fourth-grade level in fifth grade is not a fourth-grade thinker. The gap is in one specific processing modality, not across the mind. When that child sits a written test under time pressure, what the score captures is partly their processing speed and written word retrieval — not just their content knowledge. That is a measurement error. It has been costing children their academic self-concept for generations, and the education system has been slow to fix it because written tests are cheap and scalable and because the children who pay the highest price are often the ones with the least institutional power to push back.

Researchers now proposing oral exams, portfolios, and project-based evidence are not inventing something new. They are catching up to what special education advocates and parents of learning-different children have argued for decades. As Volante’s research confirms, the non-cognitive skills these alternative assessments surface — self-regulation, collaboration, persistence — are the same skills that predict long-term success. If you want to know what a child actually knows and is capable of building on, measuring across multiple systems — not just through written output — gives you the real picture. AI forced that reckoning at the university level. The reckoning needs to reach K-12 too.

Key Takeaways:

The measurement error behind a wrong grade: Written tests under time pressure measure, in part, a child's written-language processing speed and retrieval — not just content knowledge — which systematically disadvantages children whose dyslexia affects written output.

What researchers now recommend instead: Oral exams, portfolios, case studies, and project-based assessment capture both cognitive and non-cognitive skills and are supported by the IDA 2025 definition and multiple 2026 Frontiers in Education studies as more valid measures of what a student actually knows.

How parents can use this in IEP and 504 meetings: Ask specifically about oral assessment accommodations, portfolio alternatives, and project-based grading — and know the tradeoffs: oral formats help many children with dyslexia but may add challenges for children with ADHD or social anxiety.

What parents can do with this right now

The shift is not complete and it is not fast. Authentic assessment is being adopted selectively in higher education and more slowly in K-12. But knowing this trend gives parents more specific language in IEP and 504 meetings today. If your child with dyslexia or ADHD consistently performs better in conversation than on paper, that is worth naming explicitly: ask about oral assessment accommodations, portfolio-based grading, or project alternatives to written tests. These are not workarounds — a growing body of peer-reviewed research now calls them better measurements.

The tradeoffs are real and worth knowing. Oral exams remove written output pressure, which often reveals more of what a child with dyslexia actually knows. But oral formats also introduce real-time processing demands, social anxiety, and executive function challenges that some children with ADHD find harder, not easier. Portfolio and project-based assessment tends to be the most universally accessible option. The question is not “written versus oral” — it is which format gives your child the clearest chance to show what they actually know. That has always been the right question. AI just made enough people ask it loudly enough that the research community is now building the frameworks to answer it.

The assessment conversation is also not finished with a single IEP line item. Knowing specifically which of your child’s processing systems are strongest — auditory, visual-spatial, oral reasoning, working memory — lets you advocate for assessment formats that match the real picture of your child’s mind, not the distorted one a written test produces under pressure.

University programs are increasingly making use of oral assessments, case studies, portfolios and small group breakout sessions in some undergraduate courses — unfortunately, this is being done selectively, not to scale.

Your child’s grade on a written test is not a verdict on what they know. For a child with dyslexia, it has often been a measurement of how difficult their particular brain wiring makes it to get knowledge out through the written channel under time pressure. The research community is catching up to that fact because AI made it expensive to ignore. The obstacle was never your child’s mind. It was a one-modality system slow to ask whether it was measuring the right thing. Use the shift to ask louder questions about how your child gets measured — and what fairer measurement reveals about who they actually are. The Learning Success All Access gives you the multi-system framework to understand which processing routes your child is strongest through — so you know exactly what to ask for.
