The Traumatic Impact of Retention

What I Watched Before I Knew the Research

Before I had an Ed.D. or two decades of clinical practice, I was raising five neurodiverse sons. I watched what repeated academic struggle does to a child. The research has since confirmed what I watched.

When researchers ask children directly, the answer is consistent.

“Early adolescents often identify grade retention as one of the most stressful life events they could experience.”

That finding is not from a single survey. Multiple studies, across countries and two decades, have replicated it (Anderson et al., 2005; Leontopoulou et al., 2011; Pipa et al., 2024). Inside an IEP or 504 meeting, this rarely gets named that way.

Why Repeating the Same Year Does Not Fix It

Retention is built on the assumption that the problem is exposure. Not enough time, not enough practice, not enough effort. For children with learning differences, that is rarely the problem. The problem is the method.

Reading instruction that does not include explicit, systematic phonics will not teach a dyslexic brain to read no matter how many times it is repeated. Math instruction that skips the multisensory foundation will not build number sense in a child with dyscalculia. Writing instruction that asks a child with dysgraphia to try harder will not address the motor planning and orthographic processing that is actually breaking down.

When a child works hard for nine months and the instruction was not designed for the way they learn, asking them to do the same nine months again, harder, is not a plan.

There is a narrow case where retention helps. A typically-developing child who missed half a year to illness or family disruption may benefit from another pass at grade-level content. For a child with a learning difference, the calendar was never the problem.

What the Current Research Documents

Causal harm	A 2024 regression discontinuity study of New York City public schools found that retention reduces high school credit accumulation, reduces the likelihood of taking math and English Regents exams, increases dropout for middle grade students, and increases later placement into special education (Mariano, Martorell, & Berglund, 2024).
Three follow-ups	A 2025 longitudinal study tracked students at three follow-up time points and found that retained students showed engagement decline at every measurement, with the steepest drops in study behaviors and in the family support students perceived around their learning (Sousa et al., 2025).
36.5%  |  26.3%	In a 2024 study of 2,322 primary school students, dyslexic children showed depression symptoms at 36.5% and anxiety symptoms at 26.3%, alongside lower self-esteem and higher rates of being bullied (Feng, Chotipanvithayakul, & Liu, 2024). These rates compound when a child spends another year repeating instruction that was never built for their brain.
School connection	A 2024 study including 87 children with dyslexia found that school-connectedness mediated the link between dyslexia and anxiety, depression, and conduct problems. When school-connectedness goes, the mental health risks rise (Wilmot et al., 2024).

What Happens Inside the Child

Repeated academic failure shapes the brain. Year after year, the same message lands: I am the kid who cannot do this. Children develop learned helplessness, a state in which the brain stops attempting tasks it has come to expect failure on. The stress response that fires during reading, math, or writing tasks pulls energy away from the very systems the child needs to learn: working memory, executive function, sustained attention.

For a child whose executive function or attention regulation was already a weak system, retention puts that already-struggling system under sustained stress for another full year. Sousa’s 2025 data shows engagement does not stall. It drops.

Why Retention Fails Each Learning Difference

More of the same teaching cannot fix a learning difference, also clinically categorized as a specific learning disability. Each of these conditions is a mismatch between how a child’s brain processes information and how the standard classroom delivers it. Repeating a year does not change the delivery. It changes the calendar.

Dyslexia. Reading in most classrooms is taught through exposure to text and context-based decoding, on the assumption that the connection between sounds and letters forms naturally. For a dyslexic brain, it does not. These children need explicit, systematic instruction in the phoneme-to-letter code, taught in sequence. A meta-analysis of forty years of reading intervention research found a positive effect of targeted intervention on reading outcomes (g = 0.33), with higher dosage producing larger effects.Hall et al., 2023, Reading Research Quarterly

Dysgraphia. Standard writing instruction asks children to practice handwriting and produce more written work. For a child whose brain cannot reliably coordinate the motor planning and orthographic retrieval that handwriting requires, more practice does not build the missing process. They need direct instruction in letter formation, multi-modal scaffolding, and often assistive technology. A 2025 review of two decades of dysgraphia intervention research found that structured, individualized, multi-modal intervention is what improves writing outcomes.Han & Wang, 2025, Children (MDPI)

Dyscalculia. Standard math instruction is built on memorizing facts and drilling procedures, on the assumption that the child already feels numbers the way most children do. A child with dyscalculia does not. The curriculum stacks new procedures on a foundation that is not there. They need instruction that builds number sense from the ground up and adapts to the specific deficits each child is presenting. Recent research on personalized, adaptive math intervention demonstrated significant improvements in numerical abilities when instruction was matched to the child’s specific number-sense profile.Jadhav et al., 2025, European Journal of Investigation in Health, Psychology and Education

ADHD. A standard classroom is built on the expectation that children can sit, focus, manage time, and complete tasks independently. For a child with ADHD, those regulatory systems do not function reliably, regardless of effort. They need environmental modifications, behavioral scaffolding, and explicit instruction in self-management. A 2025 meta-analysis of school-based randomized controlled trials found targeted interventions significantly improved core ADHD symptoms, academic performance, and social skills.Yegencik, Bell, & Deniz, 2025, Frontiers in Psychology

Executive Functioning. Classroom expectations assume children can plan, organize, sequence, and self-monitor on their own. A child with weak executive function cannot, and assigning more work that requires those skills does not develop them. Executive function has to be taught directly: planning systems, multi-step task breakdown, scaffolds for task initiation. The same 2025 meta-analysis found measurable improvement in inattention and academic outcomes when school-based programs explicitly targeted these areas.Yegencik, Bell, & Deniz, 2025, Frontiers in Psychology

What Actually Works

The mechanism the current research keeps pointing to is the same one I see in our families every week. The instruction has to match the way the child learns. Structured literacy for the dyslexic brain. Multisensory math built around number sense for the dyscalculic brain. Explicit motor and orthographic intervention for dysgraphia. Direct instruction in executive function and accommodations that fit the child for ADHD.

Traditional tutoring buys time. It does not change the instructional model the child returns to every weekday. A child with learning differences may not function in a regular school for years without the right remediation.

That is what READ Academy of Sacramento exists to provide. We are a WASC-accredited private school built specifically for students with dyslexia and language-based learning differences. Every classroom uses structured, evidence-based instruction designed for the way these children process language and numbers. Wilson Reading System for reading. Making Math Real for math. Institute for Excellence in Writing for writing. The instruction itself was built for these brains, not adapted to them after the fact.

The school year is not the variable. The instruction is. Change the instruction.
