(Press-News.org) A new University of Oregon review of 11 studies found little evidence that the four-day school week benefits student academic performance, attendance, behavior or graduation rates.
The HEDCO Institute for Evidence-Based Educational Practice at the UO conducted the systematic review, a rigorous analysis of the highest-quality research available on the four-day school week in the United States.
“Districts often turn to four-day school weeks to address budget and staffing pressures, but the evidence suggests this change may come at a cost to students,” said Elizabeth Day, a research assistant professor at the HEDCO Institute and part of the team that produced the report. “There’s no consistent evidence that moving to a four-day schedule improves learning outcomes — and in some cases, it may do the opposite.”
The four-day school week schedule is a growing trend in U.S. education, with adoption by 2,100 schools in more than 850 school districts. The schedule is more common in rural areas, but an increasing number of suburban and urban districts are considering it.
The HEDCO Institute review findings paint a complex picture, one that differs based on school location (rural vs. non-rural), grade level and student outcome.
Key Findings:
No statistically large positive effects were found for any student outcome in the highest-quality studies.
Rural districts have been studied more rigorously than non-rural districts and no studies included just city schools.
In rural districts, evidence was mixed and suggested a four-day school week:
Decreases math and reading achievement for K-8 students
Increases math scores, increases on-time and 5-year graduation rates for high-school students
Decreases on-time progression, and increases chronic absences for high school students
In non-rural districts:
Little to no effect on K-8 student achievement
Decreases math scores, decreases on-time and 5-year graduation rates, and increases absences for high school students
For studies combining rural and non-rural districts, most findings were negative:
Decreases math and reading achievement, increases absences and chronic absences, and decreases 5-year graduation rates across grades K-12
The HEDCO Institute review highlighted two critical unanswered questions:
How much instructional time is lost or preserved?
Maintaining instructional hours is important for minimizing negative impacts on student achievement. Loss of learning time risks a loss of learning.
What do students do on the fifth day?
Without school, home or community-supported programs, students may lack access to safe, age-appropriate activities — putting their development and well-being at risk. Maintaining activities that foster healthy youth development on the fifth day is important for minimizing other negative impacts.
The review focused exclusively on student outcomes, including:
Academic achievement: math and reading test scores, proficiency and gains
Academic attainment: graduation rates, dropout rates and on-time progression
Attendance: average daily attendance, fraction of students absent, chronic absenteeism
Criminal activity: frequency of crime at school and of crime not at school, property crime, violent crime and drug violations
Disciplinary incidents: days missed for discipline, and frequency of substance use, vandalism, bullying, fighting, weapons, truancy, and school bus disciplinary instances

Using music to explore the dynamics of emotions
2025-06-30
How does the human brain track emotions and support transitions between these emotions? In a new eNeuro paper, Matthew Sachs and colleagues, from Colombia University, used music and an advanced approach for assessing brain activity to shed light on the context dependence and fluctuating nature of emotions.
The researchers collaborated with composers to create songs that evoked different emotions at separate time points. They then assessed the brain activity of study participants as they listened to these songs. Sachs ...
How the brain supports social processing as people age
2025-06-30
Because aging weakens cognitive skills, older people can struggle to read difficult social cues. A brain region involved in attention and arousal—the locus coeruleus (LC)—helps with complex tasks, and its connections to the cortex may adapt as humans age to support cognition. To shed more light on this, Maryam Ziaei, from the Norwegian University of Science and Technology, and colleagues explored whether the LC and its cortical pathways change over time to help process faces that are difficult to read.
In their new JNeurosci paper, the researchers imaged the brains of young (21 to 29 years old) and old (67 to 75 years old) adults as they looked at faces. Older adults ...
Túngara frog tadpoles that grew up in the city developed faster but ended up being smaller
2025-06-30
With 8.2 billion people in the world, cities are constantly expanding, rapidly altering the environment. Animals that undergo complete metamorphosis, such as frogs, may face bigger challenges as they try to survive in new and changing conditions, because their young stages, the eggs and tadpoles, are more vulnerable.
Scientists at the Smithsonian Tropical Research Institute in Panama (STRI) compared the development of tadpoles of Túngara frogs (Engystomops pustulosus) in urban and forest conditions. Túngara frogs, whose mating calls sound like they’ve come straight out of a video game, lay their eggs in foam nests inside puddles. The eggs become tadpoles and, ...
Where there’s fire, there’s smoke
2025-06-30
Earlier this year, wildfires in southern California killed 30 people, destroyed more than 18,000 homes and burned more than 57,000 acres. The fires were a stark reminders of the threat of worsening climate change, and the increased likelihood of future devastating fires. With these fires comes smoke, which has long-term health effects for the people exposed to it – whether they are close to the source, or many miles away.

UCLA researchers uncover key mechanism of brain repair in vascular dementia, revealing promising therapeutic target
2025-06-30
A new study from UCLA Health has uncovered how inflammation in brain blood vessels exacerbates damage in vascular dementia and demonstrated that targeting this process with a repurposed drug can promote brain repair and functional recovery in mice.
Published in Cell, the research combines laboratory and human data to pinpoint a critical signaling pathway that could lead to the first effective treatment for this understudied form of dementia.
Vascular dementia is the second leading cause of dementia. This disease co-occurs with Alzheimer’s disease in the leading cause of dementia, termed “mixed dementia.” There is no drug therapy that ...
Why Human empathy still matters in the age of AI
2025-06-30
A new study finds that people value empathy more when they believe it comes from a human—even if the actual response was generated by AI. Across nine studies involving over 6,000 participants, the research reveals that human-attributed responses are perceived as more supportive, more emotionally resonant, and more caring than identical AI-generated responses.
A new international study led by Prof Anat Perry from the Hebrew University of Jerusalem and her PhD student – Matan Rubin, in collaboration with Prof. Amit Goldenberg researchers from Harvard University and Prof. Desmond C. Ong from the University of Texas, finds that people place greater emotional value on empathy ...
COVID-19 and cognitive change in a community-based cohort
2025-06-30
About The Study: This cohort study of older participants found accelerated decreases in cognition among individuals hospitalized for SARS-CoV-2 infection, but not nonhospitalized infection, in comparison with individuals not yet infected. These findings suggest that avoiding severe SARS-CoV-2 infection could help preserve cognitive function among older adults.

Intent to test for COVID-19 in the postpandemic era
2025-06-30
About The Study: Nearly one-third of U.S. adults would not or might not test for suspected COVID-19, largely because they do not see value in testing, according to the results of an online national survey. Test hesitancy may delay oral antiviral initiation and could result in missed opportunities to limit transmission. Efforts are needed to increase awareness of the value of testing.

Landmark study investigates potential of Ambroxol, a cough medicine, to slow Parkinson’s-related dementia
2025-06-30
LONDON, Ont. – Dementia poses a major health challenge with no safe, affordable treatments to slow its progression.
Researchers at Lawson Research Institute (Lawson), the research arm of St. Joseph’s Health Care London, are investigating whether Ambroxol - a cough medicine used safely for decades in Europe - can slow dementia in people with Parkinson’s disease.
Published today in the prestigious JAMA Neurology, this 12-month clinical trial involving 55 participants with Parkinson’s disease dementia (PDD) monitored memory, psychiatric symptoms and GFAP, a blood marker linked to ...
Finding suggests treatment approach for autoimmune diseases
2025-06-30
An engineered protein turns off the kind of immune cells most likely to damage tissue as part of Type-1 diabetes, hepatitis, multiple sclerosis, shows a new study in mice.
In these autoimmune diseases, T cells mistakenly target the body’s own tissues instead of invading viruses or bacteria as they would during normal immune responses. Treatments focused on T cells have been elusive because blocking their action broadly weakens the immune system and creates risk for infections and cancer.
Published online June 30 in the journal Cell, the study revealed that holding closely together two protein groups (signaling complexes) on ...
