Impacts of Free Community College on Degrees and Earnings

This study involves Tennessee Promise, Tennessee’s tuition-free community college program, which preceded similar programs in over twenty states and multiple federal proposals, examining how Promise affected college enrollment and early adult outcomes as the program expanded from a single-county pilot to statewide eligibility. 

Promise increased college enrollment by 5.4 percentage points among 19-year-olds, increased transfers from two-year to four-year schools, increased associate’s degree attainment by 2.9 percentage points among 21-year-olds, imprecisely increased bachelor’s degree attainment by age 24, and weakly increased income from age 21. 

The authors estimate that the program pays for itself under reasonable assumptions about returns to college.

Will The University Endowment Tax Slow Scientific Progress?

 The 2025 university endowment tax hike and other sources of financial pressure may lead the schools that train the most prolific economics researchers to reduce graduate enrollment. Will this affect long-run research output? 

This study uses a novel sample of MIT Economics PhD program applicants to estimate the research value-added of eight elite schools. The estimates mitigate selection bias by controlling for MIT admissions committee rankings—a remarkably strong predictor of long-run research success—and for applicant aspirations as revealed by their application portfolios. 

While rank controls substantially reduce estimated gaps between elite and non-elite graduates, large differences in value-added remain. Graduates of high-tax and other top-eight schools produce 60-75% more impact-adjusted publications than do comparable graduates from non-top-eight US schools. The elite-school advantage is especially pronounced for top five journal publications. Differences in research success within the elite tier, however, are relatively modest. The out-performance of elite-school PhDs does not appear to be explained by editorial connections or peer effects in elite programs.

Generative AI calls for assessment reform in higher education


Higher education must rethink assessment practices in response to the growing integrity challenges posed by generative artificial intelligence (GenAI), say authors in this Policy Forum. They analyzed data on student use of this technology across 20 major public research universities in the United States. The impact of GenAI on higher education is highly debated. In many ways, the technology is making common forms of evaluation, such as tests, projects, or term papers, less reliable as a measure of student capability. 

This highlights the need for a better understanding of where GenAI use is most prevalent and where misuse is most likely to occur. Igor Chirikov and colleagues analyzed survey data from more than 95,000 students across 20 U.S. research universities during the 2023-2024 academic year. Their findings reveal widespread GenAI use among students: roughly two-thirds of students reported using it over the study period, with 37% using it regularly. 

However, usage patterns differed considerably by discipline, with higher adoption in STEM fields. For example, 62% of computer science students reported regular usage, compared with only 24% of students in the arts. Notably, some social science disciplines, such as business and economics, also demonstrated high levels of adoption. Patterns of GenAI-assisted cheating also varied across disciplines. Estimated rates of misuse were generally higher in non-STEM fields, with economics (17%) and journalism (16%) showing relatively high rates, whereas biology (5%) was among the lowest. 

The study also found significant demographic disparities in GenAI use, with higher adoption among male, White, and Asian students than among female and underrepresented minority students. 

Although differences tied to socioeconomic status and disability were smaller, the authors suggest that the findings raise concerns about unequal access to AI tools and literacy. 

Chirikov et al. propose several paths forward. They note that there is no single “AI-proof” assessment model and suggest reforms tailored to individual disciplines. They place a focus on preparing students to use AI responsibly in professional contexts.

Widespread AI misuse by college students

  Large numbers of college students are now using artificial intelligence to complete – and cheat on – their assignments, suggesting that colleges and universities need to change how they are evaluating students, new Cornell University research finds.

An analysis of survey responses from more than 95,000 students at 20 public research universities in the U.S. finds about one-third regularly used generative AI (GenAI), such as ChatGPT or other models to produce text, video or code, when completing assignments, and 9% had used it to cheat.

“Assessment reform is necessary and urgent,” said study co-author Rene Kizilcec, associate professor of information science and director of the Future of Learning Lab. “The fact that students are misusing GenAI is a problem for assessment validity, and that’s a problem for the credibility of university credentials.”

The study, “Generative AI Use and Misuse Call for Assessment Reform in Higher Education,” published May 21 in the journal Science.

Kizilcec partnered with Igor Chirikov, director of the Student Experience in the Research University (SERU) Consortium at the University of California, Berkeley, to investigate AI use and misuse among university students. Each year, SERU sends out surveys to undergraduates, asking students’ opinions on engagement, belonging, affordability and other topics.

The questions regarding GenAI usage, collected during the 2023-24 academic year, was the largest survey of its kind at the time, which enabled researchers to break down responses by discipline.

Overall, 37% of students reported using AI at least monthly, with disciplines requiring large amounts of data analysis showing higher rates of adoption. Rates varied, with 62% of computer science students reporting regular usage, compared to 24% of students in the arts.

The survey also showed demographic differences in GenAI use. Researchers found that 33% of female students reported using GenAI regularly, compared to 45% of male students. People belonging to underrepresented racial minorities also had lower rates of regular use at 29%, compared to 39% of white and Asian students.

These demographic differences may reflect equity gaps in the use of AI tools, researchers said. Additionally, they warn these gaps may widen as GenAI tools become more specialized and costly.

To accurately estimate rates of cheating – something students may hesitate to admit – the researchers used a technique called a list randomization experiment. They provided a short list of statements and asked students how many statements – but not which ones – applied to them. By including an additional statement about cheating on some surveys but not others, they could estimate rates of AI misuse.

Overall, the number of students who had used AI to cheat was lower than anecdotal reports had suggested, researchers said. Daily GenAI users had the highest rate of cheating, at 26%, compared to 7% for those who used it monthly.

“As we expect GenAI use among students to only grow, for better and worse, we also expect that GenAI misuse will grow, which is concerning,” Kizilcec said.

The study’s authors call for changes in how universities are assessing students, to promote academic integrity. They suggest three strategies: professors could go back to highly controlled testing environments – just pen, paper and proctors; they can set clearer guidelines for acceptable AI use; or they can adapt assessments to include AI in ways that show off professional skills.

Universal free school meals improve student behavior

 

A study published in Economic Inquiry provides new evidence that universal free school meals can meaningfully reduce out‐of‐school suspensions in both elementary and secondary schools.

Using updated information and methods that more accurately account for how policies across US schools were adopted over time, the research builds on earlier conclusions showing null effects. Investigators found that adopting universal meals decreased suspensions by approximately 10% for elementary students and 6% for middle and high school students. These impacts were more pronounced in schools with fewer students who were eligible for free and reduced-price meals before the policies were adopted.

With the COVID-19 pandemic, the US Department of Agriculture granted waivers to schools for serving all students free meals since 2020, but in June of 2022, Congress rejected the federal funding required to sustain universal meals. Many states have returned to the traditional way of providing school meals (free, reduced-price, and full- price), some have decided to continue to provide free meals, and others are analyzing the costs and benefits of adopting universal school meals.

“Our findings highlight universal free meals as not just a nutrition policy, but a tool for improving school climate and equity—especially in schools that previously served fewer low‐income students,” said corresponding author Andres Cuadros-MeƱaca, PhD, of the University of Northern Iowa.

Experts warn of ‘dangerous’ rise in ADHD diagnoses as some children given unnecessary medication


Psychologists have issued a stark warning about the exponential rise in ADHD diagnoses in children, arguing that some childhood behaviours are being wrongly medicalised through a flawed and subjective diagnostic system.

The research, published in new book States of Mind, reveals that ADHD diagnoses in the West have surged dramatically in recent years, with experts questioning whether millions of children are being unnecessarily labelled as disordered, when they are instead responding to rigid educational environments.

The research, by charity States of Mind, comes from eight years of collaboration with secondary schools, sixth form colleges, community settings and supported housing organisations to examine the dynamic inter-relationship between teenagers and the education and mental health systems.

They found that young people are routinely left out of life-altering decisions, such as what environments would benefit their education and wellbeing. The authors argue these rigid systems alienate young people and leave them experiencing psychological or emotional distress – and the authors propose addressing this cause, rather than medicating the symptoms and marginalising children.

“Labelling individual children as ill or disordered does not investigate the deeper causes of psychological distress, nor enable meaning to emerge from the experience of suffering,” they explain. “Without thoroughly exploring the contextual triggers, it is not possible to genuinely consider or re-consider the core societal drivers that shape our young people’s mental health and wellbeing. In actuality, the expansion of mental health interventions, while helpful for some and likely well-meaning, are often nothing more than a sticking plaster. Unless we think together, with children and young people, about which aspects of their systemic contexts lead them to feel the way they do, our mental health provision will remain reactive and at best, marginally effective.”

One such example they cite is around diagnoses. The authors argue that the current diagnostic process for ADHD lacks scientific objectivity, relying instead on checklists that pathologise adaptive childhood behaviours, or behaviours shown in response to emotional distress.

The book highlights a fundamental flaw in the diagnostic process: children need only display symptoms in two contexts, typically home and school, to receive an ADHD diagnosis. Yet the same children may show no signs of inattention or hyperactivity when engaged in activities they enjoy, such as cooking, fishing or playing sport. This suggests, the authors argue, that the learning environment should change, not the child.

“We have met children and young people who are ‘off-the-wall’ in a classroom but can focus wholeheartedly for hours when cooking, fishing or playing sport,” the authors write. “Doesn’t this confirm that any perceived inattention or hyperactivity is triggered by one’s environment?”

The book also tackles neurodiversity, arguing that whilst the movement has made important strides in helping marginalised individuals gain a sense of security, it has inadvertently reinforced the biomedical paradigm by suggesting that some brains are fundamentally different from others.

“There is no such thing as a ‘typical’ brain, everyone is unique,” the authors argue. “Suggesting otherwise requires us to believe in a fanciful ‘average’ brain, against which forms of divergence can be measured.”

The research challenges the genetic basis often cited for conditions like autism, pointing out that no specific genes have been definitively identified despite widespread assumptions of heritability. The authors highlight significant flaws in twin studies commonly used to support genetic theories, noting that identical twins share more similar environments both in the womb and after birth than is typically acknowledged.

But above all, the authors question why children and families should require medical diagnoses to access support.

“It is extremely harmful that, at present, children, young people and families are often unable to access support without medical diagnoses,” the authors write, advocating instead for an approach where “people should be trusted to define themselves and co-construct what works in collaboration with their nearest and dearest.”

The research calls for a fundamental shift away from what it terms the “psychiatrisation of our consciousness”, arguing that educational and support approaches should be tailored to children based on who they and their families perceive them to be, rather than blunt psychiatric labels imposed by external authorities.

“There is not, and never can be, a single understanding of childhood as a stage of the human life cycle, nor a fixed way of instructing or nurturing. Pretending there is and cementing things in place, as we have done with schooling and the biomedical model of healthcare, create a disposition of the modern, Western mind. These decisions are political. They are not educational or scientific,” they argue.

“In sum, believing that we have discovered the universal way to educate, through schooling, is profoundly unreasonable. Believing that we can objectively label some people abnormal, then medicate them back to normality is delusional. In a desperate yearning for certainty we coerce and control, we marginalise and harm many children. And those children carry those harms into adulthood. It doesn’t have to be this way.”

The authors advocate for institutions that can respond to individual human beings without being dependent on psychiatric labels, considering instead how children think, feel and present in the world.

“We suggest that people should be trusted to define themselves,” the authors conclude, “and this does not require submission to the dubious jurisdiction of the biomedical paradigm.”

The authors instead argue for education and mental health systems to have authentic and participatory feedback mechanisms in place for improving the system and supporting one another’s health and wellbeing.

States of Mind have demonstrated that an approach grounded in ‘liberation dynamics’, where young people are active participants, rather than passive recipients, provides space for the co-design of meaningful solutions that genuinely address their needs.

“Anyone can do this work and what is needed is not extra resources or extraordinary expertise, but a shift in our imagination about who we are and what is possible. It starts with recognising that something needs to change, then becoming the change ourselves,” they conclude.

Nearly 60 Percent of College Students with a Psychosis Diagnosis Are Not Receiving the Recommended Mental Health Treatment


Although the majority of students sought and received therapy or counseling in the past 12 months, less than 40 percent received the recommended combination of therapy/counseling and antipsychotic medication, suggesting potential barriers to accessing this medication.

Despite a low overall prevalence of psychosis in the United States, affecting three percent of the population, this condition is a serious public health concern because people often delay seeking care for an average of 74 weeks from the time symptoms begin. As psychosis tends to emerge in early adulthood, it’s important to understand the reasons why young adults who experience psychosis seek—or do not seek—mental health treatment. 

A new study led by a Boston University School of Public Health (BUSPH) researcher examined the perceptions, beliefs, and attitudes that influenced college students’ with a diagnosis of psychosis to seek help for their mental health and found that while a majority of these students believed they needed mental health treatment, 60 percent of students did not meet current recommended guidelines for combined antipsychotic medication and therapy. 

Published in the journal Social Psychiatry and Psychiatric Epidemiology, the study found that nearly 8 in 10 surveyed college students with psychosis reported needing mental health support. While 8 in 10 students did seek therapy or counseling within the past 12 months, only 4 in 10 students reported taking antipsychotic medication. 

“This high identified need for help but low utilization of services indicates potential barriers to accessing this care,” says study lead and corresponding author Clara Godoy-Henderson, a PhD student in health services and policy research at BUSPH. “Early intervention and access to services such as therapy and medication in this population are important because it improves outcomes related to overall quality of life, school involvement, employment, symptom severity, and relapse rate.”

The study is among the largest to assess the use of antipsychotic medication, therapy/counseling, and informal support among college students with psychosis. As the average age of onset of psychosis is about 20 years old, understanding college students’ perceptions and behaviors around treating this condition can help identify opportunities for earlier interventions that could improve psychosis outcomes.

For the study, Godoy-Henderson and colleagues at BUSPH and the University of Minnesota analyzed national survey data from the Healthy Minds Study, the nation’s largest survey of student mental health, conducted by the Healthy Minds Network. The researchers examined responses from 2,819 college students with a diagnosis of psychosis, provided between 2015-2024, about their 12-month history with therapy/counseling and antipsychotic medication, as well as whether informal support from various groups around them (friends, loved ones, roommates, campus staff, religious counselors, or support groups) motivated them to seek or utilize these services.

Overall, the majority of students—nearly 60 percent—believed that they needed help for their psychosis condition. Students who did not believe they needed mental health help—or who believed that therapy/counseling and medication would not be helpful in treating their condition—were less likely to seek and receive these services. Still, the high identified need for help, but low utilization of antipsychotic medication, may indicate that students are encountering barriers to care, such as stigma—an issue that is also the focus of this year’s Mental Health Awareness Month, an awareness campaign held each May by the National Alliance on Mental Illness. 

The findings also suggested that college students who believed they needed mental health treatment were more likely to have received informal support from health professionals or friends, and were more likely to take antipsychotic medication and/or receive therapy/counseling if they were encouraged—versus being pressured or forced to seek help, as is often the case when patients can be institutionalized for their mental health.

"Support systems play a crucial role in identifying early psychosis symptoms and help navigate mental health services, which may be an important factor in treatment initiation,” says Godoy-Henderson. “However, future research should examine the long-term outcomes of individuals who are encouraged by their support systems to seek help for their mental health versus being mandated to treatment.”

Future research should also aim “to better understand the barriers to antipsychotic medication to improve poor outcomes, such as delayed care, and high relapse rates in individuals with psychosis,” she says.
