My expectations for tomorrow's Congressional hearing with district superintendents are not high: “Some members of Congress, especially in an election year, would rather talk about anything other than their unrelenting support for an unpopular president and an unpopular war and economic precarity."

📵 This just in: results of the first large study of cell phone bans in U.S. schools, from SIEPR's Hunt Allcott, @tomdee.bsky.social and Matthew Gentzkow. Key findings + links to @nytimes.com exclusive + study ⬇️ #EducationPolicy
School phone bans are popular with parents, teachers, & policymakers. But are they working? Using national data on the sale of lockable pouches to schools, our new study indicates they sharply reduce phone use but have mixed effects on outcomes. www.nytimes.com/2026/05/04/u...

I'm pleased to be in DC today to speak at a congressional briefing on safe and supportive school environments and particularly to underscore the research on how recent immigration raids are influencing students and schools.
In the last school year, after years of controversy, San Francisco schools fielded pilots that reintroduced Algebra to 8th grade. A preregistered, quasi-experimental study by Elizabeth Huffaker and me indicates the major pilots were largely successful. www.nytimes.com/2026/03/24/u...

I spoke with The Minnesota Star Tribune about the research evidence, mine and others, which indicates the many ways in which aggressive immigration enforcement harms children, schools, and communities. www.startribune.com/coronavirus-...
Perry: The learning loss from the ‘ICE pandemic’
"As Trump’s virus lurked around Minnesota schools looking to kidnap children and their parents, many children quite reasonably went into hiding," David M. Perry writes.

For context, this drop in attendance rates related to the measles outbreak (about 93% to 90%) is almost as large as the initial drop in TX attendance rates from pre-pandemic to post-pandemic (95% in 2018-19 to 91% in 2021-22). (TX attendance trends over time here: www.aei.org/research-pro...)
We provide early evidence on the impact of vaccine-preventable disease outbreaks on learning opportunities, and the schooling disruptions that the growing number of low-coverage communities could face if outbreaks continue to spread. See working paper: edworkingpapers.com/ai25-1358
In 2000, measles was declared eradicated in the U.S. Today, declining child-vaccination rates are driving the largest measles resurgence we've seen in 3+ decades. How do these outbreaks impact schooling? @tomdee.bsky.social and I examine this question in West Texas, the country's largest outbreak.
Our preregistered study of mental-health co-responders—now out in Nature Human Behaviour (doi.org/10.1038/s415...) —finds positive benefits in terms of significant reductions in psychiatric detentions and future mental-health crises relative to police-only responses.
The aggressive immigration raids we now see across the nation began 10 months ago in California's Central Valley. Their impact on children, families, and communities is an important & active area of research I'm pleased my study of the initial raid's early impact on students is now out in @pnas.org
Empirical evidence and conceptual reasoning suggest quasi-experimental studies—the most common form of studies making causal claims—have a "p-hacking" problem. My essay on this and the case for adapting & adopting QED preregistration is now published in Evaluation Review. doi.org/10.1177/0193...

Have we given too much "credit" to the pandemic for learning losses? Almost 50% of the post-pandemic decline in achievement on 8th grade NAEP was to be expected (without the pandemic!), simply using the same rate of declining achievement that began unfolding starting in 2013!
This provocative, data-infused essay by James Wyckoff — edworkingpapers.com/ai25-1197 — serves as a reminder that fully understanding the declines in student achievement requires us to look well before the COVID-19 pandemic.
