- Reposted by Thomas S. DeeFor 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
- Reposted by Thomas S. DeeIn 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
- Open access is available here: doi.org/10.1073/pnas....
- 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...
- Such a warm, engaging, and informative visit! My thanks to the @annenberginstitute.bsky.social at Brown University for inviting me to give the Annenberg 2025 Distinguished Lecture.
- I'm honored to give the Annenberg 2025 Distinguished Lecture next week and looking forward to being in conversation with this outstanding community.
- Know any aspiring PhD students interested in quant studies in education? Please direct them to our programs in ed policy, econ of ed, or ed data science! I hope to welcome an energetic & ambitious student to join me in our new building 🌴☀️ Applications due November 17 ed.stanford.edu/admissions/a...
- 🚨Do you know a school, system, or network doing amazing work in support of student success in high school, particularly through a continuous-improvement approach? Let's recognize them! Encourage them to apply for the Carnegie Award for Impact (cfdn.at/4o4gp58). Applications due on November 10.

- Reposted by Thomas S. DeeThe @nytimes.com spotlighted a new study from #EdWorkingPapers that examines the profound impact of immigration raids on attendance in California's Central Valley. Read the NYT article below.
- The current wave of federal immigration raids began in January with a “rogue” operation in California’s Central Valley. My new study finds these raids increased school absences by 22%—a leading indicator of the resulting family stress & lost learning opportunities👇 www.nytimes.com/2025/06/16/u...

- 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.

- I was so pleased to cross the Bay today and speak at the Berkeley Initiative for Transparency in the Social Sciences (www.bitss.org) about the need for (and feasibility of) adopting preregistration of studies making causal claims with observational data. #OpenScience

- Need some good education news? Over the last decade, the number of students taking an AP Computer Science exam more than tripled and that was no accident. In a new @pnas.org study, Daniela Ganelin & I find that roughly two-thirds of this growth can be attributed to the new AP CS Principles course.
- Furthermore, this new course didn't crowd out take-up of the incumbent AP CS A course. Instead, it diversified the students in AP Computer Science and it may have even encouraged the take-up of other AP courses. Open access @ www.pnas.org/doi/10.1073/...

- I just shared this "continuous improvement" toolkit with someone who approached me about how to drive positive change in their school district. This useful product, which is from a recently cancelled Regional Educational Laboratory, is an example of what this Administration is defunding.

- Today's NAEP results—& the apparent role of chronic absenteeism—are unsurprising to any close observer What's curious to me is this evidence-based sense of calamity doesn't really shape broader public sentiment. In fact, satisfaction is rebounding!👇 Is it crisis fatigue? Biases in info & judgment?

[Not loaded yet] - Interesting dive into the stunning, latest math assessments. This heterogeneity in the US math score declines (e.g., by gender, grade, achievement level) doesn't easily comport with dismissive narratives that suggest it's simply a post-pandemic decline in test effort.
- I appreciate this cogent summary of our study of the Algebra I Initiative (i.e., targeted acceleration + supports for instructional differentiation). And I share concerns that a replication and scale-up are not necessarily straightforward. #EduSky But... fordhaminstitute.org/national/com...
