The em dash with spaces around it feels like a clue…

This is the D.A.R.E. Program for sports gambling 😭

Really interesting piece. While a fair number of ed policy folks have tossed around the idea of bringing back ed reform, I don’t see the political will for a project like this at the moment. Something - perhaps not unlike A Nation at Risk - will need to happen first

God Virginia rocks

That was a shellacking 😮‍💨

Np! I spread the Jim Wyckoff good word whenever possible

Table from a study of teacher transfers in New York City (1993–1998) comparing characteristics of “sending” vs. “receiving” schools. Columns show within-district and between-district moves, each with sending school, receiving school, and the difference. Within districts, differences are small (e.g., slightly lower poverty and nonwhite share in receiving schools, minimal class size change). Between districts, differences are large: teachers move to schools with far lower poverty (−0.468), fewer nonwhite students (−0.482), fewer English learners (−0.091), smaller class sizes (about 5.8 fewer students), and higher salaries (about $4k–$7k more). Most between-district differences are statistically significant.

I think Lankford et al. (2002) has some really strong descriptive tables: journals.sagepub.com/doi/10.3102/...

I find the one below really powerful: Teachers who switch schools within a district tend to move to similar schools, while those who switch districts move to more advantaged schools

Extreme emphasis on internal validity strikes me as the most plausible explanation

These results are robust to coding errors I made the first time around

Amen - folks put a lot of weight on the results from some elite institutions that surely had little variation in GPA across matriculates

Had been waiting for evidence from a network of public universities on the High School GPA versus SAT scores debate. Credit to the authors Joyce, Khosroshahi, Truelsch, Gentsch, and Du.

what if, rather than approximate answers to the right questions, we got exact answers to the wrong question, made ever more precise, more quickly?

@brhkim.bsky.social surely has thoughts here!

Thanks to those who came out! It was a great #AEFP2026

Professors & university staff were targeted & fired for less than this just a few months ago.

The worst part of AEFP is not being able to see all the great work (and great people) that's presented there.

Looking forward to next year!

🚨 Hey You! 🚨

Still at #AEFP tomorrow? Come check out my presentation at 11:45 AM in Vevey 2, where I’ll present some extremely hot off the press work on a statewide teacher compensation policy in Texas

They know what we need 🤣

I’ve decided I’m running the unofficial #AEFP 2026 Free Pen Competition. Please provide any thoughts below—although I have appointed myself the ultimate arbitrator

Check out the encore too! 🎶

stop spending money on Claude Code; Chipotle’s support bot is free

I’m gonna scream this one from the rooftops

The way a lot of the "stop asking schools to fix broader social problems" crowd has backed themselves into "districts should build housing and become landlords" is kind of bananas.

Congrats on the working paper!

Thank you!

Would be very eager to read a working paper copy of this! Seems super interesting

Great thread—and accountability done by @jenjennings.bsky.social !
