Bibb Hubbard, founder and CEO of Learning Heroes, joins the Education Gadfly Show to discuss grade inflation and the disconnect between what parents think report cards are telling them and how students are actually performing. As families rely on grades and teacher feedback to understand student progress, can stronger school-family communication help give parents a more honest picture of how their children are doing?

Then on the Research Minute, Amber Northern looks at new research on Chicago’s merit-based free community college program and what it suggests about college choice, degree attainment, and whether free tuition at two-year colleges steers students away from four-year success.

Mike Petrilli takes a solo turn to tackle teacher diversity, a topic at the center of today’s debates over DEI. Should schools recruit teachers whose backgrounds reflect those of their students? What does the research say about how shared life experiences shape student outcomes? And how can schools promote diversity while maintaining high standards for academic excellence?

Then on the Research Minute, Amber Northern examines new research on Arkansas’s LEARNS Act, which raised the state’s minimum teacher salary to $50,000, and what it reveals about teacher pay and retention.

Drew Bailey, professor at the University of California, Irvine, joins The Education Gadfly Show to discuss the fadeout effect across education interventions. Why do early treatment effects shrink over time, and what does that mean for judging program success, especially when test score gains diminish but long-term outcomes like graduation rates and earnings persist? We also debate the role of test scores in accountability, the evidence linking school value-added to real-world success, and what this all means for the role of testing in school choice initiatives.

Then on the Research Minute, Amber Northern examines new data on how states define “proficiency” in reading and math and what NAEP reveals about rigor, transparency, and the debate over standards.

Karen Vaites, founder of The Curriculum Insight Project, joins us to discuss the evolving debate over curriculum reviews and state adoption policies. As more states look to third-party evaluations to guide decisions—and some consider mandating state-approved lists—how can policymakers avoid making costly mistakes?

Then on the Research Minute, Amber Northern examines new evidence on whether teacher effectiveness truly transfers when high-performing educators move into lower-achieving schools.

This week on The Education Gadfly Show, Mike Petrilli goes solo to talk about grade inflation—what it means, how it’s changed over time, and why tougher grading standards help students learn more. He argues that easier grades don’t serve students well—and explores what states can do about it.

Then, on the Research Minute, Amber Northern shares new evidence from Texas showing that distance from public colleges—especially community colleges—strongly shapes whether students enroll in and complete college, with particularly stark effects for lower-income and Hispanic students.

This week on The Education Gadfly Show, we’re joined by Elliot Regenstein, partner at Foresight Law + Policy and author of Readiness: Preparing State Early Childhood Systems for a Brighter Future, to talk about early childhood education and care—and why state systems are so often fragmented and hard to navigate. We discuss who makes key decisions, why coordination is so difficult, and what it would take to build more coherent early childhood systems going forward.

Then, on the Research Minute, Amber Northern shares new evidence on achievement gaps across different types of schools, showing that inequality has grown fastest in traditional public schools, while charter schools show more positive trends over time.

We explore a deceptively simple question: Why don’t educators, policymakers, and researchers spend more time studying success?

Then, on the Research Minute, Amber Northern highlights new evidence from New York City showing that small public high schools significantly boost graduation rates and college enrollment, especially for disadvantaged students.

This week on The Education Gadfly Show, we’re marking National School Choice Week with a conversation with Shelby Doyle of the National School Choice Awareness Foundation.
