The Dear Colleague Letter’s Real Argument: Evidence in Education Is a Shared Responsibility

On August 20, 2026, the U.S. Department of Education’s Office of Elementary and Secondary Education released a Dear Colleague letter on education technology and screen time in schools, signed by Assistant Secretary Kirsten Baesler. On the surface, it reads like a response to a familiar anxiety: parents worried about how much time their kids spend looking at a screen, districts caught between innovation and backlash, headlines that treat “edtech” and “screen time” as the same problem.

But underneath that framing is a much sharper argument, and one that matters a great deal to anyone building or buying educational technology: the Department is telling states, districts, and vendors that the question was never really about screens. It was about evidence.

What Distinction Does the Letter Draw Between Recreational and Instructional Technology?

The letter is explicit that recreational technology and instructional technology should not be evaluated by the same yardstick. A student scrolling on a phone after school and a student using a diagnostic assessment tool that gives a teacher real-time information about a reading gap are not the same use of a screen, even though both involve one. As the letter puts it, the question districts should be asking is not whether teachers and students use technology, but whether the specific technology they’re using improves learning and academic outcomes.

That reframing does real work. It gives district leaders language to defend genuinely useful tools against blanket screen-time policy, while still giving them permission to be skeptical of tools that can’t demonstrate value. It also puts the burden of proof back where it belongs: on the product, not the device.

“We know how damaging screens are, but we put middle schoolers and high schoolers in front of Chromebooks all day long… I think we should be implementing policies based on research that we know can enhance learning and wellbeing.”

It’s worth saying plainly that the underlying concern the letter is responding to is a legitimate one. That sentiment isn’t in tension with the Department’s letter — it’s the exact tension the letter is trying to resolve. Educators aren’t anti-technology. They’re asking for the same thing the Department is now asking for: proof that a given tool is worth the screen time it asks for.

Where Does ESSA Fit Into the Letter?

The letter doesn’t introduce a new evidence standard. It points directly at an existing one. It calls out the Elementary and Secondary Education Act, as amended by the Every Student Succeeds Act, as reflecting a longstanding federal commitment to evidence-based decision-making, and it tells states and districts to draw on that established framework as they make procurement and implementation decisions.

That’s a meaningful signal for anyone who has watched ESSA’s evidence tiers — what those tiers actually require and why they matter — treated as a nice-to-have rather than a procurement requirement.

The letter also draws a direct line to Secretary Linda McMahon’s earlier Dear Colleague letter on AI in education, which laid out five principles for responsible use — educator-led, ethical, accessible, transparent, and protective of student data. This new letter is careful to say those principles are the floor, not the ceiling: responsible design doesn’t by itself prove educational value. A product can be perfectly ethical and transparent and still not move outcomes.

The Department’s language here is worth sitting with — it wants to know not just if a tool works, but why it works, for whom, and under what conditions. That is, almost word for word, the logic of the ESSA evidence tiers.

What Is the Department Asking of Edtech Vendors?

The most concrete section of the letter is a short list of expectations for education technology providers. States and districts, it says, should expect vendors to publish rigorous, independent evaluations of product impact whenever feasible; share implementation guidance grounded in effective classroom practice; be transparent about capabilities and limitations; and continuously improve products using evidence from real classrooms.

None of that is abstract. It’s a checklist, and it maps almost exactly onto the case LXD Research has been making to edtech companies for years: a vendor claim is not evidence, and a demo is not a study. The letter even flags procurement experiments already underway in Louisiana, Arkansas, Indiana, Michigan, and Texas that build shared performance measures and outcome expectations directly into vendor contracts — the same outcomes-based contracting model where districts hold back a meaningful share of payment until agreed student results show up. Those models started with tutoring services and are now extending into edtech more broadly — a preview of where evaluation criteria are headed for every state watching those pilots.

For a founder or product leader reading this letter, the practical takeaway is straightforward: the market is moving toward requiring exactly the kind of third-party, ESSA-aligned evidence that used to be a differentiator and is becoming table stakes. As we noted in a recent look at the state of the edtech market, most products still don’t have that evidence in place — which means the letter is less a warning to well-documented products and more an early-mover advantage for the companies that build the evidence base now, ahead of the requirement.

Why Does the Letter Call Evidence-Building a Shared Responsibility?

The letter closes on a point that’s easy to skim past but shouldn’t be: it frames evidence-building as a shared responsibility across states, districts, educators, families, researchers, and providers, not something any one group can solve alone. Districts can’t procure their way to good outcomes if no vendor can produce credible evidence. Vendors can’t produce credible evidence without educators and researchers willing to test claims transparently. And none of it works if the standard for “evidence” is left vague enough that any white paper counts.

That’s the gap independent, ESSA-aligned research is built to close — turning “we believe this works” into a study a district’s procurement team can actually stand behind.

If you’re a product leader trying to figure out where your evidence currently stands, or a district administrator trying to evaluate a vendor’s claims against this new guidance, that’s exactly the conversation worth having now, while the field is still figuring out what “meeting the standard” will mean in practice.
