On August 20, 2026, the U.S. Department of Education released a Dear Colleague Letter signed by Assistant Secretary of Elementary and Secondary Education Kirsten Baesler that asks schools and districts to evaluate educational technology by its demonstrated impact on learning rather than by the amount of time students spend on screens. The letter does not carry the force of law, but it marks the first time the agency has weighed in on the K-12 screen time debate at a moment when at least six states have enacted laws restricting classroom digital instruction, according to multiple news outlets.
Baesler wrote that recreational technology and education technology should not be treated as the same thing. The letter acknowledges concerns about excessive recreational screen use but argues that well-designed ed tech can strengthen teaching and deepen learning when it is aligned with clear instructional goals and implemented effectively. The guidance directs states and districts to distinguish between policies meant for recreational technology and those that govern instructional technology, to evaluate ed tech based on learning outcomes rather than screen time alone, and to use evidence of effectiveness in procurement and renewal decisions.
Five questions for every product
The letter poses five questions it says every ed tech product should satisfy: what learning problem does it solve, when should it be used, for whom should it be used, for how long should it be used, and what evidence shows that it improves student learning. The letter also asks ed tech providers to publish rigorous, independent evaluations of their products' impact on student learning, to share implementation guidance rooted in classroom practice, to disclose capabilities and limitations, and to continuously improve products based on implementation and student outcome data.
State screen-time caps create tension
The federal approach of quality over quantity sits in potential conflict with state laws passed in 2026 that impose hard daily limits on instructional screen time. Iowa's HF 2676, signed May 20, caps digital instruction at 60 minutes per day for kindergarten through fifth grade, with exceptions for special education plans, assessments, and computer science. Tennessee's HB 2393/SB 2310 requires K-5 districts to adopt policies that minimize student device use and prioritize teacher-led instruction, and it bans social media on school internet for those grades. Utah's HB 273 prohibits screen time in grades K-3 except for computer science and assessment preparation.
Alabama's HB 78, the Healthy Early Development and Screen Time Act, requires state agencies to set evidence-based screen time standards for pre-K, licensed child care, and kindergarten, and bans screen time for children under 2. Virginia's SB 568 directs the state education department to develop model policies limiting instructional screen time by grade level and requires schools to teach students about the addictive potential of devices. Maine took a different approach with LD 2052, commissioning a study of classroom technology use rather than imposing a hard cap. A Minnesota law enacted in 2021 already prohibits children in publicly funded preschool or kindergarten from using individual-use screens without active teacher or peer engagement.
The Los Angeles Unified School District, the second-largest district in the country, voted 6-0 in April 2026 to adopt systemwide grade-by-grade instructional screen time limits. The policy bars instructional screen time before second grade and sets incremental limits for older students.
Outcomes-based contracting gets a nod
The Dear Colleague Letter praised Arkansas, Indiana, Louisiana, Michigan, and Texas for exploring contracting models that tie vendor payments to performance measures rather than to product adoption or usage metrics. Baesler wrote that early research suggests the approach holds promise, though the letter does not cite specific studies. The letter describes outcomes-based contracting as an emerging practice rather than an established evidence base.
What the research says about screen time and learning
An OECD policy paper based on PISA 2022 data found that moderate digital leisure use outside school, between two and four hours per day, was associated with higher math scores than very low or very high use. More than four hours per day was linked to lower math performance and a lower sense of belonging. At school, even one hour of digital leisure was associated with math scores about 9 points lower. The paper notes that it does not establish causality and focuses on leisure use rather than instructional technology. The finding partially supports the federal letter's distinction between recreational and educational screen time.
A research synthesis from ISTE+ASCD concluded that well-designed educational technology built in accordance with how people learn offers distinct academic advantages, citing studies by Feng (2025) and Hillmayr et al. (2020). Poorly built ed tech, the synthesis found, adds unnecessary cognitive load and inhibits learning, citing Støle et al. (2020). The synthesis also found that ed tech is particularly impactful for underserved students, including those with disabilities, multilingual learners, and students below grade level. It argues that research on social media or consumer entertainment tools does not necessarily apply to educational tools.
A policy frame, not a mandate
Baesler wrote that decisions about digital learning tools are best made by states and local communities with input from parents and teachers. The letter is described as guidance and a synthesis of research, not federal enforcement. It follows a July 2025 letter from Secretary of Education Linda McMahon outlining five principles for responsible AI use in education.
