This year, four states passed laws restricting or regulating screen time for students from childcare through fifth grade. A new Tennessee law requires every district and charter school serving K-5 students to adopt an age-appropriate digital device policy to minimize unnecessary screen time. The district also set limits that increase incrementally to 60 minutes per subject each week for middle school students and 90 minutes per subject each week for high school students. Tracy Weeks, senior director of education policy and strategy at education technology company Instructure, told Stateline that states should consider metrics other than minutes when proposing screen time policies. Maine is directing the Maine Education Policy Research Institute to study classroom technology use, including average instructional time on school-issued devices and existing safeguards.
