What this is
District-level expectations and guidance for how much, when, and for what purposes students use screens — differentiated by grade band and by subject, with attention to quality (what is on the screen) and not just quantity (how much time).
Why it matters
Screen time isn't homogeneous — thirty minutes of deep reading is not the same as thirty minutes of TikTok. The most useful screen-time norms attend to what students are doing on the screen and what learning it serves, not just minutes.
Connects to
The Framework: Cognitive & Ethical Foundation — Sustained Attention; Condition #11 (Cognitive Counterweights).
Maturity levels
Not Started
No norms or guidance. Screen time determined by whichever curriculum or tool is adopted. No reflection on quantity or quality.
Emerging
General statements about "appropriate screen time" but no specifics. No grade-band or subject differentiation. No accountability or reflection built into curriculum adoption decisions.
Established
Written screen time norms differentiated by grade band (K-2, 3-5, 6-8, 9-12) and by subject (some subjects appropriately more screen-heavy than others). Addresses both quantity and quality — active vs. passive, creative vs. consumptive, connected to learning goals vs. default delivery mode. Integrated into curriculum review cycles.
Expanding
Norms are evidence-informed, reviewed annually, and tied to cognitive development research (including early literacy, sustained attention, working memory). Teachers have frameworks for when screens genuinely add value and when they do not. Student and family-facing guidance available. Tracked against outcomes, not just inputs. Adjusted in response to research and student data.
