Strata puts classroom walkthroughs, feedback, and coaching in the pocket of every school leader and teacher. Walk into a classroom with your iPhone, tap a teacher, and see a 30-second briefing of where they stand. Run through your district's look-fors with quick-tap scoring and voice-dictated evidence notes β transcribed on device, so you keep watching the room. Tap once to generate a feedback draft in the Evidence / Interpretation / Next-step format, review it, and deliver. The teacher gets a notification, reads the feedback, and submits a reflection β without ever opening a laptop. FOR SCHOOL LEADERS - Quick-tap look-for scoring sized for one-handed, in-classroom use - Voice-to-text evidence notes, transcribed on device - AI walkthrough prep briefings drawn from each teacher's history - Generate feedback drafts in seconds and deliver in a tap FOR TEACHERS - A clean inbox of feedback with the full Evidence / Interpretation / Next-step view - Structured, voice-friendly reflections you can submit from anywhere - A personal growth timeline showing your progress over time WORKS OFFLINE Classrooms have spotty Wi-Fi. Strata captures everything locally first and syncs in the background the moment you reconnect β a dropped connection mid-walkthrough costs you nothing. ASK STRATA Ask questions about your data in plain language β "Which teachers haven't been visited this month?" β and get answers scoped to your role. Strata is built for districts running instructional walkthrough and coaching programs. A Strata account from your district or school is required to sign in.
