ClassLink

ClassLink — The largest single view of what students actually do on school-owned devices. ClassLink's SSO layer authenticates roughly 25 million students and staff into 6,000+ apps across 3,000+ school systems, and its Analytics+ tier captures domain-level records for every website accessed on a school-owned device — including resources launched outside ClassLink — as sessions with app, domain, date, time and minutes-used, rolled up to district, school, grade, classroom and individual student. Around it sit three derived assets: Screen Time, which classifies device time into district-selected…

ClassLink offers (Alternative, Fundamental, Sentiment) — Est. tens of billions of session/domain events per year. Basis: ~25M users x ~180 school days x tens of domain hits per user per day easily exceeds 10 billion rows; the nearest published comparable in this category (a competitor's report over 3.7M students in one year) counted 64 billion interactions, implying a per-student rate that at ClassLink's installed base scales well past that. The Screen Time layer additionally stores minute-level, category-labelled device time — the highest-fidelity component..

Demand-side edtech market intelligence at a scale nothing else reaches (which of 6,000+ tools are actually used, by which grades and subgroups, for how long, and at what price — the ground truth behind renewals); attention and engagement sequence data for modelling focused versus fragmented digital attention in children; education-technology vendor lead-scoring and churn prediction (underutilised licences identify at-risk contracts); equity-of-access research joined to demographics; device and browser telemetry; generative-AI adoption measurement in schools, which the vendor explicitly calls out as a use; and — uniquely — paired usage-and-assessment-gain data for tool-effectiveness research and for training models that predict learning outcomes from interaction patterns.

The data is with 14 years of history.
