This document discusses who provides student data to edtech vendors. Teachers provide data through curriculum tools and gradebooks, while school districts work with vendors like eScholar and Knewton. Parents provide data through apps and Google Apps. It also addresses where vendors store student data in operational, backup, and redundant systems, and what happens to the data when policies change, if the vendor is sold or declares bankruptcy. The document encourages asking vendors questions and offers coaching on edtech and data-driven instruction.
