Privacy Enhancing Technologies for State Education Agencies

This report describes the Privacy-Enhancing Technologies (PETs) most relevant to State Education Agencies (SEAs) and Statewide Longitudinal Data Systems (SLDS) environments, explains what each can and cannot do analytically and operationally, and provides use case guidance for matching PET selection to specific workflows. PETs complement rather than replace strong governance — data minimization, least-privilege access, auditing, and enforceable agreements. The goal is a meaningfully smaller exposure surface, better-controlled outputs, and analytical workflows that agencies can stand behind.
