Minnesota Department of Education

MDE is the state agency responsible for overseeing public K‑12 education in Minnesota. It develops and implements academic standards that guide curriculum and instruction across school districts. The department administers the Minnesota Comprehensive Assessments (MCA), a series of standardized tests used to measure student proficiency in subjects such as reading, mathematics, and science. In addition to testing, MDE provides technical assistance, funding oversight, and professional development resources to educators and administrators. It also collects and reports educational data to inform policy decisions and public accountability.

MDE's role places it at the intersection of education policy and assessment administration, making it a central authority for ensuring compliance with state and federal education requirements. The agency has experienced several notable incidents that highlight its reliance on third‑party technology platforms, including a 2023 data breach involving the MOVEit file transfer service that exposed personal information of approximately 95,000 students across 24 files. Earlier, in 2015, a distributed denial of service attack on the testing vendor Pearson disrupted online MCA administrations for weeks, leading to temporary suspensions of statewide testing. That same year, a computer system failure during MCA testing forced the department to halt all assessments statewide while technical issues were resolved. These events underscore the department’s critical function in delivering statewide assessments and its vulnerability to cyber and operational disruptions.
