Montana's six required statewide assessments are delivered to students mostly via online solutions. The Office of Public Instruction (OPI) contracts with test delivery contractors in order to deliver these assessments to students enrolled in Montana accredited schools. School districts must manage educator training, student rosters, student delivery, and achievement reporting through these various online portals. Each assessment is managed independently from one another as the assessments themselves have different purposes and measurement intentions. System Test Coordinators should ensure proper school district policies for managing local users and permissions to the online Test Delivery System (TDS) portals listed below.
