North Dakota Academic Progression of Learning and Understanding of Students or ND A-PLUS (ND A+) is a new, connected system of assessments that includes state-provided formative assessments (called Navvy), interim assessments, and a statewide summative assessment. The North Dakota Content Standards serve as the foundation for the entire ND A+ assessment system, with all three of the assessments strongly aligned to the ND educational content standards. The assessments within the system, each with a unique use and purpose, connect together to provide multiple pieces of evidence and support educators, schools, and districts in creating a more coherent, comprehensive story of student learning. Window for assessments open March 17th and close May 9th.
