IMPORTANT NOTE: North Dakota does not publish exact assessment percentages; instead, results are reported as ranges (e.g., 20-29%) to protect student privacy in smaller groups. The proficiency rates displayed on SchoolDigger are calculated using midpoint imputation—the center value of each reported range. Actual values may differ by up to 5 percentage points from the figures shown.

About North Dakota Assessment Data: To protect student privacy, the North Dakota Department of Public Instruction reports assessment results as percentage ranges rather than exact values. SchoolDigger calculates proficiency rates using midpoint imputation, which uses the center value of each reported range. For example, a reported range of 20-29% is represented as 24.5%. As a result, the proficiency rates shown may vary by approximately ±5 percentage points from actual values. This variance is most significant for individual grade/subject combinations and diminishes when data is aggregated across multiple grades or subjects.

IMPORTANT DISCLAIMERS: Not all boundaries are included. We make every effort to ensure that boundaries are up-to-date. But it's important to note that these are approximations and are for general informational purposes only. To verify legal descriptions of boundaries or school locations, contact your local tax assessor's office and/or school district.
