Summary:

Zip code 58845 has two schools in the Grenora 99 district: Grenora Elementary School, serving PK–6, and Grenora High School, serving grades 7–12; each enrolls 83 students, for 166 combined. The clearest concern across the schools is math: their 2024–2025 average was 32% proficient, 9 percentage points below the state’s 41%, and their latest reported combined range remains below the state.

The schools’ strongest results differ by subject. In 2024–2025, Grenora Elementary School led in math with 44% proficient, compared with 20% at Grenora High School—a 24-point gap; Elementary was 3 points above the state, while High was 21 points below. High stood out in science at 45%, versus Elementary’s 39%, and was 7 points above the state. Reading was nearly even: High had 45% and Elementary 44%, with both above the state’s 40%. The latest two-school math average is reported as 35–53.5%, compared with a state result of 54%; even the range’s upper end is 0.5 point below the state.

SchoolDigger’s latest rankings favor High, while the schools’ rank histories moved differently: Elementary went from the 35th percentile in 2023–2024 to the 58th and then the 19th, while High rose from the 42nd to the 58th percentile and stayed there; in 2025–2026, SchoolDigger ranked Elementary 174th of 216 (19th percentile, 1 star) and High 54th of 129 (58th percentile, 3 stars). Test-score ranges for 2025–2026 are too broad to establish clear year-to-year changes, though Elementary math was 44% in 2024–2025 and is now reported as 40–48%, while High moved from 20% to a reported 30–59%. As context, both schools reported 19% free/reduced lunch eligible in 2024–2025; student-teacher ratios were 8.3 at Elementary and 10.2 at High.

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.
