Cornerstone Montessori Elementary

Summary:

Cornerstone Montessori Elementary is the sole public charter elementary school serving grades K-6 in Saint Paul, Minnesota, with a total enrollment of 138 students. While the school's small size and unique charter status set it apart, its academic performance has seen a steady decline in recent years, with proficiency rates on standardized tests falling below the state averages.

Despite serving a high-poverty student population, with over 56% of students qualifying for free or reduced-price lunch, Cornerstone Montessori Elementary has struggled to maintain its statewide ranking, dropping from 392 out of 845 Minnesota elementary schools in 2022-2023 to 606 out of 872 in 2024-2025. The school's proficiency rates on the MCA-III math and reading assessments are significantly below the state averages, with math proficiency ranging from 11-31% and reading proficiency from 16-66% across different grade levels.

While the reasons behind the school's academic challenges are not entirely clear from the data provided, the high poverty rate and small school size may be contributing factors. Further investigation would be needed to fully understand the root causes and potential solutions to improve the outcomes for students at Cornerstone Montessori Elementary.
