Summary

Sanborn Elementary School is a public elementary school serving grades PK-5 in Longmont, Colorado, part of the St. Vrain Valley School District, which is ranked 27th out of 115 districts in the state. With 239 students, Sanborn Elementary faces significant challenges compared to other schools in the district.

Academically, Sanborn Elementary consistently underperforms, with proficiency rates in 2024-2025 of 42.9% in ELA and 33.7% in Math, compared to the district's 50.9% and 45.4%, and the state's 44.8% and 35.9%. This trend has persisted over the past several years. The school also struggles with high chronic absenteeism, reaching 27.7% in 2023-2024, significantly higher than the state average. As a result, Sanborn Elementary has consistently ranked in the bottom half of Colorado elementary schools, receiving a 2-star rating from SchoolDigger.

In comparison, other schools in the district, such as Hygiene Elementary (ranked 32nd in the state) and Central Elementary (ranked 45th), have much higher academic proficiency rates and lower chronic absenteeism. The high percentage of students from low-income families at Sanborn, coupled with the high chronic absenteeism rates, may be contributing to the school's academic struggles. Targeted interventions and support for these students could be crucial in improving Sanborn's performance and outcomes.

Worst school, if your child has health issues be prepared to have to deal with one of the worst district nurses, as well as this school will put policies over your child's mental health and education. Both my children are behind due to the negligence of this school. I would not enroll your children here. Close Quote

Underperforms in every category across all levels and the teachers blame the parents for any issues with the students despite never handing out homework. My daughter has come home confused multiple times regarding reading, writing, and maths, requiring me to re-educate her over several hours to correct their curriculum and teaching breakdown. A lot of young teachers without adequate teaching experience. Close Quote
