Top rankedPotrero Elementary5789^th of 5,857 California elementary schools

Summary:

Zip code 91963, covering the rural Potrero area near the California-Mexico border, contains one elementary school, Potrero Elementary, which serves grades K-6 within the Mountain Empire Unified school district.

Parents should be aware that Potrero Elementary faces significant academic challenges, consistently ranking in the bottom 1-2% of all California elementary schools. Proficiency rates in English, math, and science are substantially below both state and district averages, with mathematics performance being a particular area of concern. The school also reports a very high rate of chronic absenteeism, more than double the state average, which is a critical factor affecting student learning.

Despite these academic struggles, the school operates with a high level of per-student spending. The student population has a high level of economic need, which often correlates with additional educational challenges. The school's performance reflects broader difficulties within the Mountain Empire Unified district, which itself ranks in the lower percentiles statewide, indicating that families in this isolated area are navigating a complex educational landscape.
