Summary:
This analysis examines eight elementary schools serving grades K-6 in zip code 91763 (Montclair, CA), all part of the Ontario-Montclair School District, revealing significant differences in performance despite similar economic challenges and district oversight.
Among these schools, Monte Vista Elementary and Buena Vista Arts-Integrated stand out as top performers with 4-star ratings, boasting the highest test scores and remarkably low chronic absenteeism under 2.5%. In contrast, Lehigh Elementary and Kingsley Elementary have consistently lower rankings and proficiency rates, particularly in math and science. The remaining schools, including Montera Elementary, Ramona Elementary, Howard Elementary, and Moreno Elementary, show mid-range performance with 2 or 3-star ratings.
Key insights show a strong link between low chronic absenteeism and higher academic achievement, while per-student spending does not directly correlate with performance. Science is the weakest subject area across most schools. The consistent performance trends over several years suggest these are established patterns, indicating that higher-performing schools could serve as models for effective practices within the district, such as maintaining high attendance and implementing specialized programs like arts integration.
