Summary:
Academia Antonia Alonso is a single K-8 charter school in Newark, Delaware, serving 910 students and operating as its own district, which means the school and district data are identical.
This school faces significant academic challenges, consistently ranking in the bottom 10% of Delaware schools. Its state percentile ranking actually declined from the 9th percentile in 2024-2025 to the 7th percentile in 2025-2026, and it received zero stars in two of the past three years. Proficiency rates trail state averages by 15 to 27 percentage points across all subjects and grade levels. Mathematics is a particular weakness, with proficiency dropping as low as 7.61% in 6th grade, compared to a state average of 31.26%. English Language Arts performance is somewhat stronger but still lags significantly, with 3rd grade proficiency at just 14.74% versus the state's 40.05%. The school's strongest subject-area showing is 7th grade Social Studies at 49.04% proficiency, coming within 10.81 points of the state average.
There are some encouraging signs amid the overall struggles. Fifth grade ELA improved dramatically by 10.85 percentage points year-over-year, rising from 17.24% to 28.09%, and 4th grade math improved by 8.03 points. The school's chronic absenteeism rate of 15.1% is actually better than the state average of 17.1%, suggesting attendance is not the primary driver of low performance. With a student-teacher ratio of 18.2:1 and per-student spending of $13,286, the school has moderate resources, but the persistent underperformance raises questions about how effectively those resources are being allocated. The declining overall ranking despite some grade-level improvements indicates that other Delaware schools are improving at a faster pace, and more comprehensive, systemic interventions will be needed to change the school's academic trajectory.
