Summary

Edison (Thomas A.) Charter School is a K-8 charter school in Wilmington, DE, serving 557 students and operating as its own district, which currently ranks last among Delaware's 34 districts.

This school faces significant academic challenges, particularly in mathematics and early literacy. Statewide, Edison consistently ranks in the bottom 1st percentile of elementary schools, placing it well below nearby charter schools like East Side Charter School and Kuumba Academy Charter School. Math proficiency is critically low across all grades—for example, only about 7% of 4th graders and 12% of 7th graders met state standards, compared to state averages of 40% and 32%, respectively. Early reading is also a struggle, with just 13% of 3rd graders proficient in ELA. However, there's a notable bright spot: the school shows a "reverse bell curve" in English Language Arts, meaning performance improves as students get older. By 8th grade, ELA proficiency has reached 19% in recent years, and in prior years it actually surpassed the state average—hitting 49% in 2022-2023 and 47% in 2023-2024. This suggests the middle school ELA program may be doing something right that could be replicated in other subjects.

The most striking positive finding is the dramatic improvement in chronic absenteeism. It has plummeted from a staggering 41.5% in 2020-2021 to just 2.5% in 2024-2025—now far better than the state average of 17.1% and better than all nearby schools, including the high-performing First State Montessori Academy (5.0%). This suggests a major recent shift in school culture and engagement. However, this attendance improvement hasn't yet translated into higher test scores, indicating that instructional quality and student support may be the primary drivers of low performance. For parents considering this school, the picture is mixed: severe math challenges and early literacy gaps persist, but the upper-grade ELA success and remarkable attendance turnaround offer glimmers of hope worth investigating.
