Summary:
Zip code 19805 in Wilmington, Delaware is served by five schools—three elementary schools (including one early education center) and two alternative schools—spanning grades PK through 12, with a total enrollment of about 3,618 students across the Odyssey Charter School, Christina School District, and Red Clay Consolidated School District.
The clear standout is Odyssey Charter School, a K-12 charter enrolling 2,286 students (63% of the zip code’s total). It posts a chronic absenteeism rate of just 7.9%—less than half the state average—and beats state proficiency averages in nearly every subject and grade, with 5th grade social studies at 74.6% versus the state’s 61.9%. By contrast, The Bayard School (K-8, 571 students) ranks in the bottom 3% of Delaware schools, with ELA proficiency below 13% at every grade level and chronic absenteeism at 27.5%. Baltz (Austin D.) Elementary School sits in the middle, with 3rd grade math at 26.9% versus the state’s 42.7%. Douglass School, an alternative program for grades 1-12, faces the steepest challenges with 68.1% chronic absenteeism and a 27.9% dropout rate, while Pulaski Early Education Center (PK-K) shows a 33.6% absenteeism rate—double the state average.
The most striking finding is the spending-achievement paradox: The Bayard School spends $22,651 per student—nearly double Odyssey’s $11,529—yet achieves proficiency rates 30-40 points lower. Attendance appears to be the strongest predictor of success, as schools with lower chronic absenteeism consistently outperform regardless of funding. Odyssey’s K-12 continuity and active family choice likely drive its success, while Bayard’s declining trajectory (bottom 3% for three straight years) and Pulaski’s early education attendance struggles highlight where targeted interventions could help. This zip code encapsulates the full spectrum of Delaware’s educational outcomes, from top-tier charter performance to schools facing concentrated poverty and disengagement.
