Frequently asked questions
What is the best elementary school in Delaware?
Shortlidge (Evan G.) Academy in Wilmington ranks first among elementary schools in Delaware with a Success Index (US) of 92.3 out of 100 (Enrollment: 340).
How are elementary schools in Delaware ranked?
Each school's Success Index (US) combines 4 factors: math proficiency (30%), reading proficiency (30%), community advantage (fewer free/reduced-price lunch) (25%), students per teacher (15%). Each factor is a percentile against schools of the same type across United States. Schools with fewer than 60 students are excluded from rankings.
Are these 2025 rankings official?
No. They are computed by Success Tutoring from official American data (Urban Institute Education Data Portal (NCES CCD, EDFacts); NCES Common Core of Data). States set their own assessments and proficiency cut scores, so proficiency rates are most comparable within a state. Use the state rankings for like-for-like comparisons.
