Delaware Exceeds National Graduation and Performance Benchmarks

Delaware outperforms the national graduation average of 87.0% with a steady 88.3% success rate. Despite spending just $9,480 per pupil—well below the national $13,000 average—the state maintains a school score of 58.0, surpassing the national median of 50.0.

Consistency Across Delaware's Three Main School Districts

Delaware displays remarkable stability across its three counties, with school scores ranging only from 56.6 to 60.3. While New Castle County maintains the highest performance, the narrow gap between the top and bottom districts suggests equitable standards statewide.
