Summary

Marbrook Elementary School in Wilmington, DE, serves approximately 465 students in Kindergarten through 5th grade as part of the Red Clay Consolidated School District.

Marbrook shows a distinctive pattern: its students perform notably better in upper grades than in lower grades. In 5th grade, math proficiency reached 45.33% and English Language Arts reached 48%, both exceeding district and state averages. The school's 5th-grade Social Studies performance is particularly strong, with 63.51% proficiency, surpassing both district and state levels. However, 3rd-grade ELA proficiency sits at just 26.25% and 4th-grade math at 23.08%, both well below state averages. This "inverted pyramid" pattern suggests the school may have effective intervention programs or particularly strong upper-grade teachers. The school also maintains a favorable 12:1 student-teacher ratio, better than nearby William F. Cooke Junior Elementary (15.7:1) and Brandywine Springs School (15.3:1), potentially allowing for more individualized attention.

Marbrook has historically excelled at serving Hispanic students and those from low socioeconomic backgrounds, ranking in the 79th-86th percentile for these groups in recent years. However, the 2025-2026 school year shows a significant decline across nearly all metrics, with the school's overall ranking dropping from 35th to 64th statewide. Chronic absenteeism at 18.6% exceeds district and state averages, though it remains lower than several nearby schools including Johnson (Joseph E. Junior) Elementary School (25.5%) and Mote (Anna P.) Elementary School. The school's per-student spending of $17,818 is higher than better-performing William F. Cooke Junior Elementary ($13,167) and Brandywine Springs School ($13,934), suggesting that funding alone doesn't determine outcomes. While the current trajectory warrants attention, Marbrook's history of strong upper-grade performance and success with diverse learners suggests it has solid foundations to build upon.
