Summary
Appoquinimink High School in Middletown, DE, is a large public high school serving 1,357 students in grades 9-12, and it stands out as one of the top-performing schools in the state, ranking 7th out of 41 high schools for the 2025-2026 school year.
For parents, the most reassuring news is that Appoquinimink delivers strong academic results across the board. The graduation rate is a standout at 94.6%, well above the state average of 88.9%, and the dropout rate is just 2.0%—half the state average. On the SAT, 55.22% of 11th graders were proficient in English Language Arts and 26.57% in Math, both significantly higher than state averages (44.02% and 18.16%, respectively). The math proficiency rate is particularly impressive, nearly 50% higher than the state average and the highest among the three high schools in the Appoquinimink School District. The school also excels in early high school science, with 52.81% of 9th graders proficient, a full 15 points above the state average. When compared to nearby schools, the difference is stark—Glasgow High School has a 0-star rating and an ELA proficiency rate of just 18.97%, while Newark High School graduates only 71.3% of its students. Appoquinimink is clearly a regional academic leader.
However, there are two important caveats. First, chronic absenteeism is a significant concern—24.0% of students were chronically absent in 2024-2025, far higher than the district (14.0%) and state (17.1%) averages, though this rate has been improving from 31.8% two years ago. Interestingly, this issue is shared by its in-district peers, Odessa High School (23.9%) and Middletown High School (22.5%), suggesting a community-wide factor. Second, while the school performs exceptionally well for Hispanic students (ranked 4th statewide), recent data shows a sharp decline in performance for African American students, dropping from 5th to 22nd place in a single year—a trend worth monitoring. On a positive note, the school is efficient with resources, spending $12,932 per student, far less than schools with worse outcomes like Newark High ($20,046) and Glasgow High ($20,800).
