Summary
Middletown High School is a large public high school in Middletown, DE, serving 1,231 students in grades 9-12 as part of the highly-rated Appoquinimink School District. This school stands out for its exceptional graduation rate of 96.6%—nearly 8 points above the state average—and its consistently strong performance in English Language Arts, where 60.92% of 11th graders scored proficient on the SAT, far outpacing the state average of 44.02%. The school has maintained a top-10 state ranking for most of the past decade, earning 4-star ratings in 8 of the last 10 years, and it is particularly effective at supporting its African American and Hispanic students, who rank in the 69th and 70th percentiles statewide respectively.
While Middletown excels in literacy, math proficiency is a notable weakness, with only 28.17% of students proficient on the SAT—still above the state average of 18.16%, but a significant drop from its ELA scores. Chronic absenteeism is also a concern, with a rate of 22.5% in 2024-2025, well above both the district (14.0%) and state (17.1%) averages. Interestingly, despite this attendance challenge, the school still manages to achieve high academic outcomes and graduation rates, suggesting that students who attend regularly are well-supported. Compared to its district peers, Odessa High School and Appoquinimink High School rank slightly higher overall, but Middletown outperforms both in SAT ELA proficiency, while lagging in 9th-grade science.
When compared to nearby schools in other districts, the difference is striking. Newark High School, Penn (William) High School, and Glasgow High School all rank significantly lower and have much lower test scores—Middletown's ELA proficiency is nearly double Newark's. Notably, Middletown achieves these results with lower per-student spending ($12,738) than many nearby schools, indicating highly efficient use of resources. For parents, this school offers a strong, stable learning environment with a proven track record of graduating students and preparing them for success in reading and writing, though math support and attendance are areas worth monitoring.
