Summary:
The Indian River School District in Delaware is home to three middle schools—Georgetown Middle School, Selbyville Middle School, and Millsboro Middle School—all serving grades 6-8 in a district that ranks in the 71st percentile statewide.
Selbyville Middle School is the clear standout, ranking among Delaware's top middle schools with a 4-star rating and outperforming district and state averages in every subject and grade level. Its 7th-grade ELA proficiency (64.5%) is more than 21 points above the state average, and its 8th-grade science proficiency (29.7%) nearly doubles the district average. Georgetown Middle School sits in a stable middle position with consistent 3-star ratings, showing particular strength in 7th-grade math (43.1% vs. 31.6% statewide) but experiencing a notable drop in 8th-grade scores. Millsboro Middle School is the lowest-performing school, with a 2-star rating and scores below district and state averages across nearly all subjects, including just 11.2% proficiency in 8th-grade science.
The most striking finding is the correlation between chronic absenteeism and performance. Millsboro has the highest absenteeism rate (22.0%) and the lowest test scores, while Georgetown has the lowest absenteeism (14.0%) and performs at or near district averages. Interestingly, Millsboro spends more per student ($14,048) and has a lower student-teacher ratio (13.6:1) than Georgetown, yet produces weaker outcomes—suggesting that instructional quality and school culture matter more than resources alone. The achievement gap between Selbyville and Millsboro is substantial (23.5 points in ELA), indicating the district could benefit from sharing Selbyville's successful practices with its struggling school.
