Summary:
Zip code 19966 in Millsboro, Delaware, is served by two elementary schools—East Millsboro Elementary School and Long Neck Elementary School—both part of the highly-rated Indian River School District, which holds a 4-star rating and ranks in the 71st percentile statewide.
These two schools offer complementary academic strengths, making the choice largely dependent on your child's needs. East Millsboro Elementary School (820 students) shines in 5th Grade Social Studies, where 64.23% of students are proficient—outperforming both the district (59.08%) and state (61.85%) averages. It also has a slight edge in 5th Grade ELA (39.52% vs. 33.05%). Meanwhile, Long Neck Elementary School (712 students) is the stronger choice for mathematics, particularly in 4th Grade (46.15% proficiency, nearly 6 points above the state average) and 3rd Grade (41.59%). Long Neck also holds the better current ranking (69th vs. 73rd), has lower chronic absenteeism (15.2% vs. 17.6%), and a slightly better student-teacher ratio (15.4:1 vs. 16:1). Notably, East Millsboro spends $837 more per student yet achieves lower overall rankings, raising questions about resource efficiency.
Both schools face significant challenges, particularly in English Language Arts, where proficiency rates run 10-14 points below state averages across all grade levels. Ranking trends are also concerning—East Millsboro has fallen 21 positions over three years (from 52nd to 73rd), while Long Neck dropped from 60th to 69th. There is also notable year-to-year volatility, such as East Millsboro's 15.85-point drop in 4th Grade Math. Interestingly, both schools have lower chronic absenteeism than the district average (20.2%), yet still lag state benchmarks, suggesting other factors like curriculum or socioeconomic conditions are at play. The dramatic 44-point gap between East Millsboro's 5th Grade Social Studies (64.23%) and its 4th Grade score (20.37%) hints at a possible exceptional teacher or specialized program worth investigating.
