Summary:

Zip code 21639 is home to a single school, Greensboro Elementary School, a Pre-K through 5th grade institution within the Caroline County Public Schools district that serves 840 students in a community where over three-quarters of students are economically disadvantaged.

Greensboro Elementary School presents a mixed academic profile with a notable strength in mathematics. For the 2025-2026 school year, the school achieved a 33.7% math proficiency rate, significantly outperforming both the district average of 23.7% and the state average of 27.1%. This strength is particularly impressive given that 76.67% of students qualify for free or reduced lunch. However, the school struggles in English Language Arts, where its 45.6% proficiency rate falls below the district's 50.8% and the state's 51.7%. Science scores for 5th graders also lag behind, with only 23.5% proficient compared to the state's 32.4%. The school's chronic absenteeism rate of 20.8% is notably better than the district's 28.0%, suggesting stronger student engagement. With a student-teacher ratio of 12.9:1 and per-student spending of $18,965, the school invests heavily in its students, though results vary by subject.

A deeper look at math performance reveals a concerning grade-level trend. While 3rd graders slightly exceed the state average in math (43.4% vs. 42.6%) and 4th graders perform on par (36% vs. 34.8%), 5th-grade math proficiency drops sharply to 21.9%, well below the state average of 30.2%. This decline suggests a potential challenge with upper-grade math concepts that may require targeted intervention. Overall, Greensboro Elementary School demonstrates that it can achieve strong results in mathematics despite high economic need, but faces clear opportunities for improvement in literacy and upper-grade math instruction.
