Calvert County Public Schools

The Calvert County Public Schools district in Maryland serves 24 schools, including 12 elementary, 6 middle, 5 high schools, and 1 alternative school, and is ranked 3rd out of 25 districts in the state, earning a 5-star rating. The district excels overall, with an average English Language Arts proficiency of 66.6% and Math proficiency of 37.9%, both well above state averages, but performance varies significantly across schools, often linked to socioeconomic factors like free/reduced lunch rates and chronic absenteeism.

Standout schools include Northern Middle, the district's top middle school ranking in the 92nd percentile, with exceptional advanced coursework results like 91.3% proficiency in Geometry and low chronic absenteeism at 10.8%. Sunderland Elementary leads elementary schools with a 95th percentile ranking and 79.1% ELA proficiency, while Mount Harmony Elementary also shines with 68% Math proficiency. In contrast, Southern Middle struggles with only 16.1% Math proficiency and a 26.9% chronic absenteeism rate, and Calvert High faces challenges with a 10.6% dropout rate and 14.3% Math proficiency. High schools like Northern High and Huntingtown High School excel in ELA, with rates above 82%, but Math remains a district-wide weakness at the high school level.

A key finding is the "two districts" phenomenon, where northern schools like Northern Middle and Sunderland Elementary consistently outperform southern schools like Patuxent High and Patuxent Appeal Elementary Campus, which have higher poverty and absenteeism rates. Chronic absenteeism is a critical warning sign, with schools above 20% absenteeism—such as Calvert High and Southern Middle—showing the lowest test scores. Interestingly, spending per student does not directly correlate with performance; high-spending schools like St Leonard Elementary ($21,782) underperform, while low-spending schools like Mount Harmony Elementary ($15,570) excel, suggesting resource allocation matters more than total spending.
