How Baltimore Polytechnic Institute compares with Maryland and U.S. medians
What stands out at Baltimore Polytechnic Institute
Baltimore Polytechnic Institute is a large high school in Baltimore, Maryland, enrolling 1,632 students.
Class loads run heavy: 21.2:1 is larger than about 98% of Maryland schools and 46% above the 14.5:1 state mean, so each teacher carries more students than is typical.
Its free-meal eligibility rate of 43.2% lands close to the Maryland typical range, neither a high- nor low-need campus by this measure.
By headcount it is one of the larger campuses in Maryland, bigger than 96% of state schools at 1,632 students.
Its Resource Investment Index lands in the lower third of 1,382 scored Maryland schools.
Among 82 similarly sized, similarly resourced-need Maryland schools statewide, it ranks #66, in the lower tier once campus size and economic need are matched.
Its student body is led by African American (59%) and White (21%) (diversity index 59/100).
On the academic-pipeline side it reports 20 Advanced Placement courses.
Counselor availability sits well past the ASCA benchmark, roughly 326 students sharing each counselor, though short of the most stretched campuses.
Chronic absenteeism is elevated: 36.6% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 15.3% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Baltimore's high schools, it stands alongside Dundalk High (2,087 students): Baltimore Polytechnic Institute is smaller than that campus by headcount and runs heavier classes (21.2:1 vs 15.5:1).
Baltimore City Public Schools also operates Mergenthaler Vocational-Technical High (1,714 students) and Baltimore City College (1,470 students) alongside Baltimore Polytechnic Institute.
