Summary:

Zip code 21029 in Clarksville, Maryland, is home to a single high school, River Hill High, which serves grades 9 through 12 and is part of the highly-rated Howard County Public Schools district.

River Hill High is an elite academic performer, consistently ranking in the top 5-6% of all high schools in Maryland. Its English Language Arts (ELA) proficiency is exceptional, with 93.3% of students scoring proficient, far exceeding the district average of 65.9% and the state average of 51.7%. The school also shows strong overall math proficiency at 49.4%, well above the state average of 27.1%, and has demonstrated impressive year-over-year growth in this subject. The graduation rate is a solid 94.8%, and chronic absenteeism is low at 13.6%. The school serves a very affluent population, with only 7.66% of students receiving free or reduced lunch.

An interesting finding is the "Algebra I Paradox": while the school excels in most subjects, its Algebra I proficiency (17.8%) is below the district average (41.2%). This likely indicates that many students take Algebra I in middle school, meaning the high school cohort taking the exam is smaller and less advanced. This is supported by the school's high Algebra II proficiency (58.4%), which is more than double the state average. Overall, River Hill High is a standout school of excellence within an already strong district, offering a top-tier education with a particular strength in ELA and advanced mathematics.
