Marsh Valley High School has seen fluctuating academic performance, with its four-year graduation rate ranging from 78.8% to 82.3% over the past few years, slightly lower than the nearby North Gem High School at 82.3%. The school's test scores are generally below the state averages, with only 19.4% of students proficient or better in ISAT/Math, compared to the state average of 32.3%. However, the school performed better in ISAT/English Language Arts, with 53.7% of students proficient or better, closer to the state average of 60%. Additionally, Marsh Valley High School has faced a concerning trend of high chronic absenteeism rates, ranging from 15.0% to 21.4%, significantly higher than the 15.0% rate reported for the nearby Century High School.

Compared to the nearby North Gem High School, Marsh Valley High School appears to be underperforming in several key areas, such as test scores and chronic absenteeism. The school's relatively low free and reduced lunch rates, ranging from 6.47% to 19.75%, suggest that the school may not be serving a predominantly low-income student population, which could be an important factor to consider when analyzing the school's performance and identifying potential areas for improvement.
