Academically, Guilford High School substantially outperforms the state across all tested subjects.

The school's graduation rate is also slightly higher than the district rate of 95.7% and significantly higher than the state's 91.2%. However, the most recent year shows a downward trend in all three subjects, with science experiencing the largest decline of 5.6 percentage points, causing the school's ranking to slip from 5 stars and the 91st percentile to 4 stars and the 85th percentile.
One notable area of concern is chronic absenteeism, which sits at 13.2% for Guilford High School—higher than the district average of 8.9% but lower than the state average of 16.4%.

Maintaining engagement and addressing attendance will be important to sustaining its high performance in the future.
