Cabin Branch Elementary is a standout school that delivers exceptional academic results.

The school is also on a strong upward trajectory, with year-over-year gains of nearly 7 percentage points in both Math and ELA, and an impressive 11.3 percentage point jump in 5th-grade Science. This rapid improvement, combined with a low chronic absenteeism rate of 14.7% (compared to the district's 22.6%), suggests a highly effective and supportive learning environment.
While overall performance is excellent, a notable trend emerges in math scores by grade level. Proficiency drops from 78.8% in 3rd grade to 56.6% in 5th grade, a decline of over 22 percentage points. Although the 5th-grade score still far exceeds district and state averages, this pattern is worth investigating.

With a moderate free/reduced lunch population of 28%, Cabin Branch Elementary proves to be a high-performing school that is rapidly improving and well-equipped to support its students.
