The school shows a standout strength in 4th grade mathematics, where 74.14% of students are proficient—nearly 25 percentage points above the state average of 49.28%. However, performance is uneven: 3rd grade reading proficiency is 46.81%, which falls below the state average of 51.08%, and 5th grade science proficiency is only 38%, though this is above the district (25.63%) and state (29.57%) averages.

Key takeaways for parents include significant year-over-year volatility in test scores, such as 4th grade math jumping from 52.24% to 74.14% proficiency and 5th grade reading dropping from 70% to 53.52% between recent school years. This suggests performance can vary greatly depending on the cohort of students. While the school excels in 4th grade math, it struggles with early literacy in 3rd grade and science in 5th grade, indicating areas where additional support may be needed. Overall, Grulla Elementary is a high-poverty school with strong resources but inconsistent academic results across grades and subjects.
