Timberlake stands out for its strong academic performance and excellent attendance. In science, 64% of students are proficient, far exceeding the state average of 42.6%, while English Language Arts proficiency reaches 74.6% versus 53.9% statewide. These are substantial advantages of roughly 20 percentage points. Math proficiency is above the state average (46.5% vs. 43.1%) but trails the district average of 51.8%, indicating a relative weakness in that subject. The school also excels in attendance, with a chronic absenteeism rate of just 6.1%—less than half the state's 13.8%. However, the graduation rate of 82.5% matches the state average exactly, meaning it is not yet a distinguishing strength.
Despite strong test scores, the school's state percentile ranking has declined notably, from 83rd in 2021–2022 to 54th in 2023–2024, though it still earns a 3-star rating. About 24.66% of students receive free or reduced lunch, indicating a relatively moderate level of economic disadvantage. The student–teacher ratio is 16.7, and per-student spending was $9,680 in 2018–2019. Overall, Timberlake Senior High School is a strong, above-average school with genuine strengths in science, ELA, and attendance, while math and graduation rates offer areas for continued improvement.
