Summary:
Granger High School is the only high school in the Granger School District, serving grades 9–12 and about 433 students in the Granger, Washington area. The school has a 20.3-to-1 student–teacher ratio and serves a community with substantial economic need, reflected in its 88.68% free or reduced-price lunch participation rate. Because there is only one high school in the district, families cannot compare multiple local high schools and should consider the school’s results alongside district and state measures.
The school’s strongest reported outcome is its 2024–2025 graduation rate of 89.0%, which matched the district rate and exceeded Washington’s 82.6% rate. However, academic proficiency remains a significant concern. In 2025–2026, 30.3% of students were proficient in English Language Arts, 9.38% in math, and 26.92% in science. Math was the clearest weakness: the school trailed the district by 12.43 percentage points and the state by 33.73 points. ELA and science results were slightly better than district results, but all three subjects were well below statewide averages. The school’s reported 11.0% dropout rate for 2023–2024 is also worth monitoring, although it comes from a different year than the state comparison.
Recent trends were mixed. From 2024–2025 to 2025–2026, ELA proficiency fell by 8.0 percentage points and math fell by 6.41 points, while science improved by 3.28 points. Science is a relative local strength, but its performance still trails the state considerably. The school ranked in the 5th statewide percentile in 2025–2026, following results in the 6th and 8th percentiles in the prior two years, indicating persistently low statewide standing despite some numerical rank improvement. Per-student spending was $20,976 in 2023–2024, though spending alone does not explain academic outcomes. Overall, families should weigh the encouraging graduation rate against substantial achievement gaps, especially in math.
