Summary:
The Gibraltar School District is served by a single high school, Oscar A Carlson High School, located in Rockwood, MI, which enrolls 1,104 students across grades 9 through 12.
Oscar A Carlson High School stands out for its exceptional graduation rate of 96.4%, far surpassing the state average of 84.0%, alongside a remarkably low dropout rate of just 0.4%. The school has also shown significant improvement, jumping from the 40th to the 60th percentile in state rankings between the 2024-2025 and 2025-2026 school years. In terms of academics, the school excels in English Language Arts, with 56.2% of 11th graders proficient in SAT Evidence-Based Reading and Writing (compared to 52.1% statewide) and 66.4% of 9th graders proficient in PSAT ELA (versus 60.2% statewide). However, there is a stark contrast in STEM subjects: SAT Math proficiency sits exactly at the state average (26.5%), while M-Step Science proficiency (28.8%) and Social Studies (34.4%) both lag behind state averages of 35.2% and 43.2%, respectively.
For parents, the key takeaway is that Oscar A Carlson High School is highly effective at ensuring students graduate, but academic proficiency is uneven. The school’s strong ELA results and improving state ranking suggest positive momentum, yet the below-average science scores and average math performance indicate areas where students may need extra support. Chronic absenteeism affects 24.3% of students—better than the state’s 27.9% but still notable given the high graduation rate. With a student-teacher ratio of 22.9 and per-student spending of $13,911, families should consider whether the school’s resources align with their child’s needs, particularly in math and science, while recognizing the school’s clear strengths in literacy and student retention.
