High Schools in Grand Blanc Community Schools

Grand Blanc Community Schools is served by a single, large public high school, Grand Blanc Community High School, which enrolls 2,377 students across grades 7 through 12 in a suburban Michigan setting.

For parents, the most important takeaway is that Grand Blanc Community High School is a strong performer in graduation and literacy, but shows clear weaknesses in math and attendance. The school’s graduation rate is excellent at 94.4%, far above the state average of 84.0%, and its dropout rate of 3.1% is less than half the state’s 7.1%. In English Language Arts, students consistently beat state averages—67% of 9th graders are proficient on the PSAT, and 56.9% of 11th graders meet the SAT reading benchmark. However, math proficiency lags: only 24.2% of 11th graders meet the SAT math benchmark, and 9th and 10th grade PSAT math scores (32.3% and 28.8%) also fall below state averages. Science proficiency is similarly modest at 39.1%.

One notable concern is chronic absenteeism, which sits at 27.1%—higher than the district’s own average of 24.1%, suggesting this is a school-specific issue. The school also has a relatively high student-teacher ratio of 21.1, which may limit individualized attention, especially given that 44% of students are economically disadvantaged. Interestingly, the school’s state ranking improved dramatically from the 53rd to the 67th percentile in one year, yet this jump appears driven more by graduation rates and ELA scores than by math or science. Parents should also note a clear drop-off in performance between 9th and 10th grade in both subjects, indicating the transition to upper-level coursework is challenging. Despite these academic struggles in math, the school’s high graduation rate suggests effective credit recovery or alternative pathways may be helping students finish, even if state test scores don’t fully reflect mastery.
