Best Public Schools in Zip Code 48173

Zip code 48173, covering Rockwood and Gibraltar, Michigan, is served by five schools within the Gibraltar School District, enrolling roughly 2,900 students across elementary, middle, high, and virtual school levels.

For parents, the standout traditional option is Oscar A Carlson High School, which posts a stellar 96.4% graduation rate and a 0.4% dropout rate—far better than state averages—while also leading the district in 9th grade PSAT reading and 11th grade SAT writing scores. At the elementary level, Chapman Elementary School and Parsons Elementary School both shine in early grades, with 3rd grade reading and math proficiency running 13 to 14 points above state norms; Chapman also excels in social studies and has the district’s lowest chronic absenteeism at 13.4%. The middle years at Shumate Middle School show a dip in M-Step scores, yet 8th graders rebound strongly on PSAT exams, beating state averages by nearly 9 points in reading and 8 points in math. The clear outlier is Lakeshore Virtual School, which struggles with a 51.7% chronic absenteeism rate, a 65.2% graduation rate, and SAT reading proficiency below half the district’s level—though it also serves a higher-poverty population.

Overall, this district offers strong elementary foundations and excellent high school completion, but families should watch the middle school transition, where attendance and engagement drop sharply. Carlson achieves top results with the lowest per-student spending, while Chapman’s higher funding doesn’t consistently translate to better scores year-to-year. For most families, the traditional path through Chapman or Parsons into Shumate and Carlson provides a solid, mid-tier education with notable bright spots in early literacy and high school readiness.
