Summary:
Zip code 49880 is home to a single school, Mid Peninsula School, a K-12 alternative school in Rock, Michigan, serving 220 students within the Mid Peninsula School District.
For parents, this school presents a mixed picture. The most striking strength is science education: 11th graders posted a 53.85% proficiency rate in 2024-2025, nearly 19 points above the state average, and 8th graders also beat the state in science that year. Early elementary math is another bright spot, with 3rd graders hitting 53.85% proficiency versus the state’s 42.7%. However, these wins are offset by serious challenges. Mathematics proficiency falls off sharply by middle school—8th grade PSAT math sits at just 15% compared to the state’s 30.4%—and 8th grade social studies proficiency is a concerning 20% versus the state’s 50.3%. The school also struggles with retention: the graduation rate is only 66.6% against a state average of 84.0%, and the dropout rate of 22.2% is more than triple the state’s 7.1%. With 75.45% of students qualifying for free or reduced lunch, this is a high-poverty school, though it does invest heavily per student at $14,395 with a favorable 13.2:1 student-teacher ratio.
One notable pattern is the “middle school cliff”—students perform well in early grades but lose ground by 6th through 8th grade, only to recover somewhat in high school science and social studies. Year-to-year test scores also swing dramatically due to very small class sizes (likely 15-25 students per grade), so a single student can shift proficiency rates by several points. For families, this means strong science instruction and dedicated early elementary teaching, but parents should be aware of the math gaps and the significant dropout risk. The school’s alternative designation, combined with its role as the only school in the area, suggests it serves a diverse range of student needs, making individual grade-level data less reliable for predicting long-term outcomes.
