Summary

Mountain Island Charter School is a K-12 public charter school in Mount Holly, NC, serving 1,782 students in the Charlotte area and operating as its own single-school Mountain Island Charter district. About 27.4% of students qualify for free or reduced-price lunch, and chronic absenteeism is 15.4%, down from 17.9% the prior year and well below the 24.2% state average. The 18.7 student-teacher ratio is one of the highest among nearby charter schools, but test results show it has not held students back.

Mountain Island's strongest showing is in elementary and middle school. On 2025-26 EOG exams, average proficiency was roughly 80% in math, 75% in reading, and 81% in science, compared with state averages of 60%, 56%, and 68%. Every grade-level score exceeded the state average, with 5th grade math proficiency reaching 89.4%. Those results place Mountain Island in the same territory as Lincoln Charter School (about 79% math and 76% reading) and ahead of Corvian Community School and Jackson Day School in most subjects. English II end-of-course results are also strong at 79.3% proficiency versus 64.6% statewide. Among nearby schools, only Lake Norman Charter posts higher overall EOG averages.

The clearest area of concern is high school math. Even though 8th grade math proficiency reached 79.4% versus 53.0% statewide, Math I EOC proficiency was just 35.7% in 2025-26 — below the state average of 42.1% and far behind Corvian Community School (83.0%), Lake Norman Charter (76.8%), and Lincoln Charter School (53.1%). Results have also been volatile, ranging from 60.9% in 2023-24 to 28.0% in 2022-23. This disconnect between strong middle school math and weak Algebra I results is worth asking about. For parents weighing their options, Mountain Island looks like a consistently strong choice for elementary and middle grades, with a high school math pathway that deserves a closer look.

Open Quote My daughter goes here and the school administrator focuses only on athletics. They do not have a library for middle or high school students. There is a small selection in the Lower School, but access is restricted to upper school students. They aslo under pay teachers and are not required to have state certified teachers. We are in the process of removimg her from this school. Close Quote
