Original Research by School Decision on Island Park Charter School Inc.
Island Park Charter School Inc. is a single-school charter district in Idaho serving kindergarten through fourth grade. The school sits in the Mack's Inn area of Fremont County, according to publicly reported information from the school's own website. It is a very small operation, with an enrollment small enough that each grade has only a handful of students, and fourth grade in particular has just one or two children. This is a setting where every child is known individually, but the tiny scale also shapes what data is available and what programs a family can expect.
The student body is predominantly white, with a small Hispanic presence and a few students identifying as Asian or two or more races. The school does not report free-or-reduced-price lunch counts, special-education rates, or English-learner figures, so there is no public picture of the economic or special-population makeup. A parent wanting to understand how the school serves children with disabilities or from low-income households would need to ask the school directly.
State assessment results are not available. The school's ISAT proficiency rates in math, English language arts, and science were suppressed across every grade and subject, including grades three through five. With so few students per grade, suppression for privacy reasons is the likely explanation. This is a common pattern in very small schools and does not by itself indicate weak performance. A parent may want to look into this further with the school, asking how student learning is tracked and what internal assessments the school uses to gauge progress.
No graduation rate applies here, because the school does not serve high school grades. No locale brief, housing data, community economic context, or neighbor comparison was available for this district, so there is no public picture of the surrounding housing market or how this school's academic context compares to nearby districts in Fremont County. No civil-rights data, course-access information, staffing figures, attendance data, discipline records, or program offerings were reported either. These gaps leave a thin public record, and a family considering this school would be relying heavily on direct conversation with staff rather than on published metrics.
What the public record does show clearly is a planned expansion. Island Park Charter School is adding seventh grade in the 2026-2027 school year and eighth grade the year after, according to the school's website. This would extend the school from an elementary-only model through middle school, giving families in the area a local public charter option through eighth grade and removing the need to transition children to another school after the early grades. That expansion may change the character of the school over time, adding older students and presumably additional staff and programming.
For a parent weighing this school, the appeal is likely the intimate scale and the continuity that comes with the planned grade expansion. The trade-off is that public accountability data is minimal. State testing is suppressed, demographic and economic details are missing, and no published information about staffing, programs, or discipline is available in the records we reviewed. The school serves only the early elementary band right now, so families looking for a full K-12 pathway would need to plan for the transition years ahead, though the announced expansion narrows that gap. A visit to the campus and a conversation with school leadership would be the most reliable way to fill in what the public data does not.
