Xavier Charter School, Twin Falls ID

Original Research by School Decision on Xavier Charter School

Xavier Charter School sits on the western edge of Twin Falls, serving students from kindergarten through twelfth grade under a single roof. As a public charter school, it operates with its own governance structure rather than as part of the Twin Falls School District, and families choose to enroll here rather than being assigned by attendance boundaries. The school was publicly reported as renewed for a six-year operating contract in 2024, with the term running through June 2030, which gives families a measure of operational continuity.

The enrollment is modest for a K-through-12 school, with each grade cohort in the mid-fifties to low-sixties range in the elementary and middle grades, tapering to smaller classes in the high school years. The student body is predominantly white, with a Hispanic enrollment of about one in five students and small representation from other racial and ethnic groups. Just under a third of students qualify for free or reduced-price lunch, which is below what many public schools in the region serve. Data on students with individualized education programs and English learners was not available, so those population sizes are not described here.

Twin Falls itself is the regional commercial hub for south-central Idaho and northeastern Nevada, a planned community founded on a broad plain at the south rim of the Snake River Canyon. The city has grown steadily and serves as the county seat and principal city of a metropolitan statistical area spanning Twin Falls and Jerome Counties. A distinct downtown core with a traditional street grid anchors civic life, but the city is largely auto-oriented, spread across roughly twenty square miles. The Snake River Canyon forms the northern boundary, and landmarks like Shoshone Falls and the Perrine Bridge define the area's character. The College of Southern Idaho, a large community college, sits in the northwestern part of the city, with three state universities offering classes on that campus. The city launched a microtransit system in 2023 that quickly exceeded ridership projections.

On state assessments, Xavier's results vary across grades and subjects. In English language arts, proficiency rates across the tested elementary and middle grades land in a band running from the low forties to the low sixties, with the higher results in fourth and eighth grades. Mathematics follows a similar pattern of mixed outcomes, with third grade and eighth grade showing the strongest proficiency among the grades with reported results, while sixth grade sits lower. Several grade-level results in math and science were suppressed or reported only as ranges, which limits the ability to characterize those grades precisely. No high school assessment data appears in the available results, and no graduation rate was reported in the data provided. A parent considering the high school grades may want to ask the school directly about graduation outcomes, college placement, and any dual-credit or advanced course offerings, since none of that information was available in the data reviewed here.

The housing market in the school's zip code sits below the Idaho state benchmark for typical home values, with rents that are modest relative to many metropolitan areas. Mortgage rates have been hovering in the mid-six percent range. This is a community where housing costs remain more accessible than in much of the state, though prices have been rising at a modest year-over-year clip.

What the data shows is a charter school of moderate size in a growing regional center, with academic results that fluctuate across grades and subjects rather than painting a uniformly strong or uniformly weak picture. The charter renewal through 2030 provides some assurance of continuity. What is missing is substantial: no graduation rate, no high school testing results, no staffing ratios, no course access information, no discipline or attendance data, and no program descriptions. Families evaluating Xavier for the upper grades especially would benefit from asking the school directly about what it offers and how its graduates fare.

The federal source publishes a banded range instead of an exact rate when the graduating cohort is small enough that an exact number could risk identifying individual students.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
