The top reported proficiency rate is 80% in English language arts. The lowest is 53% in Science.
Original Research by School Decision on St. Croix Preparatory Academy
St. Croix Preparatory Academy is a single charter school district in Washington County, Minnesota, serving kindergarten through twelfth grade as one K-12 program across three school buildings: a lower school, a middle school, and an upper school. It is a charter school, meaning it is publicly funded but operates independently of the local school district structure, and families must choose to enroll here rather than being assigned by residence.
Academically, this is a high-performing school. On the Minnesota Comprehensive Assessments, proficiency rates in math and English language arts were consistently well above average across every tested grade level, with many grades posting proficiency rates that placed the school in the top quartile of all Washington County districts. The school’s overall proficiency index, a combined measure across subjects and grades, was the strongest in the county among the eleven districts compared. This is a school where, on state tests, the large majority of students meet or exceed standards. Science results were more mixed. In fifth grade, about half of students scored proficient, and in eighth grade the figure was slightly higher. The science assessments underwent a name change and cut-score change recently, which makes direct comparison to prior years unreliable, but the fifth-grade number in particular is a softer spot where a parent may want to ask the school how science instruction looks across elementary grades.
The graduation rate field was not available in the data provided. For a high school that serves twelfth grade, this is a meaningful gap, and a family considering the upper school would want to confirm the school’s graduation rate directly.
Student composition at St. Croix Prep is predominantly white, with a notable Asian student population and smaller shares of Black, Hispanic, and multiracial students. The district did not report the share of students who qualify for free or reduced-price meals, nor did it report counts for students with disabilities or English learners. Those are gaps that make it harder to assess the full range of student supports and the school’s socioeconomic diversity. A parent for whom these factors matter should ask the school directly.
On discipline and school environment, the available data shows a low chronic absenteeism rate, the lowest in the county among the districts compared. This suggests strong daily attendance patterns and a student body that shows up consistently. Per-pupil current spending falls in the middle range among Washington County districts but in the lower half of that middle range, meaning the school operates on a leaner budget than many of its neighbors. For a charter school, that is not unusual, but it is a point of interest if program depth or class size is a priority.
The district brief notes that no specific recent changes affecting parents were found through a search of publicly reported information. The school appears stable in its operations and offerings without major recent disruptions.
This is a school that delivers strong academic results on state tests, particularly in math and reading, and has high daily attendance. It operates as a charter with a college-preparatory name and structure, and its student body is homogeneous in the proportion of white students relative to the county. The convenience of being a single K-12 charter means one campus identity and a consistent academic culture from kindergarten through high school, but it also means no neighborhood boundaries or busing guarantees. For families seeking a school where state test scores are well above the local norm and where attendance patterns are strong, this fits. For those wanting data on economic diversity, special education services, or English language support, the missing information is a limitation worth asking about.
