Original Research by School Decision on River Valley Junior- Senior High School
River Valley Junior-Senior High School is a regular public school serving sixth through twelfth grade in the small rural town of Correctionville, Iowa. The town sits along the Little Sioux River and is part of the Sioux City metropolitan area, with US Route 20 and Iowa Highway 31 passing through it. The community shows buildings dating to the late 1800s. There is a city swimming pool, a public library, and a historical museum within the town’s compact footprint. The school uses the Wolverine mascot and belongs to the River Valley Community School District, which also chooses names for the junior-senior high.
The overall student body is small in size, reflecting the surrounding rural population. Enrollment is spread fairly evenly across the grades served, each with a modest number of students. A substantial share of students qualify for free or reduced-price lunch. The school's racial and ethnic composition is predominantly white, with a much smaller share of Hispanic students and a very small number of students identifying as Black or two or more races. No data was available on the share of students with an Individualized Education Program or English learner status.
State assessment results from the Iowa Statewide Assessment of Student Progress provide a picture of academic performance. In math and English language arts, the proficiency rate places the school in the bottom quartile relative to other districts in Woodbury County. Science proficiency was higher. Only a single year of assessment data was available, so no trend can be established. This is a school where a parent may want to discuss the school’s approach to raising proficiency with the administration, particularly in math and reading, as the numbers are below the midpoint for the county.
The district has adopted a four-day school week beginning with the 2026–27 academic year, citing declining enrollment. This is a structural change that directly reshapes family schedules, child care arrangements, and daily routines for any parent with a child in the district. If you are considering this school, the four-day calendar is a central factor for planning.
No course access data was available, so the breadth of AP, dual-credit, or career and technical education offerings could not be confirmed from the provided information. Similarly, there were no data on chronic absenteeism, discipline, staffing, or the graduation rate. A parent looking for that information would want to contact the school directly.
Because the school serves grades six through twelve, families with younger children would need to look at the district’s elementary provision.
The housing market in Correctionville is modestly valued compared to the state and national benchmarks. Home values are well below the state median and even further behind the national figure. The town’s population is very small, with a modest number of housing units and no major new developments identified in publicly reported sources.
Overall, this is a small, rural school operating in a district that has recently changed its calendar structure. Academic proficiency on state tests is below the midpoint for the county, and the school serves a community where most students are white and a significant share comes from low-income households. The school offers a combined junior-senior high model, so students remain in the same building from middle school through graduation. It is a setting where the peer group is stable and class sizes are small by nature. A family considering this school would want to understand how the four-day schedule fits their work life, assess the academic support available in the core subjects, and inquire about the specific programs and pathways offered to high school students, as that information was not in the data provided.
