Funding and Resources
Public school districts in South Dakota spend approximately $11,000 per student per year on average (state-level estimate; district-level figures vary), below the national average (U.S. average: $13,700/year).

District Scale and Program Breadth
Armour School District 21-1 is a small, community-focused district with 3 schools serving students from K–12. The district enrolls approximately 219 students in total. Small districts often benefit from tighter community cohesion, more personalized teacher-student relationships, and stronger parental involvement.

Understanding the 3/10 Rating
SchoolDistrictFinder rates Armour School District 21-1 5 out of 10 — average among South Dakota public school districts. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection (2021–22 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score.

Average-rated districts provide foundational public education, and many families find they deliver solid day-to-day learning — particularly when parents stay engaged.

Average districts often have individual schools that significantly outperform the district mean.
